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 movement amount between the clutch turning ON and OFF is not changed with smoothing.
Movement amount after clutch smoothing = Movement amount before clutch smoothing
