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.
- Check the Pr.77 Parameter write selection setting.
- Check the settings of Pr.31 to Pr.36 (frequency jump). (
- Check the settings of Pr.100 to Pr.109 (adjustable 5 points V/F).
- Check the connection of PU and the inverter.
- Check the Pr.72 PWM frequency selection setting.
