Yaskawa · E7 Drive
An Operator Programming Error occurs when the Drive's kVA setting is incorrect, usually after a control board replacement. The Drive will not operate until this parameter is corrected.
Click steps to track your progress.
1. Consult the drive's hardware manual to locate the kVA selection method (e.g., dip switches, jumpers, or parameter A1-02) on the control board.
2. Verify the physical kVA selection (switches/jumpers) on the control board matches the drive's nameplate kVA rating. Adjust as needed.
3. If kVA is set via parameter (e.g., A1-02), ensure it is programmed to the correct value corresponding to the drive's power section rating.
4. Power cycle the drive (turn off for 30 seconds, then on) after making any kVA selection corrections to allow the new setting to take effect.
5. If issue persists, check the firmware version of the control board and ensure it is compatible with the power section of the drive.
