inactive only at the time of
deceleration
In the V/F control mode, when it needs fast stop and there is no brake resistor,
selecting ‘inactive only at the time of deceleration can greatly reduce the possibility
of over voltage fault alarm. When there is brake resistor or it has not need for fast
deceleration, select “active”

Select “0” for this gain when the motor has no oscillation. Only when the motor has
obvious oscillation and cannot run normally can this gain be properly increased. The
bigger than gain is, the better oscillation suppression result will be. The method of
selecting this gain is to select the smallest one on the premise that there is effective
oscillation suppression measure, so as to ease the negative effect on the VF
operation.

In the process of no-load or light load running, the motor can properly adjust output
voltage so as to reach the purpose of auto-energy saving by the test of load current .
This feature is active for loads such as fan and pump
