4.3 Clutch

4.3.1 Overview of clutch

The clutch is used to transmit/disengage command pulses from the main/auxiliary shaft input
side to the output axis module through turning the clutch ON/OFF, which controls the
operation/stop of the servomotor.
A clutch can be configured for the main and auxiliary shafts.

4.3.2 Control method for clutch

and "[Pr.422] Auxiliary shaft clutch control setting".
Although the clutch control setting can be changed during synchronous control, however, the
setting "No clutch" (Direct coupled operation) cannot be selected during synchronous control
after already selecting another setting.
