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

5.5.4 Space voltage vector control mode
The VFD also provides the space voltage control function. The space voltage control mode can be
used in cases where mediocre control precision is enough and in cases where the VFD needs to
drive multiple motors.
The VFD provides multiple V/F curve modes to meet different requirements. You can select V/F
curves or set V/F curves as required.
