YES
The base frequency or the rated
rotational speed of the motor is
not set correctly. Check their
settings.
Enter the correct value for 

* When using a long cable (guide: 30m or over), be sure to make auto-tuning 1 (=).
YES
*2: No problem even if the motor is not connected.
*3: It does not matter whether the motor is under load or no-load
conditions.
*4: As for models 200V-55kW or more and 400V-90kW or more,
NO
Is the motor actually
connected and in a
standby state?
YES
Check the precautions to be taken whe
