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:

PI parameter
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;
however, if the proportional gain is too large or
integral time is too small, system oscillation and
overshoot may occur; if proportional gain is too
