I built a 20hp rotary Phase converter for my Fanuc Robodrill.
Its balanced pretty good at about 245-249v between the lines (measured with my cheap multimeter). The incoming house line reads 245v.
When I turn on the Robodrill, the screen goes crazy and flashes like it's in an electrical storm or something.
I'm trying to figure out what's wrong.
Is there something wrong with the rpc? Is the line voltage too high (the transformer in the Robodrill has inputs for 200v, 220v, and 230v).,
or might the incoming wiring be wrong?
I really need some help with this problem. Thanks.
