Gain
If the motor oscillates during light load, gradually
increase this value by units of 0.1. If the motor
stalls, gradually decrease this value by units of 0.1. Default: 2.00

n3-04 Overexcitation gain
When the excitation is decelerated, the
overexcitation degree is determined by
multiplying this parameter by the output voltage.
When the motor stops running or re-accelerates
to the frequency command speed, the output
voltage will return to the normal value.
