We have some problems with communication to drives (Mitsubishi) using UCM (universal communication ports) mfr. SquareD. Already revise all connections, and the inverter, also UCM configuration.
Can you give us some advises to make possible this communication?

Best Regards

 

I believe that if it is a UCM module, it was manufactured by a company called Niobrara (www.niobrara.com). They are an excellent company as far as tech support is concerned and if you contact them, they should be able to answer your questions.
