(a) This command is a signal which stop a starting axis rapidly from an external
source and becomes effective when the signal turns off to on. (An axis for
which the rapid stop command turns on cannot be started.)

The axis decelerates to a rapid stop
deceleration time set in the parameter
block or servo program.
Deceleration processing is canceled and
rapid stop processing executed instead.
Manual pulse
generator operation
An immediate stop is executed without
deceleration processing.
Home position return
(1) The axis decelerates to a stop in the rapid stop deceleration time set in the
parameter block.
(2) A "stop error during home position return" error occurs and the error code [203] is
stored in the minor error storage register for each axis.
(c) The rapid 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 rapidly by turning on the rapid stop command (M3201+20n)
during a home position return, execute the home position return again.
If the rapid stop command turned on after the proximity dog ON in the proximity dog
type, execute the home position return after move to before the proximity dog ON
by the JOG operation or positioning.
