Cause : Model error comes when a different model was used when parameter copy from the operation panel or parameter verification was performed.

1. The data in the operation panel were not correct when parameter copy from the operation panel or parameter verification was performed.
2. Check that the parameter copy or verification source inverter is of the same model.
3. Check that parameter copy to the operation panel was not interrupted by switching OFF the power or by disconnecting the operation panel.
4. Perform parameter copy and parameter verification between inverters of the same model .
5. Perform parameter copy to the operation panel from the inverter again.
