Cause : Terminal Board Mismatch Error comes when the drive, control board, or terminal board have been replaced and the parameter settings between the control board and the terminal board no longer match.

  1. Set A1-03 to 5550 to load the parameter settings stored in the terminal board to the drive.
  2. Initialize parameters after drive replacement by setting A1-03 to 2220 or 3330.
