(b) Slippage system
There are following two systems for slippage system.
• Exponential function system
• Linear acceleration/deceleration system
1) Exponential function system
a) Set the slippage indicated by the shaded area in the diagram below.
Slippage is recommended to be set greater than input to clutch
(travel value after the main shaft's differential gear).

Clutch status
b) Since the slippage remains constant even if the drive module speed
changes, the clutch ON/OFF position can be controlled without any
influence from speed changes.
