Stop Operation Of Output Axis - Mitsubishi Electric QD77MS User Manual

1.4.3 Stop operation of output axis

If the following causes occur in stopping the output axis during synchronous control,
synchronous control is completed after stops processing for the output axis (BUSY signal is
OFF, axis operation status is standby).
Synchronous alignment must be executed for the output axis to restart the synchronous
control. (Refer to Section 4.5)
The target axis bit of "[Cd.380] Synchronous control start" is turned from ON to OFF.

(Stop with hardware stroke limit or stop command)
The operation stops without decelerate. The Simple Motion module immediately stops
the command, but the operation will coast for the droop pulses accumulated in the
deviation counter of the servo amplifier.
