Stop Operation Of Output Axis - Mitsubishi Electric Q173DSCPU Programming Manual

2 STARTING UP THE SYSTEM

2.3 Stop Operation of Output Axis

Immediate stop cause
[Rq.380] Synchronous control
start (M12000+n)
[St.380] Synchronous control
(M10880+n)
Start accept flag (M2001+n)
[Md.407] Cam axis current value
per cycle
(D13612+30n, D13613+30n)
Current feed value
(D0+20n, D1+20n)
Command speed
(#8004+20n, #8005+20n)
If the following causes occur in stopping the output axis during synchronous control,
[St.380] Synchronous control (M10880+n) turns OFF, and stops processing for the
output axis is completed. After that, the start accept flag (M2001+n) turns OFF, and the
synchronous control is completed.
Synchronous alignment must be executed for the output axis to restart the
synchronous control. (Refer to Section 8.4.)
[Rq.380] Synchronous control start (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 (EMI connector, System setting)
Forced stop (Forced input terminal of servo amplifier)
Servo error occurrence
Servo amplifier power supply is turned from ON to OFF.
Software stroke limit error occurrence
External input signal (STOP/FLS/RLS) input
(Stop processing on STOP input: Deceleration stop)
The Motion CPU is turned from RUN to STOP
The PLC ready flag (M2000) is turned from ON to OFF.
Stop command input
External input signal (STOP/FLS/RLS) input
(Stop processing on STOP input: Rapid stop)
Rapid stop command input
(1) 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.
