Cause : Power stage recognition- Multi module voltage or current rating mismatch comes when there is a voltage rating or current rating mismatch in a multi-module drive system. This trip is only applicable to modular drives that are connected in parallel.

1. A mixture of power modules with different voltage or current ratings within the same multi-module drive system is not allowed and will cause a Rating Mismatch trip.

2. Ensure that all modules in a multi-modular drive system are of the same frame size and rating (voltage and current).
