Additional flux during braking/regen
Setting 0 means function is disabled. This parameter helps in reducing the noise in the lift car when the motor brake is applied due to the immediate removal of current. Increasing this value reduces audible noise, setting too high can result in reduced torque and rollback during stopping.
This parameter has no effect when operating in an IM control mode (P4-01 = 0 or 1) and the torque reduction time is fixed at 100ms.
