Mode Designation Error

What does Mode designation error mean?

Parameter setting was attempted in External or NET operation mode when Pr. 77 (Parameter write selection) was not '2', or parameter writing was attempted when the command source was not the operation panel. This prevents modification of parameters under specific operating conditions to maintain system integrity and prevent unintended changes.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   If the parameter unit (FR-PU04/FR-PU07) is disconnected, set Pr. 551 (PU mode operation command source selection) to '9999' (initial setting).

2. 4

   Alternatively, set Pr. 551 (PU mode operation command source selection) to '4' if using the PU as the command source.
