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

control
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.
