2 POSITIONING DEDICATED SIGNALS
2.1 Internal Relays
[Rq.1140] Stop command (R: 32n/Q: M3200+20n)
• 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.)
• The details of stop processing when the stop command turns on are shown below. (Refer to Speed control (
) (
318 Speed Control (I)), or speed control (
) (
Page 321 Speed Control (II)) for details of speed control.)
• The stop command in a dwell time is invalid. (After a dwell time, the "[St.1040] Start accept flag (R: n/Q:
M2001+n)" turns OFF, and the "[St.1061] Positioning complete (R: 32n/Q: M2401+20n)" turns ON.)
If it is made to stop by turning on the "[Rq.1140] Stop command (R: 32n/Q: 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.
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.

Manual pulse generator
operation
An immediate stop is executed without deceleration
processing.
Home position return
• The axis decelerates to a stop in the deceleration time set in the parameter block.
• A stop error during home position return occurs and the minor error (error code:1908H) is stored in the "[Md.1004] Error
code (R: 48n/Q: D7+20n)" for each axis.
Speed-torque control
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.
Pressure control
Machine program operation
This decelerates to a stop in the deceleration time set in the
parameter block or machine positioning data.
The deceleration stop processing is continued.
