(V2, F2), and (V3, F3) three-point line, to
adapt to special load characteristics.
2. This function parameter group is used
to flexibly set the V/F curve required by
the user.
Note: V1<V2<V3, F1<F2<F3, setting
the low-frequency voltage too high may
cause the motor to overheat or even get
burned, and the drive may also have
overcurrent stall or overcurrent
protection. It shall be set according to
the load characteristics of the motor.

The direction of the motor can be changed
by changing this function code. Its
function is equivalent to changing the
direction of rotation of the motor by
adjusting any two lines of the motor lines
U, V, and W.
Note: After the function code
parameters are restored to the factory
setting, the motor running direction
will be restored to the factory value.
Use with caution on the occasions that
it is forbidden to change the motor
steering after system debugging.

1. Advantages of high carrier frequency:
Ideal current waveform, less current
harmonics, and low motor noise.
2. Disadvantages of high carrier
frequency: The switching loss increases,
the drive temperature rises and the output
ability of the drive is affected. Under high
carrier frequency, the drive needs to be
derated; at the same time, the leakage
current of the drive increases, and the
external electromagnetic interference
increases.
3. The use of low carrier frequency is
contrary to the above situation. Too low
carrier frequency will cause low
frequency operation instability, torque
decrease and even oscillation.
4. When the drive leaves the factory, the
manufacturer has set the carrier frequency
reasonably. Generally, users do not need
