However—and this is critical—. The alarm logic is a symptom, not a diagnosis. The source of the overvoltage can be electrical (mains supply), mechanical (regenerative energy), or internal (component failure).

If your facility relies heavily on these machines, consider scheduling preventive component level rebuilds (replacing electrolytic capacitors) for modules that have been in continuous service for over a decade. To help narrow down the diagnosis, let me know:

) of the current controller is set too high, the loop becomes unstable, oscillates, and hits its limit.
