Positioning control
Speed control ( , )
JOG operation
Speed control with
fixed position stop
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 is continued.
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 the error code [202] is
stored in the minor error storage register for each axis.
(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
type, execute the home position return after move to before the proximity dog ON
by the JOG operation or positioning.
