P2-10 Flux Brake Gain 0
～
200 100
☆
This parameter can suppress the bus voltage rise during the deceleration process of the inv-
erter. The larger the value, the better the suppression effect.
The magnetic flux braking is to increase the motor terminal current by increasing the output
voltage of the inverter, thereby improving the consumption capacity of the feedback energy
and suppressing the rise of the bus voltage. The greater the gain, the greater the motor curr-
ent, so please pay attention in the application. It is recommended to set this value to 0 when
there is a braking resistor at the same time, otherwise an abnormality may occur due to the
large deceleration current during deceleration.

P2-11 Oscillation suppression gain 0 ～ 100
Model is
determined
☆
This parameter is used to suppress motor vibration. When the motor oscillates, please incre
-
ase the value appropriately, but try to set it as small as possible when the motor does not os
-
cillate, so as not to have too much influence on the V/F operation. Under normal circumstan
-
ces, no modification is required.

VF slip compensation time
constant
0.02s ～ 1.00s 0.30s
☆
This parameter is used to set the slip compensation time constant. Decreasing this value can
enhance the response speed, but the speed fluctuation may increase. Increasing this value
increases speed stability, but reduces responsiveness. Under normal circumstances, no mod-
ification is required.
