Starting/Ending For Synchronous Control - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Starting/Ending for Synchronous Control

Set the parameters for synchronous control for each output axis to start synchronous control.
The status changes to synchronous control after the parameters are analyzed at the start of synchronous control, and the
output axes synchronize with input axis operations.
The advanced synchronous control is started/ended by the operation of "[Rq.380] Synchronous control start (R: M43440+n/Q:
M12000+n)" ON/OFF.

Setting value
• Synchronous control OFF: Synchronous
begins if the target axis bit
device is turned ON. ON: Synchronous
• Synchronous control ends
if the bit device is turned
OFF during synchronous
control.
If the target axis bit device is OFF: Synchronous
turned ON and synchronous
control is started, the analysis
is only executed and the ON: Synchronous
control does not start.
