OPERATION

4. AUTOMATIC OPERATION

D Single block

When single block operation is ON during movement to the restart

position, operation stops every time the tool completes movement along

an axis. When operation is stopped in the single block mode, MDI

intervention cannot be performed.

D Manual intervention

During movement to the restart position, manual intervention can be used

to perform a return operation for an axis if it has not yet been performed

for the axis. A return operation cannot be done further on axes for which

a return has already been completed.

D Reset

Never reset during the time from the start of a search at restart until

machining is restarted. Otherwise, restart must be performed again from

the first step.

D Manual absolute

Regardless of whether machining has started or not, manual operation

must be performed when the manual absolute mode is on.

D Reference position return

If no absolute-position detector (absolute pulse coder) is provided, be

sure to perform reference position return after turning on the power and

before performing restart.

Alarm

Alarm No.

Contents

The specified block number for restarting the program is not

071

found.

After interruption, a coordinate system was set, then P-type

094

restart was specified.

After interruption, the coordinate system shift was changed,

095

then P-type restart was specified.

After interruption, the coordinate system was changed, then

096

P-type restart was specified.

When automatic operation has not been performed since

the power was turned on, emergency stop was released, or

097

P/S alarm 094 to 097 was reset, P-type restart was speci-

fied.

After the power was turned on, restart operation was per-

098

formed without reference position return, but a G28 com-

mand was found in the program.

A move command was specified from the MDI panel during

099

a restart operation.

An erroneous parameter was specififed for restarting a pro-

5020

gram.

WARNING

As a rule, the tool cannot be returned to a correct position under the following conditions.

Special care must be taken in the following cases since none of them cause an alarm:

S Manual operation is performed when the manual absolute mode is OFF.

S Manual operation is performed when the machine is locked.

S When the mirror image is used.

S When manual operation is performed in the course of axis movement for returning operation.

S When the program restart is commanded for a block between the block for skip cutting and

subsequent absolute command block.

4. AUTOMATIC OPERATION

The subprogram call function is provided to call and execute subprogram

files stored in an external input/output device(Handy File, FLOPPY

CALL FUNCTION

When the following block in a program in CNC memory is executed, a

(M198)

subprogram file in the external input/output device is called:

Format

1. FS10/11 tape format

M198 Pffff L∆∆∆∆ ;

2. Other than FS10/11 tape format

M198 Pffff ∆∆∆∆ ;

File number for a file

in the I/O device

Number of repetitions

I/O devices call instruction

Explanation

The subprogram call function is enabled when parameter No.0102 for the

input/output device is set to 3. Either format 1 or 2 can be used. A different

M code can be used for a subprogram call depending on the setting of

parameter No.6030. In this case, M198 is executed as a normal M code.

The file number is specified at address P. If the SBP bit (bit 2) of parameter

No.3404 is set to 1, a program number can be specified. When a file

number is specified at address P, Fxxxx is indicated instead of Oxxxx.

NOTE

When M198 in the program of the file saved in a floppy

cassette is executed, a P/S alarm (No.210) is given. When

a program in the memory of CNC is called and M198 is

executed during execution of a program of the file saved in

a floppy cassette, M198 is changed to an ordinary M-code.

When MDI is intervened and M198 is executed after M198

is commanded in the memory mode, M198 is changed to an

ordinary M-code. When the reset operation is done in the

MDI mode after M198 is commanded in the MEMORY

mode, it does not influence on the memory operation and

the operation is continued by restarting it in the MEMORY

mode.

D Handle interruption axis selection signals

For the handle interruption axis selection signals, refer to the manual

supplied by the machine tool builder.

During automatic operation, handle interruption is enabled for an axis

if the handle interruption axis selection signal for that axis is on.

Handle interruption is performed by turning the handle of the manual

pulse generator.

WARNING

The travel distance by handle interruption is determined

according to the amount by which the manual pulse

generator is turned and the handle feed magnification (x1,

x10, xM, xN).

Since this movement is not accelerated or decelerated, it is

very dangerous to use a large magnification value for

handle interruption.

The move amount per scale at x1 magnification is 0.001 mm

(metric output) or 0.0001 inch (inch output).

NOTE

Handle interruption is disabled when the machine is locked

during automatic operation.

return function, the switches on the operator’s panel must be used in

conjunction with the MDI keys. This function does not require such

operations.

Before this function can be used, MIN (bit 0 of parameter No. 7001) must

be set to 1.

Explanations

D Manual absolute on/off

In manual absolute off mode, the tool does not return to the stop position,

but instead operates according to the manual absolute on/off function.

D Override

For the return operation, the dry run feedrate is used, and the jog feedrate

override function is enabled.

D Return operation

Return operation is performed according to positioning based on

nonlinear interpolation.

D Single block

If the single block stop switch is on during return operation, the tool stops

at the stop position and restarts movement when the cycle start switch is

pressed.

D Cancellation

If a reset occurs or an alarm is issued during manual intervention or the

return operation, this function is cancelled.

D MDI mode

This function can be used in the MDI mode as well.

Procedure for Machine Lock and Auxiliary Function Lock

D Machine Lock

Press the machine lock switch on the operator’s panel. The tool does not

move but the position along each axis changes on the display as if the tool

were moving.

Some machines have a machine lock switch for each axis. On such

machines, press the machine lock switches for the axes along which the

tool is to be stopped. Refer to the appropriate manual provided by the

machine tool builder for machine lock.

WARNING

The positional relationship between the workpiece

coordinates and machine coordinates may differ before and

after automatic operation using machine lock. In such a

case, specify the workpiece coordinate system by using a

coordinate setting command or by performing manual

reference position return.

D Auxiliary Function Lock

Press the auxiliary function lock switch on the operator’s panel. M, S, T

Procedure for Feedrate Override

Set the feedrate override dial to the desired percentage (%) on the machine

operator’s panel, before or during automatic operation.

On some machines, the same dial is used for the feedrate override dial and

jog feedrate dial. Refer to the appropriate manual provided by the

machine tool builder for feedrate override.
