The speed dynamic response characteristics in vector control can be adjusted by setting the
proportional gain and integral time of the speed loop controller.
The larger proportional gain (Kp) the faster response will be. However, system may be
unstable when Kp is too large.
The less integral time (Ki) the faster response will be. However, system may be unstable
when Ti is too small.
If the running frequency is less than or equal to "Switchover frequency 1" (d2.04), the
speed loop controller parameters are d2.00 and d2.01.
If the running frequency is equal to or greater than "Switchover frequency 2" (d2.05),
the speed loop controller parameters are d2.02 and d2.03.
If the running frequency is between d2.04 and d2.05, the speed loop PI parameters
