Cause : Lower limit fault detection comes when the inverter output is shut off when the load falls below the lower limit fault detection range. This protective function is not available in the initial setting of Pr.1491 (Pr.1491 = "9999").
- Check if the equipment load is too light.
- Check that the load characteristics settings are correct.
- Inspect the equipment.
- Set the load characteristics (Pr.1481 to Pr.1487) correctly.
