Mode Designation Error

What does Mode designation error mean?

Parameter setting has been attempted in External or NET operation mode when Pr. 77 Parameter write selection is not '2', or when the command source is not the operation panel. This error prevents parameter changes under specific operating mode constraints, aiming to maintain system stability and prevent unintended modifications.

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' to designate the PU as the command source.
