A little update this morning after last night's experiments I built on that a bit this morning. I upped the MFD's on the B-C and A-C caps a little at a time till I got close to what I think I wanted in voltage. This is what I ended up with...
Phase ===========> A-B B-C A-C Caps 50MFD 100MFD 220MFd RFC on 246v 263v 271v Samson @440 RPM 246v 247v 249v 611 Drive on 245v 243v 241v Engraving @6k RPM 244v 243v 234v I grabbed a program at random an it turned out to be engraving my company logo at 6k RPM. Now mind you this was not 0 to 6k but 0 to 2k with a 0.09 second pause between 100 RPM increases up to 6k. To my surprise the program ran to the end without a fault including rapids at 295IPM on the Z axis. When I go to town I'm going to snatch up a few more caps to play with and bump up A-C a bit more to try and even it out. This will at least allow me to make parts for the time being until I either get an isolation transformer or generator. The interesting thing that I discovered is if I start up the Samson lathe with the 611 on I get a fault and have to reset the drive. This leads my tiny brain to think that it is a voltage drop to some degree that is tripping out the 611... what do you guys think? When my neighbor gets around to showing me how to store the traces in the scope I'll try and capture the wave form when this happens. Thanks for all the help and ideas.
