Cause : Control Circuit Error (EEPROM memory Data Error) comes when the drive power supply was de-energized while a communication option entered a parameter Write command. An EEPROM peripheral circuit error occurred.

1. Set A1-03 = 2220, 3330 [Initialize Parameters = 2-Wire Initialization, 3-Wire Initialization] and initialize the drive.
2. Re-energize the drive.
3. If the fault stays, replace the control board or the drive.
