EEPROM checksum fault

¿Qué significa 22 ?

A parameter save fault has occurred, indicating an issue with storing data to or retrieving data from the EEPROM. This can be due to faulty operation or a component failure within the EEPROM memory.

• Corruption of data stored in the EEPROM parameter memory.
• Failure of the EEPROM memory chip itself.
• Interruption during parameter writing or saving process.
• Electromagnetic interference corrupting EEPROM data.
• Aging or wear of the EEPROM memory.

1. 1

   Perform a full parameter reset to factory defaults (e.g., set P1-01 to 2).

2. 2

   After reset, re-enter critical parameters manually and save.

3. 3

   If the fault persists, attempt to read EEPROM content if a diagnostic tool allows.

4. 4

   Ensure stable power supply during parameter modification and saving.

5. 5

   Replace the device if the fault consistently reappears after parameter reset and re-entry.
