SAFETY PRECAUTIONS

4291-E P-(i)

SAFETY PRECAUTIONS

The machine is equipped with safety devices which serve to protect personnel and the machine
itself from hazards arising from unforeseen accidents. However, operators must not rely exclusively
on these safety devices: they must also become fully familiar with the safety guidelines presented
below to ensure accident-free operation.
This instruction manual and the warning signs attached to the machine cover only those hazards
which Okuma can predict. Be aware that they do not cover all possible hazards.

1. Precautions Relating to Machine Installation

(1) Install the machine at a site where the following conditions (the conditions for achievement of

the guaranteed accuracy) apply.

• Ambient temperature:17 to 25°C

• Ambient humidity:40% to 75% at 20°C (no condensation)

• Site not subject to direct sunlight or excessive vibration; environment as free of dust, acid,

corrosive gases, and salt spray as possible.

(2) Prepare a primary power supply that complies with the following requirements.

• Voltage: 200 V

• Voltage fluctuation: ±10% max.

• Power supply frequency: 50/60 Hz

• Do not draw the primary power supply from a distribution panel that also supplies a major

noise source (for example, an electric welder or electric discharge machine) since this could
cause malfunction of the CNC unit.

Eeoemm6pl001

Eeoemm6pl002

• If possible, connect the machine to a ground not used by any other equipment. If there is no
choice but to use a common ground, the other equipment must not generate a large amount
of noise (such as an electric welder or electric discharge machine).

(3) Installation Environment

Observe the following points when installing the control enclosure.

• Make sure that the CNC unit will not be subject to direct sunlight.

• Make sure that the control enclosure will not be splashed with chips, water, or oil.

• Make sure that the control enclosure and operation panel are not subject to excessive vibra-

tions or shock.

• The permissible ambient temperature range for the control enclosure is 0 to 40°C.

• The permissible ambient humidity range for the control enclosure is 30 to 95% (no conden-

sation).

• The maximum altitude at which the control enclosure can be used is 1000 m (3281ft.).

2. Points to Check before Turning on the Power

(1) Close all the doors of the control enclosure and operation panel to prevent the entry of water,

chips, and dust.

(2) Make absolutely sure that there is nobody near the moving parts of the machine, and that there

are no obstacles around the machine, before starting machine operation.

Eeoemm6pl003

(3) When turning on the power, turn on the main power disconnect switch first, then the CONTROL

ON switch on the operation panel.

3. Precautions Relating to Operation

4291-E P-(ii)

SAFETY PRECAUTIONS

(1) After turning on the power, carry out inspection and adjustment in accordance with the daily

inspection procedure described in this instruction manual.

(2) Use tools whose dimensions and type are appropriate for the work undertaken and the machine

specifications. Do not use badly worn tools since they can cause accidents.

(3) Do not, for any reason, touch the spindle or tool while spindle indexing is in progress since the

spindle could rotate: this is dangerous.
(4) Check that the workpiece and tool are properly secured.
(5) Never touch a workpiece or tool while it is rotating: this is extremely dangerous.
(6) Do not remove chips by hand while machining is in progress since this is dangerous. Always

stop the machine first, then remove the chips with a brush or broom.
(7) Do not operate the machine with any of the safety devices removed. Do not operate the

machine with any of the covers removed unless it is necessary to do so.
(8) Always stop the machine before mounting or removing a tool.
(9) Do not approach or touch any moving part of the machine while it is operating.
(10) Do not touch any switch or button with wet hands. This is extremely dangerous.
(11) Before using any switch or button on the operation panel, check that it is the one intended.

4. Precautions Relating to the ATC

(1) The tool clamps of the magazine, spindle, etc., are designed for reliability, but it is possible that

a tool could be released and fall in the event of an unforeseen accident, exposing you to danger:

do not touch or approach the ATC mechanism during ATC operation.
(2) Always inspect and change tools in the magazine in the manual magazine interrupt mode.

Eeoemm6pl004

Eeoemm6pl005

(3) Remove chips adhering to the magazine at appropriate intervals since they can cause misoper-

ation. Do not use compressed air to remove these chips since it will only push the chips further

in.
(4) If the ATC stops during operation for some reason and it has to be inspected without turning the

power off, do not touch the ATC since it may start moving suddenly.

5. On Finishing Work

(1) On finishing work, clean the vicinity of the machine.
(2) Return the ATC, APC and other equipment to the predetermined retraction position.
(3) Always turn off the power to the machine before leaving it.
(4) To turn off the power, turn off the CONTROL ON switch on the operation panel first, then the

main power disconnect switch.

SAFETY PRECAUTIONS

6. Precautions during Maintenance Inspection and When Trouble Occurs

In order to prevent unforeseen accidents, damage to the machine, etc., it is essential to observe the
following points when performing maintenance inspections or during checking when trouble has
occurred.

(1) When trouble occurs, press the emergency stop button on the operation panel to stop the

machine.

(2) Consult the person responsible for maintenance to determine what corrective measures need to

be taken.

(3) If two or more persons must work together, establish signals so that they can communicate to

confirm safety before proceeding to each new step.
(4) Use only the specified replacement parts and fuses.
(5) Always turn the power off before starting inspection or changing parts.
(6) When parts are removed during inspection or repair work, always replace them as they were

and secure them properly with their screws, etc.
(7) When carrying out inspections in which measuring instruments are used - for example voltage

checks - make sure the instrument is properly calibrated.
(8) Do not keep combustible materials or metals inside the control enclosure or terminal box.
(9) Check that cables and wires are free of damage: damaged cables and wires will cause current

leakage and electric shocks.
(10) Maintenance inside the Control Enclosure

a) Switch the main power disconnect switch OFF before opening the control enclosure door.

Eeoemm6pl007

b) Even when the main power disconnect switch is OFF, there may some residual charge in the

MCS drive unit (servo/spindle), and for this reason only service personnel are permitted to
perform any work on this unit. Even then, they must observe the following precautions.

• MCS drive unit (servo/spindle)
The residual voltage discharges two minutes after the main switch is turned OFF.

c) The control enclosure contains the NC unit, and the NC unit has a printed circuit board

whose memory stores the machining programs, parameters, etc. In order to ensure that the
contents of this memory will be retained even when the power is switched off, the memory is
supplied with power by a battery. Depending on how the printed circuit boards are handled,
the contents of the memory may be destroyed and for this reason only service personnel
should handle these boards.

(11) Periodic Inspection of the Control Enclosure

a) Cleaning the cooling unit

The cooling unit in the door of the control enclosure serves to prevent excessive temperature
rise inside the control enclosure and increase the reliability of the NC unit. Inspect the follow­ing points every three months.

• Is the fan motor inside the cooling unit working?
The motor is normal if there is a strong draft from the unit.

• Is the external air inlet blocked?
If it is blocked, clean it with compressed air.

7. General Precautions

4291-E P-(iv)

SAFETY PRECAUTIONS

(2) Wear appropriate clothing while working, and follow the instructions of someone with sufficient

training.

(3) Make sure that your clothes and hair cannot become entangled in the machine. Machine opera-

tors must wear safety equipment such as safety shoes and goggles.

(4) Machine operators must read the instruction manual carefully and make sure of the correct pro-

cedure before operating the machine.

(5) Memorize the position of the emergency stop button so that you can press it immediately at any

time and from any position.

(6) Do not access the inside of the control panel, transformer, motor, etc., since they contain high-

voltage terminals and other components which are extremely dangerous.

A multi-main CPU system on which up to seven engines (main CPUs) can be mounted is used.
An excellent performance and cost effectiveness have been realized as a leader of increasingly
rapid and accurate machine tools. The CNC system can be adapted to any models and varia­tions by changing the construction of the main CPUs. The machine is controlled by a built-in
PLC.

(2) Compact and highly reliable

The CNC system has become compact and highly reliable because of advanced hardware
technology, including UCMB (Universal Compact Main Board), I/O link, and servo link. The
'variable software' as a technical philosophy of the OSPs supported by a flash memory. Func­tions may be added to the CNC system as required after delivery.

(3) NC operation panels

The following types of NC operation panels are offered to improve the user-friendliness.

• Color CRT operation panels

• Thin color operation panels (horizontal)

• Thin color operation panels (vertical)

One or more of the above types may not be used for some models.

(4) Machining management functions

These functions contribute to the efficient operation of the CNC system and improve the profit­ability from small quantity production of multiple items and variable quantity production of varia­tions. Major control functions are described below.

Eeoemm6an001

a) Reduction of setup time

With increase in small-volume production, machining data setting is more frequently
needed. The simplified file operation facilitates such troublesome operation. The documents
necessary for setup, such as work instructions, are displayed on the CNC system to elimi­nate the necessity of controlling drawings and further reduce the setup time.

b) Production Status Monitor

The progress and operation status can be checked on a real-time basis on the screen of the
CNC system.

c) Reduction of troubleshooting time

Correct information is quickly available for troubleshooting.

1-1-2. General Points Relating to Animation

4291-E P-5

SECTION 1 REAL 3D ANIMATED SIMULATION

(1) Animation speed

There is a limit on the feedrate that can be displayed by the animation function.
If the feedrate exceeds this limit during animation, the message “ANIM SPEED OVER” is dis­played, and removal of stock and the tool path are not shown.
To clear the “ANIM SPEED OVER” error, perform one of the following:

• Select ERASE.

• Reset the NC.

• Change the range or angle.

1-1-3. High-speed Drawing

Programmed tool paths can be drawn at a high speed when the machine lock mode is set. ON/OFF
setting for the single block function is valid during high-speed drawing.

1-1-4. Cutting Time Display

The execution time of a program differs depending on whether or not the machine lock function is
set.

(1) Machine lock function ON

Length of timer required for axis movements is calculated at the completion of each block and
added. In this calculation, the time spent for the execution of S, T, M commands and G04 is dis­regarded.
Cutting time is calculated based on the feedrates that are obtained by “programmed F value x
override value (the value valid at the start of a block)”. For rapid feed operation, time is calcu­lated assuming override setting of 100%.

Eeoemm6f1004

Eeoemm6f1005

Eeoemm6f1006

(2) Machine lock function OFF

Total machine operating time is calculated.

SECTION 1 REAL 3D ANIMATED SIMULATION

1-1-5. Selection of Material Shape and Tool Shape

4291-E P-6

The material shape and tool shape used for the 3D animated simulation function are included in all
programs created using the IGF function, so they are automatically set when a program created
using the IGF function is called.

[Supplement]

When the tool shape has to be changed, refer to ANIMATED SIMULATION (2D), Tool Shape Defi­nition.

1-1-6. System Variables

The following system variables can be referred to and updated from an NC program.

Application of System Variable System Variable Name Possible Settings

1-1-7. Return Search

It is possible to designate if tool path during return search is drawn in 3D animation by selecting [F2]
(RESTART) or by the procedure for selecting return search from the MAIN PRG_OPER.

[Supplement]

If return search tool path is drawn, it will take a longer time than the time required for return search
without 3D animation drawing.

1-1-8. Processing at the Selection of NC Program

It is possible to set whether or not “automatic scaling” and “material drawing” are automatically exe­cuted after reading the NC program. This setting is made when selecting NC program.

1-1-9. Other Considerations

(1) On switching between 2D and 3D animation during execution of a main program, the screen is

temporarily cleared, then drawing starts again. Drawing starts from the point where the switcho­ver was made, with no trace of the cutting up to that point remaining.

(2) When the graphic display is displayed in a pop-up window by selecting the ANIMATE ON/OFF

function key on screens other than the ANIMATED SIMULATION screen, such as the ACTUAL
POSITION screen and program display screens, the type of display (2D or 3D) is determined by
the mode selected on the ANIMATED SIMULATION screen.

2-1. Features and Main Functions

4291-E P-7

The animated simulation (2D) function displays the tool paths and the portion being machined in
graduated painting patterns according to the machined depth, thus simulates the removal of stock
from the material.
The animated simulation (2D) function makes the following possible.

• Display of both split view and solid view.
In the display of split view, display in two planes (split display) is possible.
Switchover between these two modes of display is possible at any time.

4291-E P-34

SECTION 1 REAL 3D ANIMATED SIMULATION

When AUTO SCALE is selected, the material that is assigned the same spindle position and the
rotary axis set at the GRAPHIC DATA window is searched from the registered materials, the graphic
drawing area is automatically calculated and determined based on the material data.
If necessary, margin can be taken around the material. This area can be set by percent to the mate­rial drawing area at the GRAPHIC DATA window.
The auto scale function is valid only for the display given when automatic scaling is executed.
If the material assigned the same conditions is not registered, “No blank data” error occurs.

2-4-8. HIGH DRAW

The high-speed drawing executes animated simulation at high speed.
This function is valid when the machine lock function is ON in the automatic or MDI operation mode.
Each time [F7] (HIGH DRAW) is selected, high-speed drawing mode is turned on and off.
In the HIGH DRAW mode, animated drawing is executed for each block and path, envelope and
enveloped figure are drawn in this order. The position tool is not drawn.
The HIGH DRAW mode is cleared when the NC is reset or the program end command is executed.

[Supplement]

1) In the HIGH DRAW mode, G00 mode movement is executed in linear interpolation like G01.
Therefore, the drawn path differs from the actual tool path.

2) In the HIGH DRAW mode, drawing is given at the center of the screen.

3) The 3D arc (includes G02 and G03 in the 3D coordinate system) is expressed in a line that con­nects the start and end points of the arc if the NC is started in the HIGH DRAW mode or restart
search.

Eeoemm6f1039

<Explanation>

Registers the material shape.
Material definition consists of the start declaration, registration procedure statement (see the INDEX
and DIREC items), shape command string, and end declaration.

<Example>

To register cylindrical material, having the center at (250, 0), bottom radius of 226, bottom height of
0 and top face height of 81, to registration No. 1 under the conditions that the cutting direction is V
and there is no rotary axis specification. For the definition, coordinate system number 1 is used.

DEF WORK [1] ............................. Material definition start declaration

DIREC V ............................. Registration procedure statement

ORIGIN H1 ............................. Shape command string

CYLNDR 0P, [250, 0] 226, 0, 81 ............................. Shape command string

END ............................. Material definition end declaration

[Supplement]

1) When defining the material shape, the work coordinate system where NC program is written is
used with the unit system fixed at "mm" or "0.1 inch".

2) Up to 32 kinds of materials can be registered using CYLNDR and CYLNDRI.

3) Up to 32 sets of ORIGN can be registered.

2-5-2. CYLNDR and CYLNDRI

The coordinate system used for defining a material with CYLNDR and CYLNDRI is changed accord­ing to the spindle position.
HL (horizontal axis "left") and HR (horizontal axis "right"): X → Z, Y → X, Z → Y.
HF (horizontal axis "front") and HB (horizontal axis "back"): X → Y, Y → Z, Z → X.
For example, if the following is defined as the material:
Cylinder 0P [-250, 0], 226, 0, 81 Cylinder
[-250, 0]: Center, 226: Diameter, 0, 81: Bottom heights
Then, the axis that corresponds to the set value for the center and the height is determined as
shown in the table below according to the data of the registration procedure statement "DIREC".

SECTION 3 SYNCHRONIZED TAPPING / TORQUE MONITORING FUNCTIONS

1-1-2. Details of Commands

4291-E P-55

(1) G Codes Calling a Tapping Cycle (G84, G284)

Whether G84 calls a conventional float tapping cycle or a synchronized tapping cycle is deter­mined by the setting for NC OPTIONAL PARAMETER (SYNCHRONIZED TAPPING) “G84 /
G74 TAP MODE”. Even if the setting is made for synchronized tapping, it calls a float tapping
cycle if the synchronized tapping specification is not selected.

[Supplement]

This parameter is provided to allow a tapping cycle having been programmed using G84 / G74
to be used in the synchronized tapping mode without modifying the existing program. Accord­ingly, it is recommended to specify a tapping cycle in the conventional mode if you program it
using G84 / G74. Note that the setting for this parameter is disregarded if the synchronized
tapping specification is not selected and G84 / G74 tapping cycle commands are executed in
the conventional float tapping mode.

G284 is always executed in the synchronized tapping mode independent of the setting for NC
OPTIONAL PARAMETER (SYNCHRONIZED TAPPING) “G84 / G74 TAP MODE”.

(2) G Codes Calling a Reverse Tapping Cycle (G74, G274)

The tapping cycle mode called by G74 is determined according to the setting for NC OPTIONAL
PARAMETER (SYNCHRONIZED TAPPING) “G84 / G74 TAP MODE” as with G84.
G274 is always executed in the synchronized tapping mode independent of the setting for NC
OPTIONAL PARAMETER (SYNCHRONIZED TAPPING) “G84 / G74 TAP MODE” as with G284.

Float Tapping Synchronized Tapping

G84, G74 Usable Usable

G284, G274 Not usable Usable

Eeoemm6f3003

(3) Tapping Position (X, Y)

The X and Y coordinate values determine the tapping position.
If X and/or Y is omitted, the coordinate value(s) valid in the previous block are used.

(4) Bottom Level of Tapping Cycle (Z)

In the G90 mode, the command specifies the level in the selected coordinate system. In the
G91 mode, however, the bottom level must be specified by the distance from the point R level.
Designation of the bottom level may be omitted. If you omit the command, the bottom level is
determined according to the general rule for fixed cycles. (For the general rule for fixed cycles,
refer to the Programming Manual.)

(5) Point R Level (R)

The command specifies the level of point R.
Designation of the point R level may be omitted. If you omit the command, the point R level is
determined according to the general rule for fixed cycles.

(6) Spindle Start Position at Point R Level (E)

This specifies the cut-in start position at the start of a tapping cycle by the spindle angular posi­tion (absolute value). This command is valid only for a synchronized tapping cycle and disre­garded for a float tapping cycle (designation of this command for a float tapping cycle does not
cause an alarm).
Designation of the spindle position data may be omitted. If you omit the command, the spindle
position is determined according to the general rule for hole machining data.
The command is treated as a modal command in a fixed cycle mode. If the command is omitted
and none of the spindle start position command has been designated after the entry to a fixed
cycle mode, the cutting start position is not controlled and the cutting starts from the actual
spindle position.

4291-E P-56

SECTION 3 SYNCHRONIZED TAPPING / TORQUE MONITORING FUNCTIONS

(7) Dwell Period at the Bottom Level (P)

The command specifies the length of time the tool dwells at the bottom level. You may specify
the desired dwell period in the same manner as in the G04 mode operation.
Designation of the dwell period may be omitted. If you omit this command, the dwell period is
determined according to the general rule for a fixed cycle.

(8) Dwell Period at the Point R Level in Return Cycle (Q)

The command specifies the length of time the tool dwells at the point R level. The length of time
may be specified in the same manner as a P command explained in item (7) above.
Designation of the dwell period may be omitted. If you omit this command, the dwell period is
determined according to the general rule for a fixed cycle.

(9) Feedrate (F)

Specify axis feedrate to be applied to axis feed within the cutting feed areas in a cycle opera­tion.
Determine the value so that Z-axis feed distance per revolution of the spindle equals the tap
thread pitch.
Feedrate may be calculated from the thread pitch of the tap (P) and the spindle speed (S). In
the feed per minute mode (G94), F = P * S and in the feed per revolution mode (G95), F = P.
Designation of the dwell period may be omitted. If you omit this command, the dwell period is
determined according to the general rule for a fixed cycle.
Designation of an F1-digit feed command will cause an alarm.

(10) Spindle Speed (S)

The command specifies the spindle speed (synchronized feed speed of the spindle) during tap­ping.
Designation of a spindle speed may be omitted. If you omit this command, the spindle speed is
determined according to the general rule for a fixed cycle. The gears for driving the spindle are
automatically determined according to the specified S value. When the fixed cycle mode is can­celed, the gears for normal operation are selected depending on the S value.

[Supplement]

M40 to M43 are disregarded during a synchronized tapping fixed cycle operation.

(11) Spindle Gear Selection (M)

During a synchronized tapping operation, spindle drive gear range is automatically selected
meeting the spindle speed command value.
If the gear range selected automatically does not meet actual tapping operation, you can select
the desired gear range by specifying an M code.
M234:Selects the gear range meeting the specified spindle speed.
M235:Selects the second gear range for the spindle speed that is usually executed in the first
gear range.
M236:Selects the third gear range for the spindle speed that is usually executed in the first or
second gear range.
M237:Selects the fourth gear range for the spindle speed that is usually executed in the first,
second or third gear range.

[Supplement]

During synchronized tapping operation, gear range selection M codes (M40 to M43) are disre­garded. They become valid when the synchronized tapping mode is canceled.

1), 2) Positioning is executed at (X, Y) at a rapid feedrate.
At the same time, spindle drive gears are selected meeting the specified spindle speed
(S command), then the spindle stops.
If an M code is specified in the same block, gear range selection and spindle stop control
are executed after the completion of positioning and specified M code operations.

3), 4) Positioning is executed at the point R level at a rapid feed rate.
If the block includes an E command, spindle orientation is executed at point E in the
specified spindle rotating direction (in the direction of tapping).

5) With the spindle rotating in the CW direction, Z-axis feed is controlled in synchronization
with spindle rotation up to the point Z level.

6) At the point Z level, the Z-axis dwells for P seconds if a P command is designated.

7) With the spindle rotating in the CCW direction, Z-axis feed is controlled in synchroniza­tion with spindle rotation up to point R level.

8) At the point R level, the Z-axis dwells for Q seconds if a Q command is designated.

9) Positioning is executed at the return point level at a rapid feedrate.

In operation steps 5), 6) and 7), settings of feed override and spindle override are disregarded
and axis feed and spindle rotation are controlled assuming 100% for both of them.
In operation steps 5), 6) and 7), dry run operation is always disabled.

SECTION 3 SYNCHRONIZED TAPPING / TORQUE MONITORING FUNCTIONS

(2) Reverse Tapping Cycle Command (G74, G274)

In comparison to the tapping cycle explained in item (1) above, operations are same as those in
the tapping cycle with an exception the spindle rotating direction in operations 4), 5) and 6) is
reversed.

[Supplement]

1) Although the spindle remains rotating at the completion of a tapping cycle that uses a float-

ing tapper, the spindle stops at the end of a synchronized tapping cycle.

2) If the NC is reset during a synchronized tapping cycle, the gears selected for the execution

of the synchronized tapping cycle remain selected. The gear range is automatically
selected meeting the spindle speed with M40 to M43 taken into account when the spindle
is started next by a spindle start command (M03, M04), a spindle orientation command
(M19, M118, M119), an S command, or manual spindle operation.

(3) Slide Hold

If the [SLIDE HOLD] button is pressed during the execution of operation 5), the spindle stops
immediately, the spindle rotation is reversed to CCW and the Z-axis moves up to the point R
level in the synchronized operation. The spindle stops when the Z-axis reaches the point R
level.
If the [SLIDE HOLD] button is pressed during the execution of operation 5), the Z-axis deceler­ates. If the distance for the Z-axis to decelerate before it stops is larger than the remaining dis­tance to the point Z level, pressing of the [SLIDE HOLD] button is disregarded. The Z-axis
keeps moving to the point R level and it stops there.
If the [SLIDE HOLD] button is pressed during the execution of operation 6), 7), the Z-axis stops
after it has reached the R-point level.
If the start button is pressed in the above state (where the spindle stops at point R level), the
spindle and Z-axis perform synchronized feed again to the point Z level.

[Supplement]

The manual intervention key is invalid while the spindle stops at point R level in the SLIDE
HOLD mode.

1-3. Notes on Synchronized Tapping Operation

4291-E P-59

(1) G284 and G274 call the fixed cycle mode and G80 is used to cancel the fixed cycle mode.

Besides G80, G00, G01, G02 and G03 also cancel the fixed cycle mode.

(2) Specify an F command when designating G284 or G274 after turning on the power, resetting

the NC or canceling a fixed cycle. The fixed cycle mode is not canceled if other fixed cycle is
called.

(3) Specify an S command when designating G284 or G274 after turning on the power or resetting

the NC. An S command must be specified in a preceding or the same block that contains G284
or G274.

Eeoemm6f3005

<Example>

S320
:
:
G284

(4) The feed override and spindle override functions are disabled while spindle rotation and axis

feed are synchronized.

(5) Whether or not the cycle stops at point R level in the single block state is determined according

to the setting (DOES, DOES NOT) for “SINGLE BLOCK STOP AT POINT R LEVEL” of NC
OPTIONAL PARAMETER (FIXED CYCLE).

(6) Since the gear range for synchronized tapping is used during the synchronized tapping mode,

the gear range is changed at the entry to the synchronized tapping mode.

(7) Mid-block sequence restart operation does not allow you to restart the program from the opera-

tion synchronized between the spindle and the Z-axis feed. Internal processing for sequence
restart cannot be stopped until the point R level is reached.

(8) In the STM lock or machine lock state, Z-axis feed is executed at the specified feedrate. In this

state, Z-axis commands are executed assuming that the spindle is rotating.

NOTICE

1) To restart the sequence from a block specified in the synchronized tapping mode, specify
a block that does not contain synchronized axis feed operation. If sequence restart is
made from such a block, the gear range may not be selected appropriately disabling syn­chronized feed.

2) Do not change the ON/OFF state of the STM lock in the synchronized tapping mode. Oth­erwise, gear range may not be executed appropriately or the spindle control may be
incorrect.

[Supplement]

The NC is in the M326 state when it is reset.

2-2. Parameters

The TAPPING TORQUE MONITOR PARAMETER screen is used to set the threshold level for moni­toring the tapping torque. Setting is made in unit of “kgf·m”.
Five sets of parameters are provided and the parameter to be used for monitoring should be speci­fied by its number using system variable VTMNO.
The parameter presently selected is displayed in yellow.

can be used).

[Supplement]

1) From the standpoint of avoiding breakage of a tap, a smaller value will be effective. This, how­ever, lowers cutting performance.

2) The selected parameter number is held even when the power is turned off.

3) If a parameter number for which “0” is set is selected, tapping torque is not monitored

SECTION 3 SYNCHRONIZED TAPPING / TORQUE MONITORING FUNCTIONS

2-3. Setting the Immune Period

4291-E P-61

When starting the spindle from the state it is stopped, starting current flows the spindle motor that

Eeoemm6f3009

could cause the spindle torque to exceed the maximum allowable load. The overload state caused
by the motor start current is ignored in the two stages of processing indicated below.

• Overload state is ignored until the actual spindle speed reaches A% of the spindle speed spec­ified by an S command.

• After the actual spindle speed has reached A% of the specified speed, the function further stays
immune for “t” [100 msec] to allow the spindle to rotate in the stabilized state. Torque monitoring
starts after the end of these two stages.

2-4. Torque Monitoring Method

4291-E P-62

If spindle torque exceeds the set value continuously for approximately “10 * n” [msec] continuously,
an alarm occurs and the following alarm message is displayed: Alarm B 2447 Synchronous tap's
torque low.
At the occurrence of the alarm, the Z-axis returns back to the point R level at the synchronized feed
mode and stops there.
Torque is continuously monitored until deceleration starts.
Value “n” above is set for NC optional parameter (SYNCHRONIZED TAPPING).
TORQUE LOW FOR SYNCHRONIZED TAPPING, NUMBER OF TORQUE OVER TIME
n Recommended value: 4 [times]

[Supplement]

If “0” is set for “n”, torque monitoring is not executed.

2-5. Display

The state of torque monitoring can be displayed on the LOAD MONITOR window that appears by
selecting [F3] (LOAD ON/OFF) from the function menu in each operation mode. The window can
also be displayed on the MAIN PROGRAM and SCHEDULE PROGRAM screens.

Eeoemm6f3010

(a) The LOAD MONITOR meter displays the load in three colors: blue (load up to the continuous

rating of the spindle motor); yellow (over the continuous rating of the spindle motor and up to the
short-time rating); red (over the short-time rating of the spindle motor). The peak state will be
maintained. The LOAD MONITOR meter is reset each time the LOAD MONITOR window
appears.

(b) “TORQUE MONITOR” is displayed as torque monitoring begins, indicating that the torque is

being monitored. If the spindle load ratio exceeds the maximum load ratio of the torque, the
background color of the “TORQUE MONITOR” frame changes from green to yellow.

(c) The value displayed on the right side of “TORQUE MONITOR” is the tapping torque monitor

parameter number currently selected.

SECTION 3 SYNCHRONIZED TAPPING / TORQUE MONITORING FUNCTIONS

(d) The maximum load ratio of the torque (%) on the right side of the parameter number described

in c) above is calculated by converting the set value of the “tapping torque monitor parameter”
based on the spindles continuous rating. The continuous rating of the spindle must therefore be
set with the parameter. For the set value, see the final specifications.

• For the parameter, set the continuous rating after converting it into “W”.

[Supplement]

1) If no value is set for the parameter, torque is not monitored.

2) Spindle overload monitoring is not executed while synchronized tapping torque is moni-

tored. Note spindle overload monitoring using a meter relay is executed. Attachment load
monitoring is executed normally.

TION (MID-BLOCK RESTART FUNCTION)

Eeoemm6f4001

NOTICE

This specification is closely related to the standard sequence restart function.
Before reading this chapter, you are required to thoroughly understand the “return search and
sequence restart” operation described in the Operation Manual.

If automatic operation is interrupted during the execution of a block, the standard sequence restart
function allows the cutting tool to return to the end point of the block immediately preceding the inter­rupted block. This mid-block restart function enables sequence restart from the point where the
operation was interrupted. In addition, the order of axis movements to return to the sequence restart
point can be set by assigning the priority to the axes.

(2) Manually retract the tool from the operation interrupted point.
(3) Manually return the tool near the operation interrupted point (restart point).
(4) Start the NC by pressing the [CYCLE START] button after return search operation. The com-

mands in the located block are internally processed up to the restart point.

(5) Press the [SEQUENCE RESTART] switch. The tool is positioned at the restart point at a jog fee-

drate.

(6) Press the [CYCLE START] button. The interrupted operation is resumed from the restart point.

In the internal processing of the located block, commands are processed without actual machine
operations like the operation in the machine lock state.

[Supplement]

If manual shift amount differs before and after operation interruption, the tool returns to the point
that is displaced from the operation interrupted point by this difference.

In “return operation”, all programmed commands are executed as in normal operation with excep­tions that function generation and external outputs for S, T, and M commands are not executed. Call­ing a subprogram, return from a subprogram, coordinate system shift, etc. are all executed.
The term “block count” indicates the count data of the sequences having been executed since the
program was started after the resetting of the NC. Control statements such as GOTO and CALL are
not counted. Since the block count data and the sequence name are not cleared by resetting the or
turning ON/OFF the power, they can be used for restoring the operation after resetting the NC, etc.
They are cleared at the first starting up of the operation.

SECTION 5 WARM-UP FUNCTION

(1) After the completion of the warm-up program, the program selected last by the operation at the

operation panel is automatically selected. Therefore, if the warm-up program (file name:
W.WAF) was selected at the operation panel before shutting off the power, W.WAF is selected
again after the completion of the warm-up program.

(2) Even if the calendar timer output is turned off during the execution of the warm-up program, the

warm-up program is continuously executed.

(3) An alarm occurs if the W.WAF file does not exist in the memory when the power is automati-

cally turned on according to the setting on the calendar timer. For details, refer to “Alarm”.

(4) After the power is turned on, keys on the operation panel (mode selection keys, function keys

and alphanumeric keys), cycle start button and external cycle start button are all disabled until
the warm-up program starts automatically. These keys and buttons are operative, however, if
the warm-up program file selection is impossible.

(5) If the [RESET] button is pressed during warming up, the program having been selected before

shutting off of the power is automatically selected. Note that this automatic selection is not pos­sible if “NOT SELECT” is selected for THE PROGRAM SELECTED BEFORE THE POWER
OFF of NC optional parameter (AUTO SET AT NC RESET/POWER ON).

(6) If the calendar timer goes on after the position data is displayed on the screen with the power

turned on by an operator, the warm-up function does not operate.

(7) Completion of the warm-up program does not cause power shutoff if the automatic power shut-

off function is selected.

(8) While the warm-up program is running after the power was turned ON, “WARM-UP PROGRAM

RUNNING” is displayed.

CAUTION

If the operator turns off the power once while the calendar timer output is on and then turns it
on, the warm-up program is executed again.

3. Parameter

In relation to the warm-up function, setting is required for the following parameter.

SECTION 6 SIMPLIFIED LOAD MONITOR FUNCTION

SECTION 6 SIMPLIFIED LOAD MONITOR FUNCTION

The simplified load monitor function monitors the spindle load ratio and outputs the alarm signal if
the detected load ratio exceeds the parameter set value.
A total of five sets of parameters are used for this function and system variable VSLNO selects the
desired parameter set. M142/M143 turns the simplified load monitor function on/off.

Eeoemm6f7001

1. Setting for the Simplified Load Monitor Function

(1) Turning ON/OFF the Function

M142...Turns the simplified load monitor function ON
M143...Turns the simplified load monitor function OFF

(2) Selecting the Spindle Load Monitor Parameter Number

For monitoring the spindle load, “maximum load (LOAD MAX)”, “continuous load time (LOAD
TIMER)” and “monitor mode (MONIT. MODE)” are set for parameters and five sets of parame­ters are provided. To execute monitoring, one set of parameters must be selected in advance.
VSLNO... Monitor parameter number selection system variable
Since VSLNO is backed up, previous setting for this variable is used if VSLNO is not set for the
monitoring. If no value has ever been set for this variable, “1” is assumed.

(3) Ignoring Spindle Motor Start-up Current

At the start up of the spindle motor, the start-up current flows the motor drive circuit causing the
detected spindle load to exceed the set maximum load. To prevent the occurrence of an alarm
in this situation, the NC ignores the start-up current of the spindle motor by the two steps of pro­cessing indicated below.

Eeoemm6f7002

a) The function ignores the spindle overload state until the actual spindle speed falls within the

range 75% to 125% of the specified spindle speed (S command).

4291-E P-78

SECTION 6 SIMPLIFIED LOAD MONITOR FUNCTION

b) After the spindle speed reaches the range 75% to 125% of the specified spindle speed (S

command), the function stays immune to the spindle load for the parameter-set length of
time to allow the spindle to rotate in the stable state.

(4) Overload Monitoring Method

When the spindle reaches the constant speed and rotates in the stable state, with the monitor
parameter set by VSLNO and the monitor function turned on by M143, spindle overload monitor
begins.
If the actual spindle load exceeds the parameter set maximum load for the length of parameter
set time, the spindle overload alarm occurs.

2. Screen Display

4291-E P-79

SECTION 6 SIMPLIFIED LOAD MONITOR FUNCTION

From the function menu of the initial display screen in any operation mode, select [F3] (LOAD ON/
OFF) to display the LOAD window, monitor the spindle load in the LOAD window.
The LOAD MONITOR window can also be displayed on the “MAIN PROGRAM” and “SCHEDULE
PROGRAM” screens in each operation mode.

Eeoemm6f7003

Fig.6-2 LOAD Window

EIOEMM6F7002R01

(a) The LOAD MONITOR meter displays the load in three colors: blue (load up to the continuous

rating of the spindle motor); yellow (over the continuous rating of the spindle motor and up to the
short-time rating); red (over the short-time rating of the spindle motor). The peak state will be
maintained. The LOAD MONITOR meter is reset each time the LOAD MONITOR window
appears.

(b) “LOAD MONITOR” appears after the immune period to ignore the start-up current is terminated

during monitoring (M143), indicating overload is being monitored. If the spindle load exceeds
the maximum load, the background color of the OVERLOAD MONITOR frame changes from
green to yellow.

(c) The value displayed on the right side of “LOAD MONITOR” is the spindle overload monitor

parameter number currently selected.

(d) The value displayed on the right side of the parameter number described in c) above is the max-

imum load of the spindle overload monitor parameter currently selected.
