P03 Group Vector control
Speed The parameters P03.00~P03.05 only apply to vector
loop control mode. Below the switching frequency
P03.00
proportion 1(P03.02), the speed loop PI parameters are:
al gain1 P03.00 and P03.01. Above the switching frequency
2(P03.05), the speed loop PI parameters are:
Speed
P03.03 and P03.04. PI parameters are gained
loop
P03.01
according to the linear change of two groups of
integral
parameters. It is shown as below:

performance of vector control speed loop. Increasing
integral
the proportional gain and decreasing the integral
time 2
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.

different loads to meet various demands.
The setting range of P03.00: 0.0~200.0
The setting range of P03.01: 0.000~10.000s
The setting range of P03.02: 0.00Hz~P03.05
The setting range of P03.03: 0.0~200.0
