EEPROM error

What does 25, 94 mean?

An error occurred with the EEPROM (Electrically Erasable Programmable Read-Only Memory) of the MOVIMOT drive. This memory is crucial for storing configuration data, parameters, and operational settings.

• Data corruption in the EEPROM
• Hardware fault of the EEPROM component
• Issue during parameter saving or loading

Click steps to track your progress.

1. 1

   Measure the incoming supply voltage at the MOVIMOT drive input terminals and verify it is within the specified tolerance.

2. 2

   Check the current drive parameters using appropriate diagnostic software (e.g., MOVITOOLS) and compare them with the machine's configuration backup. If parameters are corrupted or unreadable, attempt to reload a known good parameter set.

3. 3

   Inspect all communication bus connections (e.g., AS-Interface, PROFINET, PROFIBUS) to the MOVIMOT drive for loose wiring, poor contacts, or electromagnetic interference.

4. 4

   Verify the firmware version of the MOVIMOT drive and consult SEW Eurodrive documentation for any known issues or recommended updates related to EEPROM errors for that specific firmware.

5. 5

   Perform a controlled power cycle of the MOVIMOT drive, observing if the EEPROM error clears or persists upon restart.
