0: Runs at the default direction, the VFD runs in
the forward direction. FWD/REV indicator is off.
1: Runs at the opposite direction, the VFD runs in
the reverse direction. FWD/REV indicator is on.
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 the reverse
running is disabled.

The advantage of high carrier frequency: ideal
current waveform, little current harmonic wave
and motor noise.
