NOTE
1. The block of G31 command moves in the same way as
GO1. If parameter (#6019, D4) is set to “1,“ the feedrate
which is not specified in the part program but is set to
parameter #6232 is provided.
2. If SKIP input is not closed after the completion of the
block of G31 command, the following operation takes
place:
a. When setting #6004, DO is set to “ 1,“ the following
block is exe-cuted.
b. When setting #6004, DO is set to “O,” the alarm state
(alarm code “087”) is generated.
3. SKIP signal is effective, when turned off, by setting
parameter #6024, D4.
4. There is a parameter for determing enable or disable for the
skip input control circuit. To enable the skip function, set
parameter #6063, D1 to” 1.“
20.2.36 PROGRAM INTERRUPT (PINT) INPUT
This input is used to jump an NC program to be executed by the
external input to a given location during the execution of a part
program in the automatic operation mode.
When PINT input changes from open to close while the control
is executing the block between M91 and M90 commands, it
immediately discontinues this block and starts the execution of the
part program of the program number (P) specified in the block of
M91.
Note
If PINT input changes from open to close when the control is
at standstill after the execution of a block between M91 and
M90 commands on a single block basis, the execution of the
part program specified in P is started at the time the automatic
activation is performed.
20.2.37 DISPLAY RESET (DRS) INPUT
These inputs set the external 3-axis current value display (EXTER-
NAL DISPLAY) on the CRT operator’s panel to “O.” They are
used with Handle axis selection input.

20.2.38 TOOL LENGTH OFFSET (TLMI, RET, TLM O)
lNPUTS/OUTPUTS
Opening TLMI contacts stores the Z-axis current value in the
control as home position. In this case, tool length mode indicating
TLMO is outputted. Closing RET after moving Z-axis to the
measured point stores the move distance of Z-axis from the home
position in the offset memory.
Opening TLMI contact again cancels TLM mode and stops TLMO
output.
20.2.39 AXIS INTERLOCK (lTX, ITY, ITZ, ITcx)
INPUTS
Axis interlock is provided with each axis for inhibiting axis motion.
(1) When axis interlock contact is opened during motion, the axis is
coasted to stop. Closing the interlock will resume the remain-
ing operation interrupted by opening the interlock contact.
When the remaining operation is completed, operation will
advance to the next block.
(2) For simultaneous controlled two axes or three axes in inter-
polation command, opening the axis interlock contact for any
one axis of them stops interpolation and decelerates the axis to
stop.
20.2.40 PLAYBACK (PLYBK) INPUT
To put the control in the Playback mode, close the playback input
in the manual operatiom mode (HANDLE, STEP, JOG, RAPID) .
In the Playback mode, current value for each axis can be edited by
PROGRAM function key. Usual manual operation is also permit-
ted. Open the Playback input contact and usual manual operation
mode is obtained.
