EEPROM Memory Data Error

Was bedeutet CPF06 ?

An error detected in the drive's EEPROM (Electrically Erasable Programmable Read-Only Memory), where parameters and operational data are stored. This can indicate data corruption or a faulty memory chip, potentially causing the drive to operate with incorrect settings or fail to store new ones.

• Corruption of data in the EEPROM due to power fluctuations or severe electrical noise
• Faulty EEPROM chip on the control board reaching end-of-life or experiencing failure
• Firmware update interruption or failure causing inconsistent data storage.

1. 1

   Perform a parameter initialization (e.g., using parameter A1-03 for a factory reset) and re-enter all parameters manually.

2. 2

   Cycle power to the drive to attempt a memory refresh and clear any transient memory errors.

3. 3

   If the fault persists after re-entering parameters, the control board containing the EEPROM may need replacement.
