Clutch

Overview of clutch

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

Control method for clutch

Set the ON and OFF control methods separately in "[Pr.405] Main shaft clutch control setting (R: D42648+160n/Q:
D15008+150n)" and "[Pr.422] Auxiliary shaft clutch control setting (R: D42670+160n/Q: D15030+150n)".
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.
