Parameter storage device fault (main circuit board)

What does E.PE2 mean?

This fault indicates a problem with the non-volatile memory on the main circuit board of the FR-A800/A800 Plus Series drive, where parameters related to the main power circuit are stored. This can lead to persistent issues with the drive's power stage operation.

• Corruption of parameter data on the main circuit board's memory due to electrical transients or noise.
• Internal hardware fault of the main circuit board's memory component.
• Unstable power supply or grounding issues affecting the main circuit board.
• Firmware issues specific to the main circuit board's data storage.

Click steps to track your progress.

1. 1

   Attempt to re-initialize the drive's parameters to default settings and then re-enter all necessary application-specific parameters, paying attention to main circuit-related settings.

2. 2

   Verify the stability of the main power supply and ensure proper grounding of the FR-A800/A800 Plus Series drive.

3. 3

   Check the fault history for any preceding main circuit faults (e.g., overvoltage, undervoltage) that could have triggered this memory fault.

4. 4

   Inspect the main circuit board for any visible damage, signs of overheating, or component stress.

5. 5

   If the fault persists after re-parameterization and power cycling, it likely indicates a hardware failure of the main circuit board, requiring replacement of the drive.
