SOURCE: IGBT FAULT ERROR KEEPS OCURING ON DF6 340 IVERTOR
E30 IGBT fault If an excessive current is applied at an IGBT (transistor in the power end stage), the output voltage
is switched off to protect the transistor.
Sounds like maybe a fan has gone bad and is drawing too much current.
Try disconnecting the fans and reconnecting one at a time. Also check
the fans to make sure they turn free and are not blocked.

most warning and alarm's are set less than what the manufacture rating is. it's a safety feature without it we would overload all our stuff
