Stop Operation Of Output Axis - Mitsubishi Electric FATEC MELSEC iQ-R Training Manual

7.1.17 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.
The target axis bit of "[Cd.380] Synchronous control start" is turned from ON to OFF.

(1) Immediate stop
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.
