Write error during operation

Was bedeutet Er2 ?

This error signifies that a parameter write was attempted while Pr.77 (Parameter write selection) was set to '0', which explicitly disables parameter write operations during inverter run-time. It prevents accidental or unauthorized parameter changes while the system is active.

• Data corruption during an attempt to write operational parameters.
• Interruption of power supply while parameter changes were being processed.
• Internal memory error during parameter write operation.

1. 1

   Stop the inverter operation before attempting to make any parameter settings.

2. 2

   Alternatively, set Pr.77 to '2' to enable parameter write capability during operation.
