P03.02
Low switching
frequency
gained according to the linear change of two groups of
parameters. It is shown as below:
Setting the proportional coefficient and integral time of the
adjustor can change the dynamic response performance of
vector control speed loop. Increasing the proportional gain
and decreasing the integral time can speed up the dynamic
response of the speed loop. But too high proportional gain
and too low integral time may cause system vibration and
overshoot. Too low proportional gain may cause system
vibration and speed static deviation.
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: 0~200.0

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.

Note 1 : 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.
Note 2 : Only apply to SVC control mode 0 (P00.00=0).
