■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 difference between "4: Slippage method (Linear)" and "5: Slippage method (Linear: Input value follow up)" is shown
below.
Input speed during
smoothing
When input speed is fixed
When there is a continuous small
oscillation in the input speed
When input speed has a large
fluctuation
• When input speed is fixed
The operation for "4: Slippage method (Linear)" and "5: Slippage method (Linear: Input value follow up)" is the same.
Clutch ON/OFF status
Clutch smoothing status
Speed before clutch processing
Speed after clutch smoothing
• When there is a continuous small oscillation in the input speed
• When "4: Slippage method (Linear)" is set
The clutch smoothing status ON section changes with the fluctuation of the input speed.
• When the clutch smoothing status ON section is extended

Smoothing method
4: Slippage method (Linear)
No difference
The output speed (smoothing section) fluctuates according
to the input speed when clutch is ON.
The fluctuation in the output speed (smoothing section) is
small. (The average speed may rise higher than before the
start of smoothing)

5: Slippage method (Linear: Input value follow
up)
The output speed (smoothing section) is fixed regardless of
the input speed when clutch is ON.
The output speed (smoothing section) fluctuates with the
input speed. (When reaccelerating after the input speed is
dropped, a sudden acceleration may occur)
