2 STARTING UP THE SYSTEM
2.2 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 (n) ON/OFF.
