PUTS
These input signals are for signifying the arrival of the machine slides to their respective stroke
ends,
When these overtravel input contacts are opened, the machine slides stop motion as
shown in Table. 20.23, and close the alarm (ALM) output contact and at the same time, display
an alarm on the CRT.

When an overtravel input contact is opened, move the machine in the reverse direction in
the manual operation mode (manual jogging or manual pulse generator) to close the contact,
and then, make the RESET operation to clear the alarm output and display.
NOTE
1. Even when the overtravel input contacts are opened, the M code
reading output MFA, (S) code reading output SF, and the T code read-
ing output TF are not turned off.
If the motion by M codes, S codes
or T codes is required to be stopped by inputs, inter-
lock the motion with external sequence.
2. In the event of overtraveling, an alarm between No. 2001 and No.
2005 is issued. In this situation, the axis stops (the servo system does
not turn OFF).
20.2.54 AXIS INTERLOCK ( ITX #30780 TO IT5 # 30784) INPUTS
Axis interlock is provided with each axis for prohibiting axis motion
When axis interlock contact is opened during motion, the axis is decelerated to a stop.
Closing the interlock will resume the remaining operation interrupted by opening the interlock
contact. When the remaining operation is completed, operation will advance to the next block.
(2) For simultaneous control of two axes or three axes in interpolation command, opening the
axis interlock contact for any one axis stops interpolation and decelerates the axis to a stop.
NOTE: Even if this input is opened in the cycle start process, the STL remains ON.
