P23.00–P23.05 fit for vector control mode only.
Below switchover frequency 1 (P23.02), the speed
loop PI parameters are P23.00 and P23.01. Above
switchover frequency 2 (P23.05), the speed loop
PI parameters are P23.03 and P23.04; in between
them, the PI parameters are obtained by linear
variation between two groups of parameters, as
shown in the figure below.

The speed loop dynamic response characteristics
of vector control can be adjusted by setting the
proportional coefficient and integral time of speed
regulator. Increase proportional gain or decrease
integral time can accelerate dynamic response of
speed loop, however, if the proportional gain is too
