III. Safety suggestions for programming

1) Setting a coordinate system

Incorrect coordinate system may cause the machine not to work as expected even if the program is correct, which may injure the operator, and damage the machine as well as its tool and workpiece.

2） Rapid traverse (positioning)

When G00 rapid traverse performs the positioning (nonlinear motion to position between its starting point and end point), make sure that the path for the tool is safe before programming. The positioning is to perform the rapid traverse, and when the tool and the workpiece are interfered, the tool, the machine and the workpiece may be damaged, and even the operator injured.

Contents

3） Applicability of user manual

The manual introduces in detail all functions of the system, including optional functions and max. controllable ranges, which are subject to change with the machine. Therefore, some functions discribled in this manual will not work out for other specified manchines.If there is any doubt, please read the instruction for the machine.

4） Functions of CNC system and machine

CNC machines depend on CNC systems, but also power voltage cabinets, servo systems, CNC and the operator panels. It is hard to explain all the integrated functions, programming and operation. Do not use integrated instructions not included in the manual until they have been tested successfully.

IV. Notes and Safety Suggestions for Operating Machine

1) Before parts processing Test the machine without workpiece or tools. Make sure that the machine runs well before it starts to work.

2) Before operating the machine Check the input data of the system carefully before operating the machine. Incorrect input data may cause the machine to work improperly, and damage the workpiece and the tool, as well as injure the operator.

3) Adaptations between appointed federate and machine operations Make sure that the input feedrate of the system is suitable for the expected operation. Feedrate has a maximum for each machine, and the amount of the feed rate is subject to change with operation. Choose the maximum according to the instructions of the machine. Improper feedrate leads the machine to work wrongly, and damage the workpiece and the tool, as well as injure the operator.

4) Compensation function When offset is needed, check the direction and the amount of the compensation. Improper compensation causes the machine to work wrongly, and damage the workpiece and the tool, as well as injure the operator.

5) Manual operation

If the machine is to run in JOG working mode, check the current position of the tool and the workpiece, and correctly specify the moving axis, moving direction and the feedrate. MPG (Hand wheel) control with great override, such as 100%, rotate MPG (used to call electric hand wheel), then the tools and workbench will move fast, which may lead the stop of the MPG. However, the tools and workbench will not stop immediately. The high override of MPG movement may damage the machine and its tool, even injure the operator.

6) MPG returns to the reference point

If the tool is return to the reference point, make sure that the machine has been equipped with the device to detect the reference point; otherwise, the tool cannot reach the reference

Operation Chapter One Overview

OPERATION

Chapter 1 Overview

GSK96 is a newly-developed multi-function position control system with the precision control function of μm level for Z/X/Y axis. The single-axis, double-axis or three-axis control can be set by parameters. This system can realize motion functions such as positioning and feeding, two-axis linkage, taping and threading, rotation indexing and servo spindle control, and has plenty of input/output signal control functions, which can realize complicated control of multi-signal detection and output.

GSK96 control system is applicable to the control like indexing drilling, grinding, taping and feeding, cutting and welding rather than the control of the turning machine.

This product is easy to operate and has a visible lattice true color LCD interface with resolution of 800X480. It is characterized by its powerful functions, stable performance, full-screen program editing, Chinese operation interface, outstanding safety, machining precision and machining efficiency as well as the high cost performance. In addition, it employs the international standard CNC language ISO code to write programs.

Technical Specifications:

This chapter introduces operations and notes of the system. Please read carefully before operation.

4.1 System ON/OFF, Initial State, Modal, and Safe Protection

4.1.1 Power on

There is no power switch on the operation panel of the system. The operator installs it according to the different machine to avoid bad effects to CNC system owing to the impaction of power supply. Check before the system is turned on:

1) Ensure the machine state is normal;

2) Ensure the voltage meets the requirements;

3) Ensure the wiring is correct and firm.

The system is turned on as follows:

1) The master power switch of machine is turned on. Switch on the power switch of the CNC system, and the system displays as Fig. 4-1. Press any keys, and the system enters into EDIT working mode.

Fig. 4-1 System initialization display window

2) The system orderly completes the following work after power-on:

 The system controls the program loading.  The system automatically checks itself and executes the initialization.  The system loads and checks parameters.  I/O interface initialization.  The system loads and checks the operator programs.

【Note】

1) Must not press any keys on the system panel when the system is turned on. Press

RESET key when the system enters the press key test window at the moment.

【Note】

1) The system should be checked itself and initialized when it is turned on at first (it is

completed by the machine manufacturer, and the operator cannot execute the operation, otherwise, the parameter set by the machine manufacture will lose).

2) Operations related to turn off the machine power supply are referred to the operator manual machine manufacturer.

4.1.3 System, program initial and modal

4.1.3.1 the initial state and modal of the system The initial mode of the system is defined to be a special initial state of all functions set by itself when

the system is turned on; all auxiliary functions do not execute the actual output. The modal of the system is defined to be their kept states after the system executes all functions. Initial mode and modal of the system:

4.1.3.2 Initial mode and modal of program The initial mode is the automatic initialization setting state before the system executes the machining

program; i.e. the initial default state of the default programming word and speed word.

Program initialization state of the system: G command：G00, G97, G98; Cutting speed：30mm/min; Miscellaneous function: current state; System coordinates: current coordinates are those of the last automatic executing

program or manual operation G modal is always valid till it is changed by other modal commands in the same group after the word is set. After the modal meaning is set, the G command may not be input again when the

Page 28

GSK96 Multi-function Position Control System User Manual

same function is used in the later block. There are three groups of G command with modal characteristics, and there is only one command in the modal state:

Group 1：G00, G01; (initial mode：G00 ) ; Group 2：G96, G97; (initial mode：G97 ) ; Group 3：G98, G99; (initial mode：G98 F30 ) ;

The command without modal characteristics has effect in the block and must be defined to use every time.

【Note】 In AUTO working mode, the system automatically recovers to the program initial mode when it executes the first command of workpiece program or executes the first block command after M20, or selects the middle block as the first command.

4.1.4 Safe protection

The CNC system sets a perfect protection measure to prevent the operator from danger and the machine from being damaged.

4.1.4.1 Hardware limit protection The system can check the travel limit switch installed on the machined. When the machine slide

moves to press the travel limit switch, the system stops feeding instead of closing other miscellaneous functions, and the program stops running and the system displays the hardware limit alarm information of corresponding axis. After the travel limit switch alarms, the system can select JOG working mode, the key for axis movement which is reversed to the limited direction is pressed, i.e. the system exits the travel limit and the travel limit switch alarm automatically disappears on the screen.

【Explanation】

1） X, Y, Z positive limit check shares one pin LT+, and their negative limit check shares one pin

LT-; when the positive limit alarms, all axes cannot move positively but move negatively; and vice versa.

2） When the travel limit switch runs across the limit block, the limit signal appears; the valid

length of limit block signal is more than 30mm or more to avoid rush out the valid area of the signal.

3） When the parameter is set to ―limit emergency stop‖ mode (bit parameter P402_d7=1), and

the system runs across the limit block, there may be great deviation between the coordinates

displayed by the system and the actual position. Adjust the machine coordinates. 【Relative parameters】 Bit parameters: P402_d7, P404_d6, P404_d1.

Bit parameter P402_d7 sets the hardware limit alarm mode; Bit parameter P402_d6 sets whether the hardware limit alarm checks;

Page 29

Operation Chapter Four System Operation

Bit parameter P402_d1 sets the hardware limit alarm level of each axis; When P404_d1=1 is high level alarm, the positive limit switch +X, +Y, +Z of each axis are normally closed contact, are connected to X/Z/Y positive limit input interface +LT (they are open and the system alarms) in serial; the negative limit switch -X, -Y, -Z of each axis are normally closed contact, are connected to X/Z/Y negative limit input interface -LT (it is off and the system alarms) in serial; it is suggested that the operator should select in prior the hardware limit to the normally closed contact of each axis as follows:

When P404_d1=0 is low level alarm, the positive limit switch +X, +Y, +Z of each axis are normally open contact, are connected to X/Z/Y positive limit input interface LT+ (they are closed and the system alarms) in serial; the negative limit switch -X, -Y, -Z of each axis are normally open contact, are connected to X/Z/Y negative limit input interface LT- (it is off and the system alarms) in serial; the connection is as follows:

4.1.4.2 Software limit safe protection

1） Mechanical software limit safe protection

The mechanical software limit safe protection is to limit machine coordinate motion range to avoid slide to exceed the motion range. The mechanical software limit alarms when the machine position (machine coordinates) exceeds the range. Releasing overtravel alarm methods: reversely movement in JOG working mode (negatively moves for positive overtravel; positively moves for negative overtravel).

2） Tool nose software limit safe protection

The tool nose software limit safe protection is to limit tool nose coordinate motion range to avoid the tool nose to exceed the motion range. The tool nose software limit alarms when the machine position (tool nose coordinates) exceeds the range. Releasing overtravel alarm methods: reversely movement in JOG working mode (negatively moves for positive overtravel; positively moves for negative overtravel).

【Explanation】

1) The coordinate axis decelerates to stop when the coordinates exceed the software limit range during the motion.

【Relative parameters】

Page 30

GSK96 Multi-function Position Control System User Manual

P009, P010: max. travel of Z positive, negative tool nose software limit; P011, P012: max. travel of X positive, negative tool nose software limit; P013, P014: max. travel of Y positive, negative too nose software limit; P015, P016: max. travel of Z positive, negative mechanical software limit; P017, P018: max. travel of X positive, negative mechanical software limit; P009, P010: max. travel of Y positive, negative mechanical software limit; Bit parameter P404_d4, P404_d3 separately sets whether the mechanical, tool nose software limit alarm are valid.

4.1.4.3 Emergency stop alarm (emergently stopping the system) When there is the external emergency stop input terminal ESP in the system input interface, the

operator should connect the emergency stop button Normally closed contact on the machine panel with the emergency stop input terminal. Press Emergency stop button and the system enters the emergency stop state. The system stops all feed and sets the output of all the switch value control such as the spindle and the cooling to be invalid, disaplying ―Emergency Stop Alarm‖.

After the emergency stop condition is released, the operator should rotate the emergency stop

button clockwise based on the up arrow, the button automatically releases to cancel the emergency stop signal.

When the system is in the emergency stop alarm state and the external emergency stop signal is

cancelled, you can press the ―RESET‖ key to return the previous working mode.

When the system is in the emergency stop state, if the external emergency stop signal is not

cancelled, it is forbidden to operate the system in Manual, Auto and Diagnosis operations; but the user can press RESET key to remove the alarm window, and switch the control to Edit, Parameter or Tool Offset operation mode.

If the emergency signal is not cancelled in Edit, Parameter or Tool Compensation operation,

press RESET key to remove the alarm window, then it is available to operate system.

There is the Emergency stop in the movement, there may be great deviation between the

coordinates displayed the system and the actual position, and the operator must correct the machine coordinates.

When emergency button is pressed, there are a series of procedures to be handled:

1） During emergency stop, the system stops all feed, and terminates program execution; the

spindle stops rotating; cooling and lubricating function is turned OFF.

2） During emergency stop, the system automatically sets the internal stored chuck and tailstock

states to M11 and M79. After the emergency is released, when the foot switch of chuck or tailstock is pressed for the first time, the states become M10, M78.

3） During emergency stop, if such commands as tool exchanging, tailstock, chuck, gear

changing is being executed, the execution should be stopped immediately (cancel the tool post CCW/CW signal; tailstock signal and chuck signal are depends on parameter setting); at this time, the system assumes that the tool post, chuck, tailstock and gear are not in the

Page 31

Operation Chapter Four System Operation

proper position, and red indicator is flickering; only when the emergency stop alarm is released, and above execution is repeated or after system power-on, can the system resume the normal state.

4） During emergency stop, if the output signal of MDLY interface remains the same, interface

control signals other than MDLY, spindle , cooling, lubricating are set by parameters. If P403_d3 is 0, then, only output signals for spindle, cooling and lubricating are turned off; if P403_d3 is 1, all interface control signals including chuck and tailstock signals are turned off.

5） After the emergency stop alarm is cleared, in AUTO mode, the system will exit from dry run

state if it was; in MANUAL mode, the system will turn from rapid traverse state to feed state; if the set F value is not changed, the spindle analog voltage output remains the same; except for that, other functions of the system are in initial state.

6） After the emergency stop alarm is released, time counting of the low-pressure detection

function and auto-lubricating control function are restarted.

【Special Attention】

1）The standard emergency stop function is actually to set the output signals to ―ON‖ or ―OFF‖. It

can be like this: In MANUAL/AUTO mode, when emergency stop button is pressed, the standard emergency stop is executed, in addition, M74 user-defined command is also executed (it is executed only when there is already a M74 command in the system). This function is applicable to some special machine parts under the requirements of keeping some output signals ON while turning OFF some others. If any similar alarm occurs during the execution of M74, the execution stops. During emergency stop, if the M74 command is executed, and axis movement or tool change is being carried out, the system will stop M74 execution automatically.

2） In MANUAL/AUTO mode, when the parameter sets that M74 can be executed during

emergency stop (P412_d1=1), the pop-up window displays ―+M74‖. (When there is already a solidified M74 command in the system.)

3）For more details about M74, please refer to Chapter 8. 4）Please be careful when executing M74 function. It is only suitable for some special machine

tools.

【Relative parameters】

The external emergency stop signal function is valid when P404_d7 is set to 0. The external emergency stop signal function is invalid when P404_d7 is set to 1. P403_d3=0：When the emergency alarm is valid, the system only turns off the signals of spindle, cooling and lubrication. P403_d3=1：When the emergency alarm is valid, the system turns off all the output signals of the auxiliary function. P404_d7 is for debugging the system, and must be set to valid in the power-on state; otherwise,

Page 32

GSK96 Multi-function Position Control System User Manual

it cannot provide protection. P412_d1 parameter sets whether to execute M74 self-defined command during emergency stop.

4.1.4.4 Drive unit alarm

When the system is connected with the alarm output signal of a drive unit and appears Drive unit alarms, the system automatically closes all feed and prompts Z/X/Y drive unit alarms. All axes immediately stop motion, and the program stops running. At the moment, check the drive unit and relative device to troubleshooting and the system is turned on again. When there is the alarm in the course of motion, there may be great deviation between the coordinates displayed the system and the actual position, and the operator must correct the machine coordinates. In JOG working mode, the system prohibits all axes moving when there is the alarm. In AUTO working mode, the system prohibits the program starting run when there is the alarm. 【Relative parameters】 The drive unit alarm checks when P404_d5 is set to 0. P405_d4, P405_d3, P405_d2 separately sets alarm level of Z, X, Y drive unit.

4.1.4.5 Other alarms

When the system appears other alarms, Chinese characters prompts, at the moment, the operator can perform the troubleshooting based on PROGRAMMING, Chapter 6 Alarm Message.

4.1.4.6 Switching off power supply

The machine power supply is switched off immediately to avoid the accidence in the danger or other emergency cases when the machine is running. Note: When the coordinate axis is moving and the power supply is switched off, after the machine is

switched on again, there may be great deviation between the displayed coordinates and the actual position, and so the operator must execute the machine zero return or other ways to regulate the machine coordinates to ensure that the displayed coordinates are the same as those of the actual.

4.1.4.7 Reset operation

When the system outputs abnormally and the coordinate axis moves abnormally, the operator should

press to make the system be the reset state as follows:

1) All axis motions decelerate to stop;

2) Whether M function output is valid is set by P403_d2.

3) The automatic run ends, the modal function and state keep. 4）After the pressure low alarm occurs, press RESET key, the system will remove the alarm, and

Page 33

Operation Chapter Four System Operation

【Special attentions 】

1) The standard Reset function executed by the system is the function of turning on or turning off the

system output signals uniformly. The following function can be set: In Manual/Auto operation,

after Reset button is pressed, and the system executes the standard Reset function, the system

executes an additional M73 custom command (only when in Manual/Auto operation mode and

when there is a solidified M73 command in the system, the execution is available). This

function is applicable to some special machine components and is used when only some of the

output signals are required to turn off and some maintained. If there is an alarm occurs during the

execution of the M73 custom command, the execution is stopped.

2) In Manual/Auto operation mode, when the M73 custom command can be executed in Emergency

Stop state by setting a parameter (P412_d2=1), there is a prompt ―+M73‖ ( indicating the M73 is

being executed) added on the reset window (if there is a solidified M73 custom command in the

system).

3) For the programming, debugging and fixing of M73 custom command, please see Chapter Eight

―Custom Command Programming‖ in this manual.

4) Be careful to use M73 custom function during Reset. The function is only applicable to some

special machine tools.

re-clock to detect the pressure low alarm signal.

5）When the system is in G00，G97，G98 state, both F value and spindl analog voltage output

keep unchanged.

6）The system terminates the operation in progress, and returns the control to the initial interface

of the current operation mode.

【Relative parameters】

P403_d2=0: the system closes M03, M04, M08, M32 output signals when the reset key is pressed.

P403_d2=1: the system does not close M03, M04, M08, M32 output signals when the reset key

is pressed.

Parameter P412_d2 sets whether M73 custom command is executed during Reset.

4.2 CNC Working Mode Selection

The system uses the working mode key to directly select the all working modes. All working modes can direct switch to get the simple and convenient operations. The display is as Fig. 4-1 after the system is turned on, and the display state keeps till the other key is pressed to enter the EDIT working mode.

4.3.3 Part program communication

The communication of part programming includes the sending and receiving the part program. The sending mode is: the system outputs to U disc (CNC→USB) ; the receiving mode is: U disc inputs to the system (USB→CNC) Press hp2 in the program catalog search window, the system opens the U disc to enter the communication interface.

4.3.3.1 Sending part programs (CNC→USB) USB communication;

1） After entering USB communication mode, the system first checks whether a U disc has been

inserted. If no U disc is inserted, the system displays a prompt message box, prompting No USB device inserted . If a USB disc containing a folder named ―C001PRO‖ has been inserted, and there are CNCxxx.TXT files in the folder, the files will be listed on the USB file directory box. If there are no CNCxxx.TXT files in the C001PRO folder, the system prompts: USB device specified directory: C001 PRO has no programs. If the folder named―C001PRO‖does not exist in the U disc, the system prompts: No specified directory in USB device: C001 PRO

2） Output the part program stored the system to U disc as follows:

① Insert U disc in the system USB interface; ② The system automatically opens U file catalog(create a file in the U disc: C001PRO，file

format CNCxxx.TXT) . The system creates ―C001PRO‖ when there is no ―C001PRO‖ in the U disc root catalog.

③ In program search page, press key to input ：hp2 ; ④ Select the required programs to send according to the system hp1 help message.

⑤ Press ENTER to send and the system prompts to select the sending mode; ⑥ The system outputs the selected programs based on the selected sending mode and

displays the sending process till the sending is completed;

⑦ Select ESC to exit from U disc.

4.3.3.2 Receiving part programs(USB→CNC) USB communication;

1） After entering USB communication mode, the system firstly checks U disc, and opens

―C001PRO‖ existed in the U disc and lists ―CNCxxx.TXT‖ file.

2） Output part program stored in U disc to the CNC system as follows:

Page 39

Operation Chapter Four System Operation

① Insert U disc in the system USB interface; ② Press key to input：hp2 → Edit; ③ The system automatically opens U disc file catalog; ④ Select the required programs to receive according to the system hp1 help message; ⑤ Press ENTER to receive and select the sending mode according to the system prompt; ⑥ Input the programs according the selected receiving mode, display the receiving process

till the receiving is completed;

⑦ Select ESC to exit from the U disc.

【Note】

If the stored program name is the same as the sent program name, a prompt will be displayed

for you to determine whether to replace the original program or not. If you choose yes, the original program will be replaced by the received one.

4.3.3.3 TXT part program standard format in U disc

Use TXT, LST text to edit part program in U disc, but the file name must be compiled based on the standard format required by the system to be sent to the system as follow:

1) Name the file name of the part program to TXT or LST suffix, such as ―CNC008.TXT‖ in PC; it is suggested that the operator use TXT suffix to conveniently execute part programs on the PC.

2) The first line of TXT file content must specify the program number, its format is ―% XXX‖, i.e. percent sign follows the digit 1, 2 or 3, its range is 0~254, and the first line cannot have other content. Its range must be 0~254 because the program number created and stored by the system is 0~254, otherwise, the system cannot receive the programs and prompts the corresponding mistaken message. The program numbers received by the CNC are determined by the following method:

◆ The program number sent by the system USB is digit xxx of CNCxxx.TXT in―C001PRO‖ file folder in the U disc root catalog.

Note: in USB communication, the character string XXX digit of %XXX” in the first line should be the same that of xxx digit of CNCxxx.TXT. When they are different, the xxx digit of CNCxxx.TXT is taken as the standard.

3) The blocks start from the second block. The block must meet its format. Each block cannot exceed 250 characters, ends with the ENTER key, otherwise, the system prompts the error: Block too long in received programs.

4) The annotation area has Chinese annotation in the block.

5) Max. TXT file length cannot exceed the program stored space limit of the system.

6) You can refere to the part program file format that the system outputs to the U disc.

2) The system automatically creates the blank space when the letter or character following the digit (0~9) is input.

3) The cursor stays the position where the input is convenient after the character string is input.

4.3.4.1 Inputting program content

Note: P333 is set to 10 (the system automatically creates the block number, and the following is the same).

In program edit window, inputting the part program content is as follows:

① create a new program according to the operations of creating new part program; ② input one line content after the block N0000 is displayed; ③ press ENTER key after inputting one line programs to end the line input; ④ the system automatically creates the next block number and continuously input the program

content;

⑤ press ESC to complete the program content input after the last line programs are input.

【Note】

1） The first row of every line only displays the blank space; 2） Each block only displays 60 characters, and only the first 60 characters are displayed when

there are more than 60 characters, you can press to left move one character.

3） The serial number of the first row blank is 0, the last is 251, and the system only displays the

cursor instead of the character; there are up to 250 characters in the edit line; i. e. the first blank bit +250 characters+ the last cursor bit character=252.

4.3.4.2 Inserting program line Insert one or many program line between two program lines or in the front of the current block as

follows:

① Move the cursor to the first block end or the last block home of the two blocks; ② Press ENTER, and the system automatically creates a new block number between the

current block and the next (the serial number increment is P333 parameter 1/4 integer, the next block number can be modified when the above the increment is not enough) and remains a blank line.

③ Input the required block content; ④ After all content is input and many line are required to insert, ENTER is pressed, which is not

done when one line is required to insert.

【Example】

Page 43

Operation Chapter Four System Operation

Example: insert a new block M3 between N0020 and N0030 as follows: Move the cursor to the end of block N0020 or the beginning of block N0030; Press

ENTER key, and input M3.

4.3.4.3 Deleting a block Delete all content in one line as follows:

① move the cursor the home of the required line; ② press DELETE; ③ delete all content of the selected line.

4.3.4.4 Inserting a character in a block Insert a character in one block as follows:

① Press ALTER, switch the input mode to insert mode, i.e. the cursor is displayed to the down

② Move the cursor to the character following the required insert position; ③ Input the required insert content; ④ Insert the input content before the character pointed by the cursor.

【Note】

The CNC system requires there is a blank space between fields in the program line. In editing program, the system can automatically judge and create a blank space, but cannot automatically judge in the insert operation, and at the moment, the operator should input a blank to get the

complete program. 【Example】 Example: insert 1 between X and 0 in N0020 G0 X0.0 Z0.0. As follows:

The cursor moves the under 0 following X input 1 , displaying N0020 G0 X10.0 Z0.0

4.3.4.5 Deleting a character in a block Delete the content which is not needed as follows:

① Move the cursor to the character position which is needed to delete; ② Press DELETE to delete the character.

4.3.4.6 Modifying a block content Modify the content of the block into the new, which can be complete according the input

4.3.4.7 Program stored space For programs No. 0～252, No. 254, the system provides 400K memory space, so theoretically,

the size of a single program can be up to 400K. For No. 253 program, the system provides 4M FLASH memory space. 【Explanation】

1) The system displays the program leftover space and prompts the leftover stored space size.

2) When the current edit No. 0～252, No.254 program size are more than all stored space(max.

400K), the programs cannot be saved, and the system prompts the storage space has full: Overflow in edit area. Delete the old programs when the leftover space is not enough.

3) Max. edit space of No. 253 program is up to 4M, and is only saved to the system FLASH.

4) In saving programs, the program capacity is big and saving the programs need long time, and

the operator needs to wait.

When the system finds out the manual operation to cause the serious result, it closes the manual operation function and pops up the window display alarm message; the operator firstly modifies the parameter and then executes the manual operation according to the alarm message. The system provides many part program execution mode. The operator can execute many necessary settings in JOG working mode before run to get the safe machining process.

4.4.1 Coordinate axis movement

4.4.1.1 JOG movement

Press the system is switched from STEP or MPG mode into JOG mode. 【JOG TRAVERSE】is to keep pressing the coordinate axis move key, and the machine slider continuously moves; release the key, and the slider decelerates to stop. The traverse speed is

Page 51

Operation Chapter Four System Operation

executed according to the rapid speed or feedrate. However, the max. speed of Z, X, Y is limited by P100, P101, P102. Coordinate axis move key meanings are as follows:

X/Y/Z negative move key (it is X or Y when indicator is ON)

X/Y/Z positive move key (it is X or Y when indicator is ON)

◆ Z/X/Y coordinate axis switch: Press Z/X/Y SWITCH to the cycle switch of Z, X or Y operation; Z/X/Y SWITCH INDICATOR ON

indicates X or Y operation. The selected axis has been shown in the figure above. (when bit parameter P405_d1=1 and P405_d0=1, the machine tool has Y, X axis, then the switch is valid).

When the machine is switched into X (Y) operation, the program reference point return and the

machine zero return are valid in X (Y) axis. 【Note】

1) When the motor rotates with high speed and the feed key is released, the machine slider continuously moves and does not stop immediately because of the automatic acceleration/ deceleration. The movement length is determined by the max. motor speed, the acceleration/ deceleration time, and the feed override. The longer the acceleration/ deceleration time and the higher the speed is, the longer the distance between sliders are; on the contrary, the shorter the distance is.

4.4.1.2 Step movement

Press and the system is switched from JOG or MPG to STEP mode. 【STEP TRAVERSE】: press the coordinate axis move key and the machine slier moves the preset step width. The traverse speed is executed by the selected rapid or feedrate. However, the max. speed of Z, X, Y is limited by P100, P101, P102.

Press continuously the key, the machine slider will continuously feed the step width till the key is released and the slider has moved the last step width. The step width in the single step movement is displayed in the black background. The step width of single step movement is 0.001 0.01 0.1 1.0 10.0 50.0. the system can gradually select them according to STEP REGULATION.

【Note】

1) In STEP mode, press CYCLE PAUSE to stop slider moving. When the key is pressed down, the slider stops and the unfinished step will not be reserved.

4.4.1.3 MPG control

Press to switch from MPG mode to JOG or STEP mode, and the indicator ON means it is selected.

Page 52

GSK96 Multi-function Position Control System User Manual

【MPG movement】: the system receives the pulse signal generated by the manual pulse generator (handwheel or MPG) to control the movement of coordinate axis. The user can control the slight

movement of the coordinate axis by rotating the MPG.

◆ preset each movement of scale of MPG: The MPG dial rotates one case, and the coordinate axis moves one step width. The step width has

three gears: 0.001mm, 0.01mm, 0.1mm, which can be switched circularly according to the STEP REGULATION.

◆ preset MPG coordinate axis: Press MPG, then the coordinate of the selected coordinate axis is in the high light state.Then press

Z/X/Y/ SWITCH key to circularly select X, Y or Z as the axis controlled by MPG; Rotate MPG after the required coordinate axis is selected, and the selected axis moves according to MPG rotating. Rotate CW MPG and the coordinate axis moves positively. Rotate CCW MPG and it moves negatively.

【Note】

1) The MPG speed should be less than 5 r/s; otherwise, the motor will not stop even if the MPG stops, that will cause inconsistence in the slider movement distance and MPG scale.

2) In MPG mode, all the functions related to the axis moving including JOG or STEP movement function, program zero point return and machine zero point return are invalid.

3) In MPG mode, when axis movement related functions are executed, and the relative/absolute movement of field is input, MPG is forbidden temporarily and the LED flickers. After the above functions are executed, MPG function recovers automatically, and the other S, M, T auxiliary functions are valid.

4) When the bigger override (X 0.1 mm) is selected, the motor will rapidly traverse if the MPG is rotated rapidly. At the moment, because the system automatically accelerates/ decelerate, the motor will traverse not to stop although the MPG stops. The actual moving distance is determined by max. speed of motor, the acceleration/ deceleration time, the feedrate override and the MPG speed. The rapider the speed is, the longer the acceleration/deceleration time is and the rapider the MPG speed is, the longer the moving distance of motor decelerating is, otherwise the shorter the moving distance of motor is.

5) P400_d4=0: the step width 0.1 is valid; P400_d4=1, the step width 0.1 is invalid.

6) When P400_d1 is set to 1, the external MPG control button is valid, Y/Z selection axis, and the step regulation key are invalid.

4.4.1.4 Rapid traverse speed selection

◆ Manual rapid traverse and low feed state selection In JOG mode, the negative/positive movement speed of each axis can select rapid traverse and

cutting feed(low speed movement). Press to switch the rapid traverse and low speed feed states. The speed indicator ON is to select the rapid traverse state.

◆ Rapid override

Rapid override is divided into the four gears: 25%, 50%, 75%, 100%. increases to one gear till

100%. reduces one gear till 25%. Z (X, Y) actual traverse speed = P100 (P101, P102)x rapid override

◆ Manual operations influenced by rapid override and feed override are as followed: JOG MOVEMENT operation: when the speed indicator is ON, it is influenced by the rapid override;

when it is OFF, it is influenced by the feedrate override; STEP MOVEMENT operation: when the speed indicator is ON, it is influenced by the rapid override; When it is OFF, it is influenced by the feedrate override; INPUT FIELD MOVEMENT operation: when the speed indicator is ON, it is influenced by the rapid

override; when it is OFF, it is influenced by the feedrate override; Program reference point return operation: it is influenced by the rapid override; machine zero return operation: it is influenced by the rapid override; 【Note】

1) Firstly select the rapid override and press the coordinate axis movement key in JOG working mode.

2) Select the rapid override in STEP working mode, and regulate the rapid override in the course of movement, and the traverse speed changes.

4.4.1.5 Low speed feed speed selection

Press and the speed indicator is OFF, which is the selected low speed feed state.

◆ System embedding feedrate

When the input field F is 0, the system uses the embedding speed feed. The manual feedrate override has 16-gear 0%～150%, the corresponding embedding feedrate

of each gear is as follows:

【Note】

1) There is an error (2%) between actual speed and data in this table, and the actual speed should prevail.

2) When the feedrate override is 0, the system prompts ―Feedrate override is 0‖, which indicates

Page 54

GSK96 Multi-function Position Control System User Manual

the command is in execution state, and the machine slider is in stop state. The slider will move as soon as the override is adjusted to a non-zero value.

◆ Feedrate override

The manual feedrate override has 16 gears 0%～150% ; press and the feedrate override

increase one gear till 150%; press and the feedrate override reduces one gear till 0%.

4.4.1.6 Inputting field moving, setting feedrate In JOG working mode, the coordinate axis moves according to the input length and direction, or directly moves from the current position to the input coordinate position instead of the set step width as follows:

◆ Relative field of movement Corresponding operation of each coordinate axis:

X move_X field(X position), or U field(X relative movement) ; Y move_Y field(Y position), or V field(Y relative movement) ; Z move_Z field(Z position), or W field(Z relative movement) ; X, Z, Y, U, W, V range: -99999.999mm～99999.999mm;

Feedrate_F field (F0000～F15000，the leading zero can be omitted, unit: mm/min)

【Move field format】

Z(W)_ F_ ; Z moves, its speed is determined by the rapid/feed state when F is

omitted. (The same as in the followings.)

Y(V)_ F_ ; Y feeds Z(W)_ X(U)_ F_ ; Z/X feed simultaneously

【Note】

1) In JOG working mode, up to 2 axes move simultaneously at the currently selected manual

traverse speed.

2) X(U), Y(V) can be input when X, Y set by the system parameter are valid.

【Example 1】

Input: ：W MOVE W –5.2 ENTER RUN? START(or ESC cancel) ; it means Z negatively

5.2mm.

Input: ：X MOVE X 40 ENTER RUN? START(or ESC cancel) ; it means X negatively 40mm.

【Example 2】

Input: Z200 U50 ; Z moves to 200, X positively moves 50. its speed is not specified and determined by RAPID/FEED state. Input: U20 W-50 F80; X positively moves 20, Z negatively moves to 50. the feedrate is 80 and is influenced by the feedrate override. Input: F200; the set feedrate is 200. the system is switched into feed state. Input: F0; the set feedrate is 0, the system is switched into feed state and uses the embedded

speed.

◆ traverse speed explanation:

1) If no F field is input, it is the rapid traverse which is affected by the rapid override when the speed indicator lights up; and is the low speed move which is affected by the feedrate override when the indicator goes out.

2) When field F is input, the system will automatically switch to low-speed feeding state and the speed indicator is OFF; the gear of feedrate override is the current gear; when the speed is higher than P113, the speed set by P113 should prevail.

3) When the input F field is 0, the system will adopt the internal speed as the feedrate.

4) When the JOG or STEP is performed, it is under the control of F filed even when the speed indicator is OFF.

5) Under the condition that no F field is input, when the speed indicator is ON, the movement is rapid traverse and affected by the rapid traverse override; when the indicator is OFF, the movement is low-speed traverse and is affected by feedrate override.

6) When the indicator is OFF, the speed of low-speed traverse is limited by P113 (maximum cutting feedrate); when the speed is higher than P113, the speed set by P113 should prevail.

7) When the indicator is OFF, the movement and AUTO mode of two-axis feed is the same as G01 (interpolation feed). These two axes move simultaneously at a proportional speed and stop at the same time. F is the resultant speed of the two axes.

8) When the indicator is ON, the movement speed of single-axis feed is determined by parameters P100~P102 and rapid traverse override.

9) When the indicator is ON, the movement of two-axis rapid traverse is determined by P400_d3, and it is the same to the execution of G00 in AUTO mode. When P400_d3=0, the movement is performed separately. The resultant speed displayed on the screen is larger than the maximum rapid traverse speed of each axis. When P400_d3=1, the movement is in interpolation mode and these two axes move simultaneously at a proportional speed and stop at the same time. The movement parameters and slope of the distance will be taken into consideration so as to ensure that there is no stall during the movement. Different slopes may correspond to different rapid traverse speed.

10) When the feedrate override is 0, and the system is in low-speed feeding mode or F field exists, movement is forbidden. Press ENTER, a prompt ―feedrate override is 0‖ will be displayed till the override is adjusted to other value.

11) The input of F field is specified by G98 command; G99 command cannot be input in the system.

◆ Call field execution The system automatically saves the last 8 times executed command record in inputting field moving.

Press , and the system pops up the window list record; the operator can input according to the digit serial number to modify or directly execute the operation.

4.4.1.7 Drive unit enabling control Set P416_d4 to 1, continuously press DELETE in JOG and AUTO mode, and the drive unit is closed and the motor is in free state. Press DELETE in the drive unit closing state, and the drive unit is started, and the motor is in working mode.

4.4.1.8 Coordinate axis motion alarm prompt In executing the axis motion, when the current motion axis meets the tool nose coordinate software limit points(tool nose software limit point), the axis cannot continuously move and moves reversely, and the system displays the alarm prompt. When the axis meets the machine coordinate software limit point, it only moves reversely. But the manual zero return function is not control by the software limit value range.

【Note】

In JOG or STEP mode, when the moving axis reaches the soft limit, soft limit alarm is prompted. When single-axis movement is performed in STEP feed mode and field input move mode, the axis will not stop neither until the soft limit is reached if the increment is large, then the system prompts limit alarm message. When the Z/X/Y axis movement is commanded by input fields, if the setting value exceeds the range, limit alarm message is displayed and the execution is inhabited. Whether machine soft limit alarm and tool nose soft limit alarm is enabled is set by P404_d4, P404_d3.

4.4.2 Creating coordinate system

4.4.2.1 Creating machine coordinate system_machine zero return(machine reference point return)

◆ Machine zero: Machine coordinate system fixed on the machine is the reference coordinate system for CNC

counting the coordinate position. After the system is installed, the operator should firstly create the machine coordinate system. The reference point of the machine coordinate system is called machine zero(or machine reference point or machine zero). Some fixed point on each machine is taken as the machine reference point, and the system firstly returns to the machine zero and then returns to the machining starting point to eliminate the machine coordinate system deviation caused by the power-off and step-out; executing the zero return instead of tool setting again after power-off accidentally can find the machine coordinate system and workpiece coordinate system to continuously machine the workpiece. In most conditions, the system looks for the machine reference point by the deceleration switch and zero switch installed on the machine; or by the one-turn signal of servo motor as the zero signal only with the deceleration switch. The deceleration switch is generally installed near to the max. travel of positive Z/X//Y coordinate axis.

◆ Machine zero return operations:

Press , and Z (Y or X) execute the machine zero return; (Z/X/Y switch indicator lighting means

Y or X operation) Z (Y or X) moves to Z（Y or X）machine zero at the selected rapid traverse speed in the zero return direction.

Page 57

Operation Chapter Four System Operation

◆ Zero return process as follows: Zero return mode 1: when there is the deceleration signal and zero signal, the system executes

the zero return mode 1; the zero return process is as follow:

Step 1: the coordinate axis moves to the specified direction at the rapid speed till the block

presses down the deceleration switch and the system has checked the starting point of the deceleration signal to decelerate to stop moving;

Step 2: the coordinate axis reversely moves at the set zero return speed till the system has

checked the starting point of deceleration signal to decelerate and to stop moving;

Step 3: when the set zero offset is not zero, the system continuously moves one zero offset

value;

Step 4: the coordinate axis continuously moves at the set zero return speed, and starts

checking the zero signal till the system has checked the zero signal to decelerate to stop moving;

Step 5: the above operations have completed the zero return motion and check processes;

at last, the system automatically modifies the current machine coordinate into the ―Zero coordinate‖ set by the parameter.

Zero return mode 2: when there is the only deceleration signal without the zero signal, the

system executes the zero return mode 2. Because there is no zero signal, the system reduces the above the Step 3 and Step 4 compared to the zero return mode 1; the system only executes the above Step 1, Step 2 and Step 5 to complete the zero return process, which zero return precision is worse than the zero return mode 1.

Zero return mode 3: when there is the zero signal without the deceleration signal, the system

execute the zero return mode 3. Because there is no deceleration signal, the system reduces the above the Step 1, Step 2 and Step 3 compared to the zero return mode 1; the system only executes the above Step 4, and Step 5 to complete the zero return process. In the mode, the manual operation moves the coordinate axis to a special position and then the system executes the zero return, otherwise, the result is not correct.

Zero return mode 4: the system executes the zero return mode 4 when there is neither

deceleration nor zero signal. When there is no machine zero check device installed on the machine, the relative parameters are set to 0; at the moment, when the system executes the machine zero return function, it does not check the zero signal and deceleration signal till it returns to the zero coordinate position of the axis.

【Note】

1) The direction of machine zero return points to the zero-return direction, if this direction is positive, then, the axis should in the negative direction.

2) In the machine zero return, the rapid traverse speed of the coordinate axis is controlled by the rapid override.

Page 58

GSK96 Multi-function Position Control System User Manual

3) In the machine zero return, the coordinate axis motion is not limited by the software limit parameter.

4) Parameter related to the machine zero return is referred to OPERATION, Section 4.6.4.2.

5) Connection related to the machine zero return and zero return mode are referred to CONNECTION, Section 3.3 Machine Zero Function and Connection.

6) After the system executes the machine zero return, the blue icon of the machine zero return after the corresponding machine coordinates are displayed as the prompt.

4.4.2.2 Creating machine coordinate system_without machine zero(no machine reference point) (Prompt: the coordinate axis with the zero check device cannot execute the operation.)

The coordinate axis without the zero check device(without deceleration signal and zero signal), can create the machine coordinate system as follows:

【Format】

Input: INPUT U NEW COORDINATE VALUE ENTER. The current X machine coordinate is modified into the new coordinate value. Input: INPUT V NEW COORDINATE VALUE ENTER. The current Y machine coordinate is modified into the new coordinate value. Input: INPUT W NEW COORDINATE VALUE ENTER. The current Z machine coordinate is modified into the new coordinate value.

4.4.2.3 Setting workpiece coordinate system The system uses the floating workpiece coordinate system. The workpiece coordinate system is the reference to tool setting and relative dimension. After the machine coordinate system is confirmed, the workpiece coordinate system should be set. 【Format】

Input: INPUT X NEW COORDINATE VALUE ENTER. The current X tool nose coordinate is modified into the new coordinate value. Input: INPUT Y NEW COORDINATE VALUE ENTER. The current Y tool nose coordinate is modified into the new coordinate value.

Input: INPUT Z NEW COORDINATE VALUE ENTER. The current Z tool nose coordinate is modified into the new coordinate value.

◆ Actual operation steps of setting workpiece coordinate system are as follows: Install the trial cutting workpiece on the machine and select any one tool( generally use the first

tool in the machining).

1. Setting X workpiece coordinate:

1) Select the proper spindle speed and start the spindle.

2) Traverse the tool to cut a little sidestep on the workpiece, and X does not move.

3) The tool in Z direction moves to the safe position, the spindle stops rotating. The system

Page 59

Operation Chapter Four System Operation

measures the diameter of cut sidestep.

4) Press INPUT and the system displays SETTING, and press X and the system displays Setting Workpiece Coordinate System X, the operator inputs measured radius value(radius programming); press ENTER, and the system automatically sets X workpiece coordinate.

2. Setting Z workpiece coordinate:

1) Start the spindle, traverse the tool to cut a little sidestep on the workpiece. X does not move.

2) Move the tool to a safe position along with X direction and stop the spindle rotation.

Select a point as a reference point (a fixed point on the machine is better, for example, the

chuck surface or other reference plane, so that the new workpiece coordinate system overlaps on the original workpiece coordinate system). Then, measure the distance from the cutting surface to the selected reference point in Z direction.

3) Press INPUT, and the system displays SETTING, press Z and the system displays

SETTING WORKPICE COORDINATE SYSTEM Z, input the measured data and press ENTER, the system automatically set Z workpiece coordinate.

Note: The system workpiece coordinate system has been created after the above operations are

completed.

【Explanation】

1) Setting the workpiece coordinate system operation only modifies the tool nose coordinates of

current point without changing the offset and the machine coordinates. The operation result is that the offset between the workpiece coordinate system and the machine coordinate system is set again.

2) Setting the workpiece coordinate system operation is executed once and is not set later after

the system is initialized or the workpiece type is changed(all offset values are cleared to zero).

【Note】

When the actual position of the tool is inconsistent with the one of the workpiece coordinate system due to the step out caused by some special causes, it is inappropriate to use the method of resetting the workpiece coordinate system, because both workpiece coordinate system and machine coordinate system are changed after step-out. In this case, if only the workpiece coordinate system is corrected, without correcting the machine coordinate system, an unexpected “machine coordinate soft limit alarm” may occur.

Proper operations after motor stepping-out as follows:

1) Select the reference point (the tool nose easily reaches and the operator can conveniently observe it ) for one couple of tool, measure Z, X coordinates of the point.

2) Move the tool nose to some reference point(the known reference point coordinates);

3) Continuously press twice DELETE and close the drive unit when the tool nose coordinates are

not consistent with the reference point coordinates;

4) Input the field to move and make the tool nose coordinates be consistent with the reference point coordinates(the coordinates change and the actual tool nose does not);

5) Press DELETE to start the drive unit.

Page 60

GSK96 Multi-function Position Control System User Manual

So, the machine coordinate system and the workpiece coordinate system are corrected simultaneously.

4.4.2.4 Setting program reference point In the machine coordinate system, the operator should confirm one position where the tool change can be executed safely when the tool post stops here, and where the workpiece is installed conveniently. The program reference point can be set when the tool post stops at the position which is called the program reference point(Program zero). The program reference point coordinates are relative to the machine coordinate system. 【Format】

Press INPUT and the system displays SETTING, press 0 and the system displays Setting program reference point?, at the moment, press ENTER, the system confirms Z/X/Y to be the program reference point.

When the operator sets again the workpiece coordinates after setting the program reference point, the previous reference point coordinates do not change in the new workpiece coordinate system, at the moment, the operator should set again the program reference point. The initial value of the program reference point is X=150 Z=150. After the operator sets the program reference point, the program reference point return command G26 and the program zero return operation by the system panel return to the point no matter what the machine slide stops anywhere.

4.4.2.5 Program reference point return

Must confirm the program reference point position before the operator executes the program reference point return, otherwise, the unexpected result brings.

In JOG working mode, the operator directly press the function key to execute the operation. After the key is pressed, the corresponding coordinate axis rapidly returns to the program reference point.

When the Z/X/Y axis change indicator lighting means X or Y is being executed By pressing key, Z (Y or X) rapidly returns the Z (Y or X) program reference point from the current point. (the Z/X/Y axis change indicator lighting means X or Y is being executed ) . 【Note】

1) Generally, each axis should stop at the program reference point in waiting for the machining.

2) After the system executes the program reference point return, the green icon of the program reference point return before the corresponding machine coordinates are displayed as the prompt.

4.4.2.6 Recovering the workpiece coordinate system and program reference point

In JOG working mode, the workpiece coordinate system and the program reference point have been set. In AUTO working mode, when all executed blocks include G50, the workpiece coordinate system

Page 61

Operation Chapter Four System Operation

and program reference point have been changed. The operator can use the following operations to recover the workpiece coordinate system and program reference point set in JOG working mode. 【Format】

Input: G 5 1 ENTER. Recover the workpiece coordinate system and program reference point

set in JOG working mode.

4.4.3 Spindle control function

4.4.3.1 Spindle starting/stopping control

◆ Spindle starting/stopping as follows: In JOG working mode, the operator can directly operate the function keys on the panel or input M03/

M04/ M05 to control the spindle rotation (CW/CCW) and stop). (feed/spindle hold is invalid in JOG working mode).

Press or input M 3 ENTER; the spindle rotates CW. The system displays the spindle state and LED lights.

Press or input M 5 ENTER; the spindle stops rotation.

◆ Spindle JOG control The spindle stop key can switch the spindle JOG control state.

In the spindle stop state, press and the Spindle state icon is displayed in the highlight on

the screen and the system is switched to the spindle JOG control state. Press again, the

system is switched to the normal-regular state. In the spindle manual state, press , the spindle rotates at the specified speed in the specified time and then stops. (when the specified time is too

long, the operator can press to stop the rotation). In the spindle manual state, MDI inputting the spindle control command M03, M04, M05 are invalid. The spindle manual speed is specified by P309, the manual rotation time is specified by P308, and the spindle stops and LED indicator is OFF when the manual time ends. When parameter P308 is 0, the spindle JOG function is disabled.

◆ Interlock between the spindle starting/stopping and chuck: P402_d5=0: interlock relationship between the hydraulic chuck control and the spindle control

1) When the chuck clamps, the system forbids starting the spindle; otherwise, the system alarms ‖The chuck clamps and the system forbids starting the spindle‖.

2) When the spindle rotates CW, the system forbids the chuck operations, otherwise, the system alarms ―The spindle does not stop and the system forbids operating the chuck‖.

◆ Interlock between the spindle starting/stopping and tailstock:

P402_d3=0: Interlock between the tailstock control and the spindle control: The system forbids operating the tailstock when the spindle is rotating; otherwise, the system

alarms ―The spindle does not stop and the system forbids operating the tailstock‖.

2) When the gear controls the signal code output (P410_d5 is set to 1) and the controlled lines specified by P310 are less than 4, only the low gear control is valid, and the high code control is released and is not controlled by the gear.

3) When P410_d5 is set to 0, the gear control signal directly outputs by the bit, S range is S00～ S04. One gear signal corresponds to one gear signal. S0 means all output is invalid.

4) When P410_d5 is set to 1, the gear control signal outputs in code, S range is S00～S15. The detailed code output is as follows:

Note: “★” in the above table means the output of the corresponding output point is valid.

◆ Execution process and signal output time sequence of spindle S gear shifting:

When the system is turned on, it defaults S00, S01～S04 output are invalid. When the system

executes any one of S01, S02, S03, S04, the corresponding S signal output is valid and keeps, and at the same time, the output of other 3 signals is cancelled. When the system executes S00, it cancels S01～S04 output and one of S01～S04 is valid.

4.4.3.3 Spindle S_ speed control (Prompt: it is not necessary to read the chapter for the operator using the frequency spindle.)

When the machine uses the frequency spindle, P410_d6 is set to 1. To resolve the converter with low torque, the system should 4-gear automatic gear shifting output signal to match the converter working in the high frequency to make the machine get the low speed and big cutting torque. The system uses M41/M42/M43/M44 to control the spindle gear control; S controls the spindle speed.

【Explanation】

1) M41, M42, M43, M44 output gear control signal. Each gear signal corresponds to one output point S01, S02, S03, S04.

2) Actual output controlled lines of spindle gear are specified by P310. P310=4: actual output controlled point are S01, S02, S03, S04 ; P310=3: actual output controlled point are S01, S02, S03; the system releases S04 as

other use.

P310=2: actual output controlled point are S01, S02,; the system releases S04, S03 as

other use.

P310=1: actual output controlled point are S01; the system releases S04, S03, S02 as

other use.

P310=0: actual all point doe not output; the system releases S04, S03, S02 , S01 as other

use.

3) The initial gear state of the system ON is M41.

【Execution process and signal output time sequence of spindle M gear shifting:

When the CNC is turn on, it states is controlled by P400_d6 (spindle gear memory) to whether it

memories the spindle gear or not.

1) When P400_d6 is 0, the system is turned on after it is turned off, the spindle gear is not memorized and the system default the 1st gear of the spindle, and M41～M44 do not output;

2) When is P400_d6 is 1, the system is turned on after it is turned off, the spindle gear is memorized.

The system does not execute the gear shifting when the specified gear is consistent with the

current gear. If not, the system executes the gear shifting as follows:

① Execute one of M41, M42, M43, M44, the value (unit: millivolt)set by P314 (output voltage in

the spindle gear shifting) is output to the analog voltage to the spindle servo or the converter.

② The system closes the previous gear output signal after it delays P311 (frequency spindle

gear shifting time 1) ;

③ The system outputs the new gear signal after it delays P313 ( frequency spindle gear shifting

interval time);

④ When the system is connected with the checking gear shifting in-position input signal M41I,

M42I, M43I, M44I, and the gear shifting is not in-position, it always waits the gear shifting in-position signal to execute the next step; when the system is not connected with the checking gear shifting in-position input signal and directly executes the next step; M41I～

M44I input signals are defined by the interface parameters;

⑤ The system delays P312 (frequency spindle gear shifting time 2), and outputs the spindle

analog voltage according to the current gear based on P300～P303 (corresponding to gear 1～4), and the gear shifting ends.

◆ Speed control of frequency spindle When the machine uses the frequency spindle, S controls the speed. The spindle standard

Page 65

Operation Chapter Four System Operation

format consists of S+4-digit digital, 2-digit means the spindle gear number. There are 2 methods to input the spindle speed input.

1) S sets the fixed speed of the spindle (r/min); when S is not changed, the spindle speed is not changed, which is called Constant speed control.

2) S sets the tangent speed(m/min) of the tool relative to the workpiece outer, which is called constant surface speed control. In the constant surface control, the spindle speed changes as X tool nose coordinate value changing in cutting feed. The detailed is referred to

PROGRAMMING Constant Surface Control G96, Constant Surface Speed Control Cancel G97.

【Command format】

G96 ; set the constant surface speed cutting state; G96 S__ ; set the constant surface speed cutting state and specify the surface value;

range: 0～9999 m /min; G97 ; cancel the constant surface state; G97 is modal G97 S__ ; cancel the constant surface state and specify the speed value; range: 0～

9999 r /min; S__ ; It is determined by the current state; it can be speed value or surface

speed value cutting.

【Operation example】

Input: S 2 0 0 ENTER; the system switches the speed into 0～10V analog voltage to output the converter. 【Explanation】

1) In executing S, the system takes the max. spindle speed value of the current spindle gear as the reference, counts the analog voltage value corresponding to the specified speed, and then outputs to the spindle servo or the converter.

2) To make the spindle actual speed be consistent with the speed set by S, P300～P303 should

set the actual max. spindle speed value(output analog voltage is 10V) of each gear; the setting method: input S_ according to the setting value of P300～P303, and modify P300～ P303 setting according to the actual displayed spindle speed value.

3) When the system is turned on, the analogy voltage output is 0v, the system outputs

corresponding analog voltage value after it executes S; it always keeps later(except for the cutting feed state in the constant surface speed control and X coordinate value is not changed). After S0 is executed, the analog voltage output is 0V. CNC resets in the emergency stop, the analog voltage output keeps.

4.4.3.4 Servo spindle working state setting The system switches the spindle working mode when the spindle uses the GSK DAP03 servo drive unit.

【Relative parameter】

The function is valid when the controllable axis has Y, P410_d4 (relationship between the spindle and Y): it is not switched when it is 0, which means the spindle operation is not related to Y; it is switched when it is 1, which means the spindle operation is related to Y operation, and is interlock but they cannot be operated simultaneously. When the spindle is switched into the position control mode(P410_d4=1) , the spindle speed is controlled by Y feedrate, S is ignored in machining in AUTO working mode, executing S prompts the execution is mistaken in JOG working mode. M47/M48 is valid when P410_d4 is set to 1.

◆working mode setting operations between the spindle and Y: In JOG working mode, the operator can input M47/M48 to set the working state between and the

spindle and Y.

Input: M 47 ENTER ; set Y permissive working mode. It can be operated when the spindle is in

stop state, otherwise, the system alarms.

Input: M 48 ENTER ; set Y forbidden working mode. It can be operated when the spindle is in

stop state, otherwise, the system alarms.

When the system executes M47, it outputs APO level signal and checks API signal; when API level is ―0‖, the system set Y working mode, displays Y operation icon ; in the state, the system permits Y

motion operations, forbids the spindle start/stop (M03/M04/05 is invalid and the system prompts the alarm message). When the system executes M48, it outputs APO signal and checks API signal; when API level is ―1‖,

the system set spindle working mode, disappears; in the state, the system forbids Y motion operations, permits the spindle start/stop (Y motion in AUTO working mode causes the alarm). The concrete connections of APO and API signals are referred to CONNECTION.

【M47Note】

1）After the system executes M47, press STOP EMERGENCE, the system will exist M47 status, andit

is no use to press RESET.

2）When the system is executing M47, press RESET,or STOP EMERGENCE, he system will exist

M47 status.

4.4.4 Cooling control

In JOG working mode, directly operate the function on the panel or input M08/M09 to control the cooling ON/OFF.

Press to switch cooling ON/OFF; the State icon on the screen and LED indicator indicate its corresponding state.

Input: M 8 ENTER ; cooling ON. Input: M 9 ENTER ; cooling OFF.

t1：in pulse control mode, M08, M09 output hold time is set by P326.

【Relative parameter】

P410_d7: P410_d7=1: the system pulse output controls the cooling; P410_d7=0: the system level output controls the cooling. The bit parameter shares with the spindle controlling output bit parameter.

4.4.5 Manual tool change control

The system has up to 16 tool positions. It selects the tool change control process by setting the tool post type parameter (the system has no the integrated function of the electric tool post on the machine). The tool post type parameter P318 is 0～8, and the machine is equipped with the line-up

tool post; when the tool post parameter P318 is set to 0, the tool change operation is not performed; When set to 9, the system calls M60 command to execute the tool change.

◆ Input format of T command The standard format of the tool function field consists of T+4-digit, the first 2-digit is the tool number,

and the second 2-digit is the tool offset number. It is not necessary to input the complete 4-digit or to use the 2~4-digit. 【Format】

Txx ____ the first 1-digit is the tool number, the second 1-digit is the tool offset number; Txxx ____ the first 1-digit is the tool number, the latter 2-digit is the tool offset number; Txxxx ____ the first 2-digit is the tool number and the second 2-digit is the tool offset number.

【Explanation】 Tool number range is decided by P319 (max. tool number: 1～16; when P319 is 4, the tool number range is 0～4. The input tool number is 0, which means the system keeps the current tool number.

The offset number range: 0～64; the input tool offset number is 0, which means the system cancels the offset. 【Example】

Key in： T 4 6 Enter ；Changing to tool No. 4, and executing tool offset No. 6

Page 68

GSK96 Multi-function Position Control System User Manual

Key in： T 0 6 Enter ；Maintaining the current tool No., and executing tool offset No. 6 Key in： T 0 0 Enter ；No tool changing, and canceling tool offset Key in： T 0 4 0 Enter ；Maintaining the current tool No., and executing tool offset No. 40 Key in： T 4 0 5 Enter ；Changing to tool No. 4, and executing tool offset No. 5 Key in： T 0 6 0 8 Enter ；Changing to tool No. 6, and executing tool offset No. 8

【Note】

1) Example: inputting T400 means the system executes No. 4 tool change and cancels the offset.(note: cannot input T040).

2) Set P318 to 0, and there is no tool change signal output in selecting the line-up tool post.

3) When the tool change is failure or is interrupted in the tool change(reset, emergency stop), the

system confirms the tool is in the unconfirmed position and prompts the tool number flashing in red, at the moment, the operator cannot start the machining program; the system can recover the normal state when it executes one successful tool change operation and it is turned on again.

4) For the tool change mode of M60 self-defined command, refer to Section 3.4 Tool Change

Control Function and Connection in this manual.

4.4.6 Manual tool setting operation

Machining one workpiece needs several different tools. Because of the tool installation and tool shape deviation, its tool nose position is not complete consistent and has some offset when each tool rotates to the cutting position, Tool setting is called that the system automatically memorizes the Offset to the specified tool Offset number. After the tool setting, the operator is only based on the part drawing and machining technology to compile the workpiece program without considering the tool deviation, and only specifies the corresponding Offset number in the tool change in machining program. The offset table can record 64 groups of tool offset, each tool offset number corresponds to one group from 1～64. Each group separately records Z offset, X offset, Y offset (Refer to OFFSET working

mode when there is X or Y.) Through tool setting, the system will modify Z offset, X offset, Y offset of the specified tool offset number. 【Notes before tool setting】

1) According to the above, confirm the Offset to the Offset number, and confirm the content of Imaginary tool nose number in advance.

2) For the same tool nose, memorize Z offset value and X offset value to the same one offset

number, otherwise, it causes the serious result.

3) Generally, it is better to use the sequence for No. 1 Offset number with No. 1 tool, No. 2 Offset number with No. 2 tool, which is convenient to memorize them.

Page 69

Operation Chapter Four System Operation

4) Firstly execute the Offset number, and then tool setting. Example, firstly execute the T49 command when the system memorizes the Offset in No. 4 tool to No. 9 Offset number.

5) The system executes the tool setting when the workpiece coordinate system is normal,

otherwise, the result is not correct.

The system has the trial cutting tool setting as follows:

4) Press I , and the system displays Tool setting X ; input the measured diameter vale and press ENTER.

5) The system prompts Confirm tool offset number：XX ; it automatically presets one offset number, and the operator directly presses ENTER when the offset number is

consistent with the input. Otherwise the operator presses ENTER after inputting offset number. The system automatically counts X tool offset value and stores it to the specified offset number.

2. Z tool setting:

1) Start the spindle again, traverse the tool to cut a small sidestep of the workpiece.

2) Z does not move but X does to the safe position, and stop the spindle.

3) Select one point as the reference point, measure Z distance from the cut end face to the

selected reference point.

4) Press K and the system display Tool setting Z to input the measured data, and press ENTER.

5) The system prompts Confirm tool offset number：XX ; it automatically presets one

4.5.1 System working mode in AUTO working mode

In AUTO working mode, the system is in several mode according to execute workpiece programs; when the system is in different states, it permits the functions are different; there are several states as follows:

Initial state: it is the execution pointer of the program points to the first line but the system has not

executed; the system is just now switched from other mode to AUTO Working mode to enter the initial state or returns the initial state after the program is executed or the

system alarms. Run state: the system is executing the block and the coordinate axis is moving. Pause state: the current block has not executed completely in the course of executing the axis

motion command to pause; the system waits the operator presses the key to execute

the operation.

Block stop state: the current block has been executed and the next has not executed, the system

waits the operator presses the key to execute the operation.

4.5.2 Function key operation in AUTO working mode

4.5.2.1 SINGLE execution and CONTINUOUS execution switch SINGLE execution and CONTINUOUS execution switch:

Press and the system switches SINGLE/CONTINUOUS circularly; (it is valid in any states).

In continuous execution, press the key and the system switches to SINGLE working mode, after the current block is executed, the system stops, and continuously executes after CYCLE START is

pressed. In CONTINUOUS working mode, press CYCLE START, and the program is executed from the beginning to the end. In SINGLE working mode, press CYCLE START key once and the system executes one block (for the

Page 81

Operation Chapter Four System Operation

cycle command, the system only executes one operation; press CYCLE START, and the system executes one operation).

4.5.2.2 Dry run and machining run switch Check all content of machining programs in dry run, which can ensure the machining workpiece is not

discarded because of some programming data error in the program. Dry run/ machining run switch

Press , and the system switches dry run/automatic machining run mode

In DRY working mode, whether M, S,T is valid is set by the parameter, coordinates of each axis

automatically recover the previous before the Dry working mode.

Relative parameters in DRY Run working mode:

P401_d7：

0：When the system executes the miscellaneous command, it must output the signal, check the

signal, which is the same that of the normal machining.

1：The system does not output the signal or check the signal when the system executes the

miscellaneous command.

P401_d6：

0：The execution speed of feed command is set by the program, which is the same that of the

normal machining.

1：The execution speed of feed command is not set by the program, max. speed (P113) of cutting

feed displays the program path.

【Note】

1) The dry run key is valid when the program is executed in the initial state. In the course of program execution, the key is invalid and cannot be switched when the program does not end and the system has not exited the execution state.

2) P401_d7=0: in DRY RUN working mode, all miscellaneous command M, S, T are executed; the system recovers to the previous state when it exits from the dry run state.

3) P401_d7=1: in DRY RUN working mode, the system does not output and check the signal when it executes the miscellaneous function; when the system executes T function, the tool offset number is executed (when the previous is T11, it becomes T13 after T33 is executed), the system recovers to the previous after it exits from the DRY RUN working mode.

4) In DRY RUN working state, all macro command and M60～M74 are normally executed; after the system modifies the offset and the system exits from the DRY RUN working mode, the tool

nose coordinates of corresponding tool offset number are changed.

5) The workpiece counter does not automatically add 1 in DRY RUN working mode.

4.5.2.3 Running a part program from the first block After entering AUTO working mode, the system enters the initial state, and the program pointer points

Page 82

GSK96 Multi-function Position Control System User Manual

to the first block of the current program, and CYCLE START key is pressed to start the program to automatically run. The being executed block displays and flashes in poor color; the first line is the executed block, and the 3rd line is to be executed; when the machining program is the conditional command, the skip or call target is not well-defined, and the 3rd line may not be displayed.

4.5.2.4 Running a part program from a specified block In some special conditions, it is necessary to start to run from some block in a part program. This system allows starting any one block of current part program. (it is valid in initial state) Steps to select a block:

1) Press INPUT, and the system pops-up the program browse window, displays the current program and the pointer points to the first block of program.

2) Pressing , , , , and the system displays the content of the top(down)

block or up(down) page. Press ESC and the system exits from the selected and displays the previous block.

3) When the pointer points to the required block, ENTER is pressed and the system prompts ―Run?‖

to wait the next execution.

4) At the moment, press CYCLE START and the system executes the program from the block

pointed by the pointer; press ESC and the system exits the selection and the pointer points to the first block.

【Note】

1) The specified block cannot be in canned cycles, compound cycle bodies or subprograms, otherwise there is the unexpected run. The system selects G00 or the tool change command before G00.

2) When the system runs the program from the specified block, the selected block should be the linear movement or S. M. T.

3) In the course of program execution, press INPUT and the system pops-up the browse and

forbids executing the selected block.

4.5.3 Displaying in a part program running

When the part program is running, this system displays the running state, the dynamic run coordinate, the workpiece planar solid graph, and the path of tool nose in the course of program running, which is very convenient to monitor the running state of the machine and the program. The display as follows:

 The dynamic coordinates or the dynamic tool nose movement path graph or workpiece

contour graph.

 Current block content.  Spindle, cooling, lubricating, tool, speed, chuck, tailstock, and machine miscellaneous

Page 83

Operation Chapter Four System Operation

function state.

 Feedrate override, rapid override.  Machining time, workpiece count.

4.5.3.3 Machining workpiece count and timing Workpiece count: when the program being executed once means the program ends (M02, M20,

M30), the machining quantity count adds 1, and max. count range is 99999, and the count becomes 0 when it exceeds the max. When the program ends with M99, the machining quantitity also increases by 1 after the program is executed once.

Machining time: record machining program execution time. When CYCLE START is pressed

and the system executes the program, the timing does not end till the program ends. In running, the system pauses, and at the same time, the timing stops. In SINGLE working mode, the system only records the run time of each block. The system displays max. machining time range: 99 hours, 59 minutes and 59 seconds. When the machining time reaches the max. value, it automatically becomes zero and continuously runs program and executes the timing again.

Workpiece count and machining time clearing: in initial state, continuously press twice and

the workpiece count clears; continuously press twice, and the machining time clears.

4.5.4 Manual operation of miscellaneous function

In AUTO working mode, press function keys to execute some miscellaneous function

operation of the machine, and the other functions are the same in JOG working mode.

1) Cooling ON/OFF is valid in any states.

2) When P400_d5 is set to 0, spindle CW, CCW, stop key are valid:( invalid in run state).

3) In initial state, when the hydraulic chuck control function is valid, the external button or foot switch controls the hydraulic chuck clamping/releasing which interlocks with the spindle.

4) In initial state, when the hydraulic tailstock control function is valid, the external button or

foot switch controls the hydraulic tailstock forward/backward which interlocks with the spindle.

4.5.5 Speed override tune in AUTO working mode

4.5.5.1 Speed override tune In AUTO working mode, the feedrate override and rapid override keys in any state are valid. In AUTO working mode, the system can set the speed without changing the program and parameter. Change the program running speed by changing the speed override.

● Feedrate override speed word F setting value in tuning the program: Actual feedrate speed = Fx feedrate

The feedrate override has 16 gears 0%～150% (increment of 10%), all commands controlled by

Page 84

GSK96 Multi-function Position Control System User Manual

the feedrate is controlled by the feedrate override.

● Rapid override G00 rapid traverse command speed in tuning programs.

Z (X or Y) actual rapid traverse speed = P100 (P101, P102)×rapid override

The rapid traverse override is divided into 25%, 50%, 75%, 100%. All rapid traverse commands and the operations are controlled by the rapid traverse override.

Whether programs are running or not, pressing rapid override +/-, feedrate override +/- keys can change the speed override. The actual traverse speed of the machine slider changes if the speed override is changed when the programs are running. In program running, the program stops running when the feedrate override is 0, the system prompts: Feedrate override be zero. The program continuously runs when the feedrate override is not zero.

4.5.5.2 MPG speed control In AUTO working mode, using MPG controls rapid/feedrate override. P402_d1=1: MPG controlling rapid/feedrate override is valid, and the actual feedrate and the rapid speed are as follows:

Actual feedrate= F x feedrate override x MPG override

Z (X, Y) actual rapid speed = P100(P101, P102) x rapid override x MPG override MPG override range：0% ~ 100%. MPG controlling rapid/feedrate override:

◆ Method 1:

When parameter P402_d0=0, the system enables MPG control rapid traverse/feedrate override in method 1; the system set the current position (A point) to 0% of MPG override. From point A to 100 scale, every 1 scale in CW direction means an increase of 1% of MPG override; every 1 scale in CCW direction means an decrease of 1% of MPG override.

◆ Method 2:

When P402_d0=1, the system enters MPG controlling rapid/feedrate override according to method 2; when MPG override is set 0%, MPG override changes along MPG CW rotation, MPG CW rotation becomes gradually fast, MPG override is regulated 0%~ 100%. To avoid machine to be impacted by uneven speed of MPG, and the regulation range is less than 10% every time. MPG stops after it CW rotates, MPG override becomes 0%. After MPG CW rotates and rotates CCW(or CCW rotates and then stops), MPG override keeps the CCW instant override till MPG CW rotates (CW rotates and then stops). MPG controlling rapid/feedrate override explanation:

In AUTO working mode, before the machine program is not executed or the program pauses, single block stops, the cycle stops or the feed holds (including spindle/feed hold), 【MPG】indicator lights after pressing it means the system is in MPG controlling rapid/feedrate override. At right top, the yellow means MPG control mode and current MPG override. The system automatically cancels MPG controlling rapid/feedrate override mode after each program is executed.

【Note】

Page 85

Operation Chapter Four System Operation

In the thread machining commands (G32, G33, G34) , the feedrate is determined by the spindle

speed instead of F value, and MPG override is invalid here.

4.5.6 Interference operation in program execution process

4.5.6.1 Press key interference in program execution Interference operations in program execution:

EMERGENCY STOP: immediately stops not continuously start the execution. PAUSE: press CYCLE START to continuously execute the program. SINGLE BLOCK STOP: press CYCLE START to continuously execute after the block is

GSK96 Multi-function Position Control System User Manual

Note: see the specific symbol specification of

the external feed/spindle hold knob

displays CYCLE STOP: ON; and the system displays CYCLE STOP after M20 is executed.

4.5.6.2 External feed/ spindle hold knob The external feed/ spindle hold knob is valid in AUTO working mode. Whether the external feed/spindle hold knob is valid is controlled by P412_d6.

P412_d6=1: the system external feed/spindle hold knob is valid; the input signal is received by

MXZ1, MXZ2.

P412_d6=0: the system external feed/spindle hold knob is invalid; the pin of input signal can be

used as others.

◆ External feed/spindle hold knob introduction: The system has an external interface of feed/spindle hold knob. Move or stop the spindle and the

slider when the knob is placed on the different position. Use the knob to control conveniently the starting/stopping of spindle and the slide in debugging the program. There are three positions of feed hold knob and its function as follows:

Feed hold knob

Position 1: permit the spindle to rotate and the slider to traverse. Position 2: permit the spindle to rotate and forbid the slider to traverse. Position 3: forbid the spindle to rotate and the slider to traverse.

◆ External feed/spindle hold knob use: Before program running:

Press the corresponding key to control the spindle starting/stopping when the feed hold knob is placed to the position 1 and 2; but the spindle cannot be started when it is placed to the position 3. In SINGLE working mode:

When the External feed/Spindle hold knob is located at position 1, all the commands are executed as usual; when it is at position 2, the spindle control commands can be executed rather than the move commands of X, Z axes. These move commands can be executed only when the knob is rotated back to position 1. When it is at position 3, no block can be executed. To execute the blocks, rotate the knob back to position 2 or position 1. In CONTINUOUS run mode:

After the system starts programs, the feed hold knob can be rotated any time to control the spindle and the slider.

When the knob is placed to the position 1, programs run normally. When the knob is rotated from 1 to 2, the slider stops and the spindle still keeps the previous

Page 87

Operation Chapter Four System Operation

state. When the knob is rotated from 2 to 3, the spindle stops. When the knob is rotated from 3 to 2, the spindle recovers the previous state. When the knob is rotated from 2 to 1, the slider starts to run. The system will automatically exits from the auto initial state after ESC or RESET is pressed in

the course of the feed hold and the spindle stopping. The previous state of spindle and the unfinished commands cannot be reserved. Programs are restarted if the machining is executed continuously.

4.5.6.3 External start and pause signal External cycle start/pause signal is valid in AUTO working mode. Whether the external start/pause signal is valid is controlled by P412_d7.

P412_d7=1: the system external start/pause signal is valid; the input signal is received by ST, SP

pin.

P412_d7=0: the system external feed hold knob is invalid; the pin of input signal can be used as

others.

The external pause operation key signal (SP) has the same function with that of the feed hold key (cycle pause key) on the system panel; the external cycle start key signal (ST) has the same function with that of the cycle start key on the system panel. SP, ST are input to the system from the machine, and they are valid when the low level is connected.

Before the system is switched from other working mode to AUTO working mode, ―External start button‖ and ―External pause‖ button are released (power-off), otherwise, the system alarms.

The detailed circuit connection method is referred to CONNECTION, Chapter 3 CNC Device

Parameter operation characteristics including:

1) Press the parameter password level input by the operator to modify the corresponding level parameter.

2) When the operator directly presses ENTER instead inputting the password, the operation level is 4 to enter the parameter window in which the operator only reads but cannot modify the parameter.

3) For the parameter input and display format, the decimal must has the decimal point, and the negative number must has the negative sign; the system limits the valid digits to get the convenient operation and using safety.

4) The operator can open the prompt message window of parameter data input range.

5) The system automatically checks the parameter data after power-on and automatically prompts the initialization when it finds out the data in disorder.

6) The system sets the applicable safety parameters and the operator can reduce the accidences caused by the mistaken operation by the proper parameter setting.

4.6.1.1 Parameter privilege The parameter privilege is to modify the parameter password level. To get the convenient

management, the system provides the parameter privilege setting function, the current operation level is displayed on the top prompt bar in the parameter window.

Parameter password level settings from high to low are as follows: 1 level: *** set by the machine manufacturer, can modify the parameter range: parameter

level >=1; 2 level: *** set by the device administrator, can modify the parameter range: parameter level >=2 3 level: *** set by the machine operator, can modify the parameter range: parameter level >= 3;

Page 93

password);

③ Press ENTER after the input is completed, i.e. the system enters the operation level

corresponding password.

4.6.1.3 Parameter management

The parameter management includes the parameter display, the parameter privilege, initializing, solidifying, draw, sending and receiving the parameter according to the privilege. 【Parameter display】

Parameter color definitions:

The parameter permitted to modify by the system is displayed in yellow and the forbidden is displayed in white in the current privilege.

In the parameter window, some operation option is related to the privilege; press hp1 and the forbidden functions are displayed in grey.

Prompt message display:

The parameter value range prompt can be opened or closed when the operator input the

parameter.

Other display:

When the input exceeds the modification parameter, the system prompts No modification

authority in the parameter setting area.

In the parameter window, when the successfully modified parameter has a mark ―*‖ before its

parameter number, the system prompts the modification is completed successfully.

After the system executes some operations, the system displays the operation results and the successfully modified parameter has a mark ―*‖ before its parameter number，prompting the modification having been completed successfully. 【Parameter privilege】

For the different privilege, the parameter which can be modified is displayed in yellow, the forbidden is displayed in white. The parameter update (using USB to transmit the parameters) is to modify the parameter data in the current privilege. Privilege modification

The icon ahead of the parameter indicates the parameter is alterable under the current

password level privilege; indicates the parameter is unalterable.

Page 94

GSK96 Multi-function Position Control System User Manual

Privilege modification

The privilege modification is controlled by the password, and the password input is executed when the system enters the parameter password input window. Whether the password can be memorized is controlled by P416_d7. P416_d7=0: it is not memorized, and the system enters the parameter window in other working modes and the parameter password input window is displayed as follows:

1) Modify P416_d7=0;

【Parameter save】 The successfully modified parameters are automatically saved to the system, and all parameters are

saved when the system exits from the parameter window (entering the window in the other working mode by press key). When the system is turned on every time, it reads the saved parameter data. When the saved data in read exceeds the range, it is rewritten to the minimum in the range and the system prompts it. The read parameter in disorder in power-on, the system prompts whether the previous solidified parameter is read; when the parameters have not been solidified, the system prompts to select the stepper/servo parameter to execute the parameter initialization and to save them to the system. The main differences between the stepper and servo parameter are the different motion parameter values.

4.6.2 Parameter modification

The system parameter has been initialized before the factory delivery. The operator can modify

and regulate correspondingly the parameters according to the actual conditions of the machine.

The system displays the selected parameter number in highlight after the parameter is selected.

4.6.2.1 Parameter search The parameter search is to search the required parameter as follows:

Method 1:

4.6.3.1 Parameter communication and standard format According to the requirement to select the parameter transmission direction, the communication

has two kinds: parameter sending and receiving. The parameter receiving includes: USB→CNC,; the parameter sending includes: CNC→USB Parameter sending: (operation level: all level)

The operator in all level can send the parameter to U disc.

Parameter receiving: (operation level: machine manufacturer, device administrator, machine operator).

The operator with more than 3-level can receive the parameters from U disc However, it is only

valid for those parameters which can be modified in the corresponding level.

1. USB operation：USB→CNC, CNC→USB Press hp2 first, then press U to transmit the data by USB communication mode. The operator

selects the transmission direction according to the requirements.

When the parameter transmission is executed by U disc, the U disc root catalog needs to create

one file ―C001PAR‖ , the parameter sending and receiving are executed in the file. The file name format: ―PAR‖+file number(3-bit) +―.TXT‖

2. Standard format of TXT parameter file in U disc：(Refere to the format of the parameter file that the

system outputs to U disc).

In the U disc, the operator can use TXT, LST text to edit the parameter file, but the file name and

file content must be compiled according to the required standard format to correctly send to the system. Refer to the parameter file format of the system outputting as follows:

1) In PC, the operator should rename the parameter file name to TXT or LST suffix, such as

―PAR099.TXT‖; it is suggested the operator should use the TXT suffix to conveniently operate the parameter file on PC.

2) The home of TXT file content must be the parameter mark: ―CNC_GSKC001‖; the item must

exist.

3) The second line is the annotation, the front must have ―//‖; the item must exist.

4) The third line is the parameter content. The parameter content must meet its standard format

requirement.

Example: P000：00000.000 // Z program reference point

P000: it is the parameter number, its format is ―P + number + ：‖ which is the parameter number. The three parts are indivisible to consist of the parameter, the parameter number is

not correct when it lacks one. 00000.000 is the parameter content, ―//‖ is the parameter annotation.

5) The file content can be some of all parameters.

4.6.3.2 Parameter draw and solidifying The parameter seen in the window are saved to the system SRAM storage which has the

power-down protection function; when the main board battery has problem, the parameter loses.

The system has the parameter initialization function; according to the differences of the matched

motor drive unit, the system can execute the different initialization operation; the system matched with DA98 series drive unit should execute the servo initialization, the system matched with DY3 series drive unit should execute the stepper initialization. The main differences of the initial parameter of the servo and the stepper are X-motion parameter and others are the same. The differences of servo/stepper initialization value are referred to the motion parameter list in the appendix.

The initial parameter does not meet all machine and the machine manufacturer should modify

the spindle, the tool post and other parameters according to the detailed configuration of the machine.

To avoid the parameter loss, the system should execute the solidifying command, i.e. the

modified parameter is solidified to the system FLASH storage to backup, the FLASH storage without the battery has the permanent save function. When the current parameter loses, the system extracts the solidified parameter to recover it. The system pops-up the dialog box of relative operations about the parameter draw, solidifying, and the operator executes the option operation according to the corresponding dialog box. The parameter draw command includes: stepper parameter initialization, servo parameter initialization and machine manufacturer parameter draw. 【Explanation】

1) Before executing the parameter solidifying operation, the system should check the

corresponding parameter, and the system prompts the alarm message to require the operator to modify the corresponding parameter when the system find the parameter problem exists; after the parameter passes the check, it is saved to the system FLSAH to solidify.

2) The parameter solidifying operation must be executed before the solidified parameter draw.

4.6.3.3 System software upgrade and memory update The system software upgrade is to replace the new system software, i.e. the old software version

is replaced by the new; the main aim is to perfect the system function.

The system update is to update and improve the system software, so as to make the system

more stable. It does no harm to the system, but incorrect operation may result in the system update failure. If the update fails, the system cannot be started up, or even the system hardware will be damaged. Therefore, we suggest the user not upgrade the system software without authorization. It is recommended that the upgrade service be provided by our professional staff with our after-sale service center.

The system memory whole update is to replace the memory including the system software

covering memory.

The result of the memory whole update failure is more serious. It is suggested that the

operator cannot use personally and that our personnel provides the service.

The system upgrade and memory whole update mode: USB mode; which is performed only by the

machine tool builder.

1) System software upgrade by USB: After U disc is inserted, the system automatically performs the software upgrade according to the system prompt to execute the operation. When the system software uses USB mode to upgrade, U disc root needs creates one file ―C001DATA‖, the command sending and receiving must be in the file. The file name format: ―DATA‖+ file number (3-digit) +―.TXT‖. file name range: 0~254.

When the memory whole update uses USB, U disc root catalog needs to create the file

―C001MEMO‖, the command sending and receiving are executed in the file. The file name format: ―MEMO‖+file number(3-digit) +―.TXT‖. File number range: 0~254.

【Note】

1) When the system uses USB software upgrade, the operator presses ESC or RESET to return EDIT working mode to edit the current program once again after the upgrade is completed successfully, otherwise, the system alarms.

4.6.3.4 Functional command privilege

4.6.4 Parameter explanation

The parameters are described according to the functions and uses and their detailed definitions are the followings.

4.6.4.1 Reference point, software limit bit parameter __ P000～P020 The reference point parameters include all important coordinate positions of machine Z/X/Y, and the

each axis motion is based on these positions. 【Z/X/Y program reference point】__reference coordinate parameter P000, P001, P002 This parameter is used to set the position of program reference point. In AUTO/MANUAL mode, the machine returns to this position after program reference point return. The program reference point can be modified by inputting command (in MANUAL mode) or executing G50 command (in AUTO mode). The coordinate value of program reference point is the coordinates of the machine is not influenced by the tool offset value.

【2nd, 3rd program reference point of Z/X/Y】__reference coordinate parameter P003, P004, P005, P006, P007, P008

The 2nd and 3rd program reference point is similar to program reference point; In AUTO mode, after a specified axis performs G30, it returns to 2nd or 3rd program reference point commanded by G30. For details, please see to 4.10 G30 — 2nd, 3rd Program Reference Point Return in PROGRAMMING.

【Positive/negative tool nose software limit of Z/X/Y】__reference coordinate parameter P009, P010, P011, P012, P013, P014

The parameter is used to limit the motion range of tool nose coordinates. It confirms the max. positive/negative travel of tool post in Z, X, Y. In JOG /AUTO working mode, the tool nose coordinates of Z, X, Y are more than or equal to the positive tool nose software limit value, the axes only executes the negative instead of the positive motion. Otherwise, the system alarms: positive tool nose software limit alarm. The negative motion is also so. 【Positive/negative machine software limit of Z/X/Y】__reference coordinate parameter P015,

P016, P017, P018, P019, P020 The parameter is used to limiting the motion range of machine coordinates. It confirms the max.

In JOG /AUTO working mode, the machine coordinates of Z, X, Y are more than or equal to the positive mechanical software limit value, the axes only executes the negative instead of the positive motion. Otherwise, the system alarms: positive mechanical software limit alarm. The negative motion is also so.

4.6.4.2 Parameters related to zero return function __ P021～P026, P109～P111, P406～P407 【Machine zero coordinates of Z/X/Y】__reference coordinate parameter P021, P022, P023

The parameter confirms the coordinates of machine zero position. When the machine installs the machine zero check device and P407_d1=0, after the operator executes the ―Machine zero return (or G28) in JOG /AUTO working mode and the system has detected the ―zero signal‖, the system changes the current machine coordinate to the setting value of P021/P022P023. 【Zero offset value of Z/X/Y】__ reference coordinate parameter P024, P025, P026

When the system uses the servo motor, checking the deceleration signal and the zero turn signal of the motor mask are taken the zero return check; The deceleration signal installed on the coordinate axis coincides with the zero turn signal, which can influence the zero return precision; the operator should set the offset value to 2mm and avoid the 2mm to execute the check. 【Zero return low-speed of Z/X/Y】__ motion parameter P109, P110, P111

Zero-point low-speed return speed is the movement speed of coordinate axis when the zero-point signal detection being performed in the process of machine zero return. No matter this speed is higher or lower than the initial speed, the lower one should be used; Do not modified this speed after it is set; otherwise, the precision may be affected.
