Detailed instruction of parameters
Modify the function code to shift the rotation direction
of the 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 reverse running is disabled.

The advantage of high carrier frequency: ideal
current waveform, little current harmonic wave and
motor noise.
The disadvantage
increasing the switch
temperature and the impact to the output capacity.
