Cause : Fan alarm comes when the inverter that contains a cooling fan, FN appears on the operation panel when the cooling fan stops due to a fault, low rotation speed or different operation from the setting of Pr.244 Cooling fan operation selection.
- Check the cooling fan for a failure.
- The fan may be faulty.
