Parameter Storage Device Fault

What does Parameter storage device fault mean?

An abnormality has occurred in the component (control circuit board) where parameters are stored. This suggests a hardware issue with the inverter's non-volatile memory, potentially leading to incorrect operation, loss of critical settings, or failure to save new parameters. Frequent parameter writes for communication purposes can stress this component.

• Internal EEPROM (Electrically Erasable Programmable Read-Only Memory) or Flash memory corruption due to power transient.
• Degradation or failure of the non-volatile memory chip on the inverter's control board.
• EMI (Electromagnetic Interference) causing data corruption during parameter writes or reads.
• Manufacturing defect in the memory module or its associated control circuitry.

Click steps to track your progress.

1. 1

   Document all current parameter settings by manually recording them or using configuration software (e.g., FR-Configurator2).

2. 2

   Attempt to initialize all parameters to their factory default settings (e.g., Pr. 77 set to 1 or 2, then cycle power).

3. 3

   Re-enter all necessary parameters from the recorded list after initialization.

4. 4

   Perform a firmware update for the inverter to potentially overwrite corrupted memory sectors (if applicable).

5. 5

   If the fault persists, replacement of the inverter's control board is necessary as the memory device is typically integrated.
