(2) 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.
