The parameters P03.00–P03.05 are applicable
only to vector control mode. Below the
switching frequency
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.
obtained according to the linear change of
two groups of parameters. See the following

The speed loop
characteristics of vector control can be
adjusted by
coefficient and
regulator. Increasing proportional gain or
reducing integral
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 small, stable oscillation or speed offset
may occur.
PI parameters have a close relationship with
the inertia of
parameters depending on different loads to
meet various demands.
