P03 Group--Vector Control - INVT Goodrive3000 Series Operation Manual

Goodrive3000 series medium voltage VFD
variable-frequency motor is not impacted by the rotation speed, it is not necessary to adjust the protection value at low
speed running.

The parameters P03.00–P03.05 are applicable only to vector control mode. Below the switching frequency 1 (P03.02), the
speed-loop PI parameters are: P03.00 and P03.01. Above the switching frequency 2 (P03.05), the speed-loop PI
parameters are: P03.03 and P03.04. PI parameters are obtained according to the linear change of two groups of
parameters. See the following figure:
The speed loop dynamic response characteristics of vector control can be adjusted by setting the proportional coefficient
and integral time of speed regulator. Increasing proportional gain or reducing integral time can accelerate dynamic
