AUTO INTERLOCK

(+) nTH AXIS
[Function]
All axis motions of machine can be decelerated and stopped immediately during automatic
operation when motion of a specific axis (nth axis) in plus direction activates the interlock function.
These signals are for each control axis, and the number at the end of the signal name indicates the
control axis No.

[Operation]
When this signal turns OFF for a specific axis in motion in the plus direction under automatic
operation mode (memory, MDI), motion of all axis decelerates and stops with "M01 operation error
code 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 resumes or starts axis motion.
[Related signals]
Auto interlock, (-) nth axis (Y446)
Manual interlock, (+)/(-) nth axis (Y447/Y448)
[Cautions]
(1) All automatic interlock signals are for B contact.
(2) In C6/C64, the automatic 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.

AUTO INTERLOCK
*
( − ) nTH AXIS
[Function] [Operation]
The details are the same as the automatic interlock +nth axis, except that the direction is opposite.
The automatic 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.
