Deviation Counter Clear Setting - Mitsubishi Electric MELSEC Q Series User Manual

6.2.9

Deviation counter clear setting

Set whether to clear the deviation counter when Servo READY signal turns off.
If "0: Clear the deviation counter when the servo ready signal is OFF." is set, the deviation counter is cleared and OPR
request signal turns on when Servo READY signal turns off. After Servo READY signal is turned on, execute OPR
before executing the positioning control.
If "1: Do not clear the deviation counter when the servo ready signal is OFF." is set, the deviation counter is not cleared
when Servo READY signal turns off. OPR request signal does not turn on as well. When turning on Servo READY
signal after that, ensure the system safety in advance because turning on the signal may cause a sudden rotation of
the motor.
