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 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
DRV-28 inverter also carries built-in SVPWM control function. SVPWM mode can be used in cases
where mediocre control precision is enough. In cases where an inverter needs to drive multiple
motors, it is also recommended to adopt SVPWM control mode.
DRV-28 inverter provides multiple kinds of V/F curve modes to meet different field needs. Users can
select corresponding V/F curve or set the V/F curve as needed.
Suggestions:
1.
For the load featuring constant moment, eg, 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.
2.
For the load featuring decreasing moment, eg, fan and water pump, as the relation
