Stop Operation Of Output Axis - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

2.3

Stop Operation of Output Axis

If the following causes occur in stopping the output axis during synchronous control, "[St.380] Synchronous control (R:
M40000+n/Q: M10880+n)" turns OFF, and stops processing for the output axis is completed. After that, the "[St.1040] Start
accept flag (R: M30080+n/Q: M2001+n)" turns OFF, and the synchronous control is completed. Synchronous alignment must
be executed for the output axis to restart the synchronous control. (Page 143 Synchronous Control Initial Position)
Stop cause
"[Rq.380] Synchronous control start (R: M43440+n/Q: M12000+n)" is turned from ON to OFF.
Main shaft gear/auxiliary shaft gear/speed change gear 1/speed change gear 2 operation overflow error
occurrence
Forced stop (Motion controller forced stop (Device)
Forced stop (Forced input terminal of servo amplifier)
Servo error occurrence
Servo amplifier control circuit power supply is turned from ON to OFF.
Software stroke limit error occurrence
External input signal (STOP/FLS/RLS) input (Deceleration processing on STOP input: Deceleration stop)
The Motion CPU is turned from RUN to STOP
Stop command input
External input signal (STOP/FLS/RLS) input (Deceleration processing on STOP input: Rapid stop)
Rapid stop command input
Immediate stop
The operation stops without decelerate. The Motion CPU immediately stops the command, but the operation will coast for the
droop pulses accumulated in the deviation counter of the servo amplifier.
