F2-00 and F2-01 are PI regulation parameters when the running frequency is smaller than the value of F2-02
(Switchover frequency 1).
F2-03 and F2-04 are PI regulation parameters when the running frequency is larger than the value of F2-05
(Switchover frequency 2).
If the running frequency is between F2-02 and F2-05, the speed loop PI parameters are obtained from the
weighted average value of the two groups of PI parameters (F2-00, F2-01 and F2-03, F2-04), as shown in Figure
4-1.

The speed dynamic response characteristics in vector control can be adjusted by setting the proportional gain and
integral time of the speed regulator.
To achieve a faster system response, increase the proportional gain and reduce the integral time. Be aware that
this may lead to system oscillation.
The recommended adjustment method is as follows:
The default setting meets the requirements of most applications. If the default setting cannot meet the
requirements (especially when the motor power is very small), the default speed loop proportional gain may be a
little large, and the motor oscillates at startup.
In this case, decrease the proportional gain rst to ensure that the system does not oscillate, and then reduce the
integral time to ensure that the system has quick response but small overshoot.
If both F2-02 (Switchover frequency 1) and F2-05 (Switchover frequency 2) are 0, only F2-03 and F2-04 are valid.
