Goodrive3000 series medium voltage VFD
0: Run at the default direction. The VFD runs in the forward direction. FWD/REV LED is off.
1: Run at the opposite direction. The VFD runs in the 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: When the parameter is restored to the default value, the motor's running direction is restored to the default
one. Exercise caution before using this function if the change of motor rotation direction is disallowed after
commissioning.
2: Disable reverse running. It can be used in some special scenarios where reverse running is disallowed.
Function
code
P00.14
Advantage of high carrier frequency: ideal current waveform, little current harmonic wave and motor noise.
Disadvantage of high carrier frequency: increasing the switch loss, increasing VFD temperature and the impact to the
output capacity. The VFD needs to derate on high carrier frequency. At the same time, the leakage and electrical magnetic
interference will increase.
On the contrary, an extremely-low carrier frequency may cause unstable operation at low frequency, decrease the torque,
or even lead to oscillation.
The carrier frequency has been properly set in the factory before the VFD is delivered. In general, you do not need to
modify it.
When the frequency used exceeds the default carrier frequency, the VFD needs to derate by 10% for each increase of 1k
carrier frequency.

The function code is used to select a motor parameter autotuning mode.
0: No operation
1: Rotary autotuning.
Comprehensive motor parameter autotuning. It is recommended to use rotating autotuning when high control accuracy is
needed.
2: Static autotuning 1
Comprehensive motor parameter autoning. It is applicable in scenarios where the motor cannot be disconnected from
load.
