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
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

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.
2. Only apply to the vector control mode without PG
0 (P00.00=0).
