In the closed-loop vector control mode
(P00.00=3), when the frequency is lower
than the ACR high-frequency switching
threshold (P03.39), the ACR PI parameters
are P03.09 and P03.10; and when the
frequency is higher
high-frequency switching
(P03.39), the ACR PI parameters are
P03.37 and P03.38.
Setting range of P03.37: 0–20000
