Cause : Mode designation error comes when parameter setting was attempted in the External or NET operation mode while Pr.77 = "1". Parameter write was attempted when the command source is not at the operation panel (FR-DU08).
- Check that operation mode is PU operation mode.
- Check that the Pr.551 setting is correct.
- After setting the operation mode to the "PU operation mode", make parameter setting.
- When Pr.77 = "2", parameter write is enabled regardless of the operation mode.
- Set Pr.551 = "2"
