Servo Program Cancel
////
Start Function
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
.
[[[[
Control details
]]]]
(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
.
[[[[
Data setting
]]]]
(1) Cancel signal device
The devices that can be used as cancel signal devices are indicated below
.
X, Y, M, TC, TT, CC, CT, B, F
(2) Start (selectable item) setting method
Set by indirect designation (1 word) by using a constant (K) or D, W devices
.
[[[[
Notes

(1) Cannot be used with the home position return instruction (ZERO) or
simultaneous start instruction (START)
.
For details on whether other instructions can be used or not, refer to the servo
instruction list (6
