Dears,

I would like to ask for a fault occured on our drive Loher Dynavert 2j3d maybe due to a lightning.This drive is 3500 kw. It has 2 incommers and 2 outgoing. It is feeding a big fan motor.

The screen showing "Fault System 2. IC reactor UD". Is anybody can suggest any idea regarding this fault?

Thank you in advance.
