■Slippage method linear acceleration/deceleration smoothing
Set "4: Slippage method (Linear)" or "5: Slippage method (Linear: Input value follow up)" in the clutch smoothing method.
The differences between "4: Slippage method (Linear)" and "5: Slippage method (Linear: Input value follow up)" are shown
below.

When the speed is fixed
When the speed is changed
continuously and slightly
When the speed is changed largely
• When the input speed to the clutch is fixed
The operations of "4: Slippage method (Linear)" and "5: Slippage method (Linear: Input value follow up)" are same.
