motor. This effect equals to the shifting the rotation direction
by adjusting either two of the motor lines (U, V and W). The
motor rotation direction can be changed by QUICK/JOG on
the keypad. Refer to parameter P07.02.
Note: When the function parameter comes back to the
default value, the motor’s running direction will come back
to the factory default state, too. In some cases it should be
used with caution after commissioning if the change of
rotation direction is disabled.
2: Forbid to run in reverse direction: It can be used in some
special cases if the reverse running is disabled.

Carrier
frequency
setting
The relationship table of the motor type and carrier
frequency:
Motor type Factory setting of carrier frequency
0.4~11kW 8kHz
15~110kW 4kHz
The advantage of high carrier frequency: ideal current
waveform, little current harmonic wave and motor noise.
The disadvantage of high carrier frequency: increasing the
switch loss, increasing inverter temperature and the impact
to the output capacity. The inverter needs to derate on high
carrier frequency. At the same time, the leakage and
electrical magnetic interference will increase.
Applying low carrier frequency is contrary to the above, too
low carrier frequency will cause unstable running, torque
decreasing and surge.
The manufacturer has set a reasonable carrier frequency
when the inverter is in factory. In general, users do not need
to change the parameter.
