Set the clutch smoothing method in "[Pr.411] Main shaft clutch smoothing method (R: D42658+160n/Q: D15018+150n)" and
"[Pr.428] Auxiliary shaft clutch smoothing method (R: D42680+160n/Q: D15040+150n)".
The 2 types of clutch smoothing include the following.
• Time constant method smoothing
• Slippage method smoothing
When not using clutch smoothing, set "0: Direct" in the clutch smoothing method.

The operation of each smoothing method is shown below.
Time constant method smoothing
Smoothing is processed with the time constant setting value in the smoothing time constant at clutch ON/OFF. After clutch ON
smoothing is complete, smoothing is processed with the time constant setting value when the speed of the input values
changes.
The travel value between the clutch turning ON and OFF is not changed with smoothing.
Travel value after clutch smoothing = Travel value before clutch smoothing
