Goodrive3000 series medium voltage inverters
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 inverter to run in reverse direction. It is suitable in special cases
forbidding reverse running.

setting
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 inverter
increase, so the output ability of the inverter is affected. Under the high carrier frequency, the inverter is
used by derating. Simultaneously, the leakage current increase of the inverter 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.

autotuning
Select the mode of motor parameter autotuning.
0: No operation
1: Rotation autotuning: comprehensive motor parameter autotuning, the method is recommended when
high control precision is needed.
2: Static autotunnig 1: the method is suitable in the cases where the motor cannot decouple from load,
autotune the motor parameters totally.
3: Static autotuning 2: the method is suitable in the cases where the motor cannot decouple from load,
only autotune the previous 3 parameters.
Remark: ① Recommend rotation autotuning;
② For 4-quadrant inverter, recommend not operating the rectifier during parameter autotuning, otherwise
affect the accuracy;
