Cause: Initialization Required comes when the drive, control board, or terminal board has been replaced and the parameter settings between the control board and the terminal board no longer match.

ope04 yaskawa indicates initialization required operator error. This means the control board settings and the power module hardware do not match. The drive detects that the installed hardware is different from what the control system expects.

Follow these steps to correct

• To load the parameter settings to the drive that are stored in the terminal board, set A1-03 to 5550.
• Initialize parameters after drive replacement by setting A1-03 to 1110 or 2220.
• After this restart the drive.
