High-frequency ACR
proportional coefficient
In the FVC (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 than the ACR
high-frequency switching threshold
(P03.39), the ACR PI parameters are
P03.37 and P03.38.

5.5.4 SVPWM 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.
The VFD provides multiple kinds of V/F curve modes to meet different field needs. You can select
corresponding V/F curve or set the V/F curve as needed.
Suggestions:
For the load featuring constant moment, such as conveyor belt which runs in straight line, as
the moment should be constant during the whole running process, it is recommended to adopt
straight-type V/F curve.
For the load featuring decreasing moment, such as fan and water pump, as the relation
