1.2 The Concept of the Sequence Programming

The programming is performed a logic control to the machine tool and its relative equipments, which is called sequence programming.

After the programming is converted into some kind of format, CPU can be performed the code and calculation treatment for it, and its fruits can be memorized to RAM. CPU can be rapidly read each code stored in the memory, which can be performed the programming according to the calculation operation.

The compiling of the sequence programming starts with developing of the ladder diagram

Page 19

Installation and Connection Manual of GSK218MC CNC System

1.3 Distribution Interface (Step one)

The interface can be distributed after confirming the controlled object and calculating the points of the

Volume I Programming

corresponding input/output signal.

Refer to the Chapter Four Input/output interface signal table in the part of the Installation and Connection when distributing the interface.

VolumI Programming

1.4 Ladder Diagram Programming (Step two)

The control operation required by the machine tool can be expressed by the ladder diagram with the on-line compiling of the GSK218MC. The functions, such as the timer and counter, can not be expressed by relay symbols, which can be indicated by the specified function code symbols.

The compiled ladder diagram should be stored and converted into the corresponding PLC codes before operating, namely, the so-called instruction list.

1.5 Sequence Programming Debugging (Step 3)

The sequence programming can be debugged using the following methods:

1) Debugging with emulator The machine tool can be replaced by an emulator (it composes of the lights and switches). The input signal state of the machine tool can be expressed by the ON or OFF of the switches; and the output signal state can be indicated by the ON or OFF of the light.

2) Debugging with actual operation Debug on the actual machine tool. It is better to prepare the precautions before debugging, due to an unexpected behavior may occur.

Chapter Two Sequence Programming

CHAPTER TWO SEQUENCE PROGRAMMING

The operating principle is different with the common relay, because the PLC sequence controlling is carried out by compiling the on-line diagram. And therefore, it is better to thoroughly understand the sequence controlling principle when designing the PLC sequence programming.

2.1 Performance Process of Sequence Programming

In the general relay controlling circuits, each of them can be simultaneously operated. When the relay A is operated in the following figure, the replay D and E can be operated (when the contactor A and B are closed) at the same. Each replay in the PLC sequence control is operated in turn. The relay D is operated before relay A, and then the relay E operates (refer to the following figure). Namely, each relay is operated based upon the sequence of the ladder diagram (compiling sequence).

Fig. 2.1 (a) Circuit illustration

Volume I Programming

The differences between the relay circuit and PLC programming operation are shown below in the Fig.

2.1 (b) and Fig. 2.1 (c).

Fig. 2.1 (b)

Fig. 2.1 (c)

(1) Relay circuit Both Fig. 2.1 (b) and Fig. 2.1 (c) are shared a same operation. B and C are switched on after A is turned on. B is cut off after C is ON.

2.2 The Performance of the Cycle

VolumI Programming

PLC performs from the beginning to the end of the ladder diagram. It performs again from the beginning of the ladder diagram after this diagram is performed, which is called cycle performance.

The performance time from the beginning to the end of the ladder diagram is abbreviated as a period of a cycle treatment. The shorter of the treatment period is, the stronger of the response capacity of the signal is.

2.3 The Priority Sequence of the Performance (the 1st Level, the 2nd

level)

GSK218MC PLC program are composed of two parts: the 1st level program and the 2nd level program, which are inconsistent with the performance period.

The 1

level program performs once each 8ms, which can be treated some fast corresponding and

short pulse.

The 2

may divide the 2

program performs once each 8*nms. N is the partition value of the 2nd level program. PLC

level program into N parts when the 2nd level program is executed. It is performed

one part for each 8ms.

Fig. 2-3-1

PLC in the GSK218MC is separately performed in the PLC-AVR SCM. The 1ms of each 8ms is the communication time for reading the PLC data from the CNC. The 5ms is that the PLC gains the system control signal (F. X), and uploads the control result data (G, Y parameter) external port I/O. PLC is always performed the ladder diagram calculation other than the interruption of the response exchange data.

When the last partition value of the 2 executed from the beginning of the program. In this case, when the partition value is n, the performance time of one cycle is 8*n ms. The 1

program performs once each 8*n ms. If its steps of the 1

the steps of the 2

level program within 8ms should be reduced correspondingly; the partition value

may be increased, and the treatment time of the overall program will be longer. So, the compiling of

level program should be shorter.

2.4 Sequence Programming Structure

The ladder diagram is compiled with sequence in the traditional PLC. It owns the following advantages in the ladder diagram language allowing the structured programming:

1. The program is easy to comprehend and compile.

2. It is more convenient to find the faults during the programming.

3. It is easy to find some reasons when the operation malfunction occurs.

The methods of the main structure programming are shown below:

1) Sub-program The subprogram is regarded as a treatment unit based on the ladder diagram.

(3) The 2

The 2nd level program input signal register is also called the 2nd level program synchronic input signal register. Wherein, the stored input signal is treated by the 2nd level program. This signal state in the register is synchronic with the 2

The signals both in the NC and machine tool input register can be locked to the 2 input latch, as long as the 2nd level program performs. The signal state in this latch keeps invariable during the performance of the 2

2.5.2 The Treatment of the Output Signal

(1) NC output register The output signal transfers to the NC output register from the PLC each 8ms. (2) Machine tool output register The signal memorized in the machine tool output register conveys to the machine tool each 8ms.

Note: The signal states, such as the NC input register, NC output register, machine input register and machine output

register, which can be displayed by the self-diagnosis function. The diagnosis number is the address number in the sequence programming.

2.5.3 The Distinguish of the Signal State Between the 1st Level and the

2nd Level Program

As for the same input signal, their states may different between the 1st and 2nd level programming, that is the reason that different registers are used between two levels programming. Namely, the input

signal used with the 2 signal in the 2nd level program is later than the 1st level one. At the worst case, one 2nd level program performance cycle can be lagged. It is better to remember this point when programming the ladder diagram.

A=1 performs the 1st level program when the 1st 8ms is performed, then B=1. And therefore, the 2nd

level program is performed, the A=1 is latched to the 2

level program, and then the first partition of

the 2nd level program is completed.

latched as the one last time. So, C=1.

VolumI Programming

In this way, the state both B and C are different.

2.6 Interlocking

In the sequence control, the interlocking is very important from the safety issue.

It is necessary to use the interlocking in the sequence control programming. Simultaneously, the hard interlocking is used in the relay control circuit of the strong electric cabinet of the machine tool sides. This is the reason that the interlocking is disabled when the hardware of the performance sequence programming malfunctions, even if the interlocking is logically used in the sequence program (software). And therefore, the interlocking can be ensured the safety for the user, and prevent the machine tool from damaging in the strong electric cabinet of the machine sides.

The design of the sequence program begins from the compiling of the ladder diagram. The ladder diagram consists of relay contact and function code. The logic relationship in the ladder diagram composes of sequence program. There are two methods of the sequence program input: one is that the input method uses the mnemonic symbol language (The system is not temporarily supported the

CHAPTER EIGHT SPINDLE SPEED FUNCTION

8.1 Spindle Speed Control Method

Brief: GSK218MC divides the spindle into gear spindle and analog spindle based upon the control

method.

1. In the gear spindle, the CNC controls the spindle speed by which the S code turns into switch value and then outputs to the spindle.

2. In the analog spindle, the CNC controls the spindle speed by which the S code turns into analog value and then outputs to the spindle.

The I/O point or analog value control can be set by bit 2 of bit parameter No.1.

Volum e Ⅱ Function

8.1.1 Gear Spindle

Brief: The gear spindle means that the spindle S code is controlled by I/O.

Signal Spindle speed strobe signal TF（F007＃2）

Gear spindle address signal F22#0～F22#7

[Type] Output signal [Function] These signals have been indicated that the specified spindle speed function has been performed actually. [Output condition] Refer to the “S code miscellaneous function in Section for spindle S code I/O point control” for the output condition and performance process.

Note: S code range: S1～S8, the alarm may occur if it exceeds its range, S1～S8 are separately corresponding with

the F address signal F022#0~#7. User can refer to three gears (S1, S2 and S3) of the configurated ladder diagram from the system. So, S4~S8 can not be used, the corresponding ladder diagram should be added if the user needs.

8.1.2 Analog Spindle

Brief: Analog spindle is that the spindle speed is controlled by the analog voltage value of the CNC.

CNC can be controlled the spindle speed of which the S code turns into the analog voltage value outputting to the machine’s spindle.

Actual output analog voltage value = spindle controlled S value x spindle override.

Signal GSK218MC integration CNC system: Spindle override SOV1 (X31.0) Spindle override SOV2 (X31.1) Spindle override SOV4 (X31.2)

[Type] Input signal [Function] This signal specifies that the spindle controls the override change of the S value.

Chapter Eight Spindle Speed Function

GSK 218MC-H and GSK 218MC-V CNC system: Spindle override code detection signal (G019#0~G019#2)

[Input] Input signal [Function] It is the spindle override code detection signal Spindle override code detection signal has 3 binary system code signals which are corresponding with the override: So, the spindle override can be selected based upon the 10% unit within the 50~120%.

When the spindle speed control is performed instead of using the spindle speed override, the setting override value is 100%.

Notice: The spindle speed override function in the tapping cycle and thread cutting is disabled.

Gear shift treatment

Although the S code is spindle speed, its actual controlled member is spindle motor, and therefore, the CNC should be affirmed the corresponding relations between spindle motor speed and gear. The CNC selects the gear shift based upon the defined speed range of each gear shift in advance, as it is directly selected by S code. The PLC can be selected the corresponding gear shift using its selection signal (GR3, GR2 and GR1). Simultaneously, the CNC outputs the spindle motor speed based upon

the selected gear shift. Specify the S0

spindle speed in the MDI operation. Two or three speed gear shifts (GR1, GR2 and GR3) can be set

by parameter No.246

～248, and then the gear shift selection signal can be output at the same time.

When the gear shift selection signal changes, the SF signal is simultaneously output.

The meaning of the gear shift signal is shown below:

8.2 Rigid Tapping

Brief: The rigid tapping is synchronized the tapping axis and spindle axis in the common tapping

canned cycle.

The CNC needs to detect the rotation direction signal of the spindle ensuring the direction and processing of the cutting feed during the rigid tapping (during performing G74 and G84).

Performance processing: Spindle rotates → Z axis feed tapping → sending the M05 stop code to spindle → after the spindle is absolutely stopped → sending a reverse code → Z axis retracts to the start → spindle stops

The corresponding ladder diagram should be compiled for carrying out the rigid tapping; inform the rotation direction of the CNC external spindle.

9.2 Canned Cycle

Brief: Canned cycles can be simplified the program. With a canned cycle, a frequently-used

machining operation can be specified in a single block with a G function; without canned cycles, normally more than one block is required. In addition, the use of canned cycles can shorten the program to save memory. Explanations: A canned cycle consists of a sequence of 6 operations:

Operation 1 Positioning a hole position Operation 2 Rapid traverse up to Point R level Operation 3 Hole machining Operation 4 Operation at the bottom of a hole Operation 5 Retraction to point R level Operation 6 Rapid traverse up to the initial point
