Axis Command Signals - Mitsubishi Electric Q172CPU Programming Manual

5 POSITIONING DEDICATED SIGNALS

5.1.2 Axis command signals

(1) Stop command (M3200+20n)
(a) This command stops a starting axis from an external source and becomes
effective at the turning signal off to on. (An axis for which the stop command
is turning on cannot be started.)
Stop command OFF
(M3200+20n)
V
Setting speed
(b) The program is ended by the stop command at the automatic start by the
SVST instruction. (The Motion program is stopped if any of the stop
commands for the axis No. specified with the SVST instruction turns on.)
(c) The re-start command (M4404+10n) is valid only after the temporary stop
command (M4400+10n).
(d) The details of stop processing when the stop command turns on are shown
below.
Control details
during execution
Positioning control The axis decelerates to a stop in the
during the Motion deceleration time set in the parameter
program start block or Motion program.
JOG operation
Manual pulse An immediate stop is executed without
generator operation deceleration processing.
(1) The axis decelerates to a stop in the deceleration time set in the parameter
block.
Home position return
(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.
(Note-1) : The deceleration time under G00, G01, G02, G03, G12, G13 or G32 including M-code is
equivalent to the acceleration time set in the parameter block.
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.
