The parameters P03.00
–P03.05 only apply 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 gained according to the linear
change of two groups of parameters. It is shown
as below:

PI parameter
PI has a close relationship with the inertia of the
system. Adjust on the base of PI according to
different loads to meet various demands.

electromotion
Slip compensation coefficient is used to adjust
the slip frequency of the vector control and
improve the speed control accuracy of the
system. Adjusting the parameter properly can
