EEPROM Memory DWEZ Data Error

There is an error in the EEPROM peripheral circuit.

  • Re-energize the drive.

  • If the fault stays, replace the control board or the drive. For information about replacing the control board, contact Yaskawa or your nearest sales representative.

There is a problem with the EEPROM data.

Set A1-03 = 2220, 3330 [Initialize Parameters = 2-Wire Initialization, 3-Wire Initialization] to initialize the drive, then upload the DriveWorksEZ project to the drive again.
Note:

  • The drive detects this error if there is an error in the DriveWorksEZ program that was saved to EEPROM.

  • Do a Fault Reset to clear the fault.
