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:
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.
