The drive can incorrectly start output phase loss detection in these conditions:
The motor rated current is very small compared to the drive rating.
The drive is operating a PM motor with a small load.

The output turns off and the motor coasts to stop.
If the drive loses more than one output phase, it will trigger LF [Output Phase Loss].
