Speed loop PI parameters vary with running frequencies of the AC drive.
•
If the running frequency is less than or equal to "Switchover frequency 1" (P2-02), the speed
loop PI parameters are P2-00 and P2-01.
•
If the running frequency is equal to or greater than "Switchover frequency 2" (P2-05), the speed
loop PI parameters are P2-03 and P2-04.
•
If the running frequency is between P2-02 and P2-05, the speed loop PI parameters are
obtained from the linear switchover between the two groups of PI parameters, as shown in Figure
5-2.

The speed dynamic response characteristics in vector control can be adjusted by setting the
proportional gain and integral time of the speed regulator.
