Cause : Control memory error comes when an error of the internal memory of the control electronics has been detected.

"EEF1" fault in Schneider Electric ATV610 drive indicates a Control EEPROM Fault. This means the drive is having trouble reading or writing data to its Control EEPROM.

  1. Verify the environment (electromagnetic compatibility).
  2. Turn off the device and then turn on again.
  3. Return to factory settings.
