MANUAL INTERLOCK

(+) nTH AXIS
[Function]
When the corresponding axis is moving in the plus direction with manual operation (jog, manual,
incremental, reference point return), only the corresponding axis can be decelerated and stopped
by turning OFF this signal that corresponds to that axis.
These signals are for each control axis, and the number at the end of the signal name indicates the
control axis No.

14 : Manual interlock (+) 14th axis
[Operation]
When this signal turns OFF (0) for a specific axis in motion in the plus direction under manual
operation mode (jog, handle, incremental, reference point return), motion of the axis decelerates
and stops with NC alarm "M01 OPERATION ERROR 0004" displayed. With this signal set OFF
from the beginning, the system completes calculation for axis motion but makes it remain stopped
with the same operation error code displayed. In either case, setting the signal on (1) resumes or
starts axis motion.
[Related signals]
Manual interlock, (-) nth axis (Y448)
Auto interlock, (+)/(-) nth axis (Y445/Y446)
[Cautions]
(1) All interlock signals are for B contact.
(2) In C6/C64, the "Manual interlock" signal is set to 1 when the power is turned ON, so an interlock
cancel state in the sequence program does not need to be created for the axis not being used.

MANUAL INTERLOCK
*
(-) nTH AXIS
[Function] [Operation]
The details are the same as the "Manual interlock +nth axis", except that the direction is opposite.
The "Manual interlock +nth axis" signal is valid for the axis moving in the plus direction, and this
signal is valid for the axis moving in the minus direction.
These signals are for each control axis, and the number at the end of the signal name indicates the
control axis No.
