If load lost protection function is valid, when output current of the inverter falls below
detection level (P9-64) for longer than time set in
F9-65, the inverter responds load lost protection to act automatically (protection action is
determined by P9-49, factory default is free stop). Once load recovers during protection,
the inverter recover to frequency reference.
