3 POSITIONING DEDICATED SIGNALS
3.1.2 Axis command signals
(1) Stop command (M3200+20n) ................................ Command signal
(a) This command is a signal which stop a starting axis from an external source
and becomes effective at leading edge of signal. (An axis for which the stop
command is turning on cannot be started.)

(b) The details of stop processing when the stop command turns on are shown
below. (Refer to Section 6.13 or 6.14 for details of the speed control.)
Control details
during execution
Processing at the turning stop command on
During control During deceleration stop processing
Positioning control
The axis decelerates to a stop in the
deceleration time set in the parameter
block or servo program.
The deceleration stop processing is
continued.
Speed control ( )
Speed control ( )
JOG operation
Speed control with
fixed position stop
Manual pulse
generator operation
An immediate stop is executed without
deceleration processing.
—
Home position return
(1) The axis decelerates to a stop in the deceleration time set in the parameter
block.
(2) A "stop error during home position return" occurs and minor error (error code:
202) is stored in the minor error storage register (D6+20n) for each axis.
Speed-torque control
QDS
The speed commanded to servo
amplifier is "0". The mode is switched to
position control mode when "Zero
speed" turns ON, and the operation
stops.
—
(c) The stop command in a dwell time is invalid. (After a dwell time, the start
accept flag (M2001+n) turns OFF, and the positioning complete signal
(M2401+20n) turns ON.)
POINT
If it is made to stop by turning on the stop command (M3200+20n) during a home
position return, execute the home position return again.
If the stop command is turned on after the proximity dog ON in the proximity dog
method, execute the home position return after move to before the proximity dog
ON by the JOG operation or positioning.
