The speed dynamic response characteristics of the vector control can be adjusted by setting
the proportional coefficient and integration time of the speed regulator. Increasing the
proportional gain or reducing the integration time can accelerate the dynamic response of the

the integration time to ensure that the system has quick response characteristics and small
overshoot.
Caution: Improper PI parameter setting may cause too large speed overshoot. Voltage fault
may occur when the overshoot drops.
