oscillation, decrease the value of this parameter properly.
If the value of this parameter is small, the output torque of the AC drive may fluctuate
greatly, but the response is quick.

)2-08 Ve
ctor control over-excitation gain 0–200 64
During deceleration of the AC drive, over-excitation control can restrain rise of the bus
voltage to avoid the overvoltage fault. The larger the over-excitation gain is, the better the
restraining effect is.
Increase the over-excitation gain if the AC drive is liable to overvoltage error during
deceleration. Too large over-excitation gain, however, may lead to an increase in output
current. Therefore, set this parameter to a proper value in actual applications.
Set the over-excitation gain to 0 in applications of small inertia (the bus voltage will not rise
during deceleration) or where there is a braking resistor.
