Check the connections from the drive to the motor.
If an output contactor is being used, parameterize [Output Phase Loss] (OPL) = [Output cut] (OAC)
Test on a low power motor or without a motor. In factory settings mode, motor phase loss detection is active [Output Phase Loss] (OPL) = [Yes] (YES). To check the drive in a test or maintenance environment, without having to use a motor with the same rating as the drive (in particular for high power drives), deactivate motor phase loss detection [Output Phase
Loss] (OPL) = [No] (nO)
Check and optimize the following parameters: [IR compensation] (UFr), [Rated motor volt.] (UnS) and [Rated mot. current] (nCr) and perform [Auto-tuning] (tUn)

Make sure that the drive is connected to the motor in the event that a run command is given to the drive.
