Mode designation error

What does Er4 mean?

This error occurs if parameter setting was attempted in External or NET operation mode while Pr.77 (Parameter write selection) is '1', or if parameter write was attempted when the command source is not the operation panel. It indicates a conflict between the current operating mode or command source and the attempt to write parameters.

• Invalid mode selection or transition attempted.
• Configuration error in mode selection parameters (e.g., P1-02).
• Attempting an unsupported operation for the current drive mode.

Click steps to track your progress.

1. 1

   Switch the operation mode to 'PU operation mode' before attempting to make parameter settings.

2. 2

   If parameter write is desired regardless of operation mode, set Pr.77 to '2'.

3. 3

   If writing from the PU, ensure Pr.551 (PU mode operation command source selection) is set to '4'.
