integral time1 switching frequency 2 ( E03.05 ), the speed loop EI
parameters are: E03.03 and E03.04 . EI
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.

Compensation
coefficient of
electro motion
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.
