Drive Motor A Excitation Current Too High
This code is in our catalogue but has not yet been through editorial review, so the guidance below is limited to what our structured data supports. We publish deeper diagnostic content only after a code has been reviewed — here is why.
The drive motor A excitation current exceeds the calibrated maximum. Field excitation cannot be measured or controlled reliably.
A trouble code records what a control module measured. It does not identify which part failed. Test before replacing anything.
