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 has a close relationship with the inertia of
the system. Adjust on the base of PI according
to different loads to meet various demands.
The setting range of P03.00 and P03.03:
0~200.0
The setting range of P03.01 and P03.04:
0.000~10.000s
The setting range of P03.02: 0.00Hz~P00.05

on slip
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
control the speed steady-state error.
