■Time constant method linear acceleration/deceleration smoothing
Set "2: Time constant method (Linear)" in the clutch smoothing method.

Slippage method smoothing
Smoothing is processed with the value in slippage at clutch ON when the clutch turns ON, and with slippage at clutch OFF
when the clutch turns OFF.
Smoothing is also processed with the slippage amount setting when the input speed to the clutch changes, therefore,
positioning control at clutch ON/OFF is not affected by speed changes.
Processing proceeds with direct operation after completing clutch ON smoothing.
The travel value between the clutch turning ON and OFF is as follows after clutch smoothing.
Travel value after clutch smoothing=Travel value before clutch smoothing+(Slippage amount at OFF-Slippage amount at ON)
