0: Run in default direction: the VFD runs in forward direction. FWD/REV LED is off.
1: Run in opposite direction: the VFD runs in reverse direction. FWD/REV LED is on.
The rotation direction of the motor can be shifted by changing the function code. The effect is equivalent
to the switchover of the rotation directions by adjusting arbitrary two motor lines (U, V and W). When the
running channel is set under the keypad control, the rotation direction can be changed by QUICK/JOG on
the keypad. Refer to P07.02 (P07.02=3) for detailed information.
Note: After the function parameter returns to the default value, the running direction of the motor will
restore to the factory default state. It should be used with caution in the cases where the rotation direction
of the motor cannot be changed after commissioning.
2: Forbid reverse running: forbid the VFD to run in reverse direction. It is suitable in special cases
forbidding reverse running.

Noise and leakage
current
The advantages of the high carrier frequency: ideal current waveform, little current harmonic and motor
noise;
The disadvantages of the high carrier frequency: The switch loss and temperature of the VFD increase,
so the output ability of the VFD is affected. Under the high carrier frequency, the VFD is used by derating.
Simultaneously, the leakage current increase of the VFD causes more electromagnetic interference to
the environment.
Applying low carrier frequency is contrary to the above. Too low carrier frequency will cause unstable
running, torque decreasing and even oscillation. The manufacturer has set proper carrier frequency in
factory. Generally, there is no need for users to modify the parameters. In case of above the default
carrier frequency, users should derate 10% for each additional 1k carrier frequency.
