Error E.LF

When I start the inverter from an external source, the motor rotates for several seconds, and then the "E.LF" error occurs. I checked wiring and found no problem. The motor seems fine because it rotates for several seconds.
What are the possible causes for this? What else should I check?

Answer

Measure the megger values on the inverter's output side.
If there is no problem:
If the motor capacity is extremely smaller than the inverter capacity (as a guide, the output current is 25% or less of the inverter rated current), this output phase loss can occur.
In this case, set Pr.251 (Disable output phase loss protection parameter) to "0" to disable the output phase loss protection.
