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" (F03.02), the speed
loop PI parameters are F03.00 and F03.01.
If the running frequency is equal to or greater than "Switchover frequency 2" (F03.05), the
speed loop PI parameters are F03.03 and F04.04.
If the running frequency is between F03.02 and F03.05, the speed loop PI parameters are
obtained from the linear switchover between the two groups of PI parameters.
