Output phase loss

What does E.LF mean?

The inverter output is shut off if one of the three phases (U, V, W) on the output side (motor/load side) is lost. This typically indicates a broken wire, loose connection, or open circuit in the motor wiring, leading to unbalanced currents and potential motor overheating.
