V/F slip compensation gain

☆
This parameter is valid only for the asynchronous motor.
It can compensate the rotational speed slip of the asynchronous motor when the load of the motor
increases, stabilizing the motor speed in case of load change.
If this parameter is set to 100%, it indicates that the compensation when the motor bears rated load
is the rated motor slip. The rated motor slip is automatically obtained by the Inverter through calculation
based on the rated motor frequency and rated motor rotational speed in group P1.
Generally, if the motor rotational speed is different from the target speed, slightly adjust this
parameter.
P2.10
V/F over-excitation gain
0~200
64
☆
During deceleration of the Inverter, over-excitation can restrain rise of the bus voltage, preventing the
overvoltage fault. The larger the over-excitation is, the better the restraining result is.
Increase the over-excitation gain if the Inverter is liable to overvoltage error during deceleration.
However, too large over-excitation gain may lead to an increase in the output current. Set P2.09 to a
proper value in actual applications.
Set the over-excitation gain to 0 in the applications where the inertia is small and the bus voltage will
not rise during motor deceleration or where there is a braking resistor.
P2.11
V/F oscillation suppression
gain

-
☆
Set this parameter to a value as small as possible in the prerequisite of efficient oscillation
suppression to avoid influence on V/F control.
