Description
The parameters P23.00–P23.05
only to vector control mode. Below the switching
frequency 1 (P23.00), the speed-loop PI
parameters are: P23.00
switching frequency 2 (P23.05), the speed-loop
PI parameters are: P23.03
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 response of speed loop;
