3.1.2 Axis command signals
(1) Stop command (M3200+20n)
(a) The stop command is a signal used to stop an axis that is currently being
driven and becomes effective at its leading edge (OFF→ON). (An axis for
which the stop command is ON cannot be started.)
OFF
ON
Set speed
V
Stop command for
designated axis
Deceleration processing
Stop
Control when sto
command is OFF
t
Stop command
(M3200+20n)
(b) It can also be used as the stop command when speed control is being
executed.
(For details on speed control, see Section 7.12 or Section 7.13.)
Processing when the Stop Command Comes ON
Control Being
Executed
If Control is Being Executed
If Deceleration Stop Processing is
Being Executed
Position control
Speed control (I, II)
JOG operation
The axis decelerates to a stop in the
deceleration time set in the parameter
block or servo program.
The stop command is ignored and
deceleration stop processing
continues.
Manual pulse
generator operation
An immediate stop is executed, with
no deceleration processing.

Zeroing
(1) The axis decelerates to a stop in the deceleration time set in the
parameter block.
(2) A "stop during zeroing" error occurs and the error code (202) is stored in
the minor error storage area for each axis.
POINT
If a stop is executed by turning ON the stop command (M3200+20n) during a
zeroing operation, re-execute the zeroing operation.
If the stop command came ON after the proximity dog came ON in the zeroing
operation, first retract to a position before the point where the proximity dog
comes ON using JOG operation or positioning, and then execute the zeroing
operation again.
