P03.02
Low switching
frequency
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
The setting range of P03.05: P03.02~P00.03

Compensation
coefficient of
vector control
electromotion
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.
Setting range:50%~200%

Note:
These two parameters adjust the PI adjustment parameter
of the current loop which affects the dynamic response
speed and control accuracy directly. Generally, users do not
need to change the default value;
Only apply to the vector control mode without PG 0
(P00.00=0).
