Chapter 4 Synchronous Control
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.
