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, the current-loop PI
parameters are P03.37 and P03.38.
P03.37 setting range: 0–20000

5.5.4 Space voltage vector control mode
The VFD also carries built-in SVPWM control function. SVPWM mode can be used in cases where
mediocre control precision is enough. In cases where a VFD needs to drive multiple motors, it is also
recommended to adopt SVPWM control mode.
