I do not understand what is meant by 'the wild leg' here. If you mean two phases were at 239 V and one phase was at 199 V, I would be having kittens! That is a seriously UNbalanced supply and WILL cause significant problems. For that matter, it means the supply is way overloaded on one phase. NOT GOOD. If it means something else I am just confused.

If you Google wild leg or high leg Delta it will explain the setup, the neutral is not necessary on the feed to most CNC machines, just the 3 ph supply.
High leg delta is not used very much nowadays.

One thing is very clear to me already: your problems are coming in on the supply, imho.

I agree, this is why I think that monitoring where the trouble ends up, and that is at the 100v 200v control is probably the easiest.
