Yes that's right. There's DC voltage monitoring now, but the only use of it at the moment would be to verify precharge. But I'm not even doing that right this second.

I have NOT added the V/Hz to this code yet. It's a good idea though. It's pretty easy to get working. IT was version 0.001 a few years ago. I just need a lookup table, and to race through the table at a given frequency, with all 3 phases 120deg apart from each other.
