This is a function for stopping a servo program being executed by means of a
deceleration stop caused turning the cancel signal ON. When used in combination
with "start" (selectable item), this function also allows a designated servo program
to be automatically started after a deceleration start.
(1) When the cancel signal is turned ON during execution of a program for which
the cancel function has been designated, the positioning processing being
executed is suspended, and a deceleration stop is executed.
(2) If "start" has been designated in conjunction with "cancel", after the stop has
been executed as described above, the designated servo program is started.

(2) Start (selectable item) setting method
Set by indirect designation (1 word) by using a constant (K) or D, W devices.
(1) Cannot be used with the home position return instruction (ZERO) or

instruction list (6.2(2)).

operation and the program cannot be executed, the axes decelerate to a stop
and minor error "101" occurs.
