Cause : Parameter write error comes when parameter setting was attempted while Pr.77 Parameter write selection is set to disable parameter write. Overlapping range has been set for the frequency jump.
Overlapping range has been set for the adjustable 5 points V/F. The PU and inverter cannot make normal communication. IPM parameter initialization was attempted while Pr.72 = "25".
- Check the Pr.77 Parameter write selection setting.
- Check the settings of Pr.31 to Pr.36 (frequency jump).
- Check the connection of PU and the inverter.
