Unless you are really experienced in fixing this kind of gear, it could just keep on having (expensive) problems. They just keep getting flakier as they get older. Some people are using my Pico Systems gear to run some older Hardinge HNC machines. > Anyone know the possibilty of switching one of these over to single phase > during the conversion?

So, for a 5 Hp motor, you'd get a 7.5 or 10 Hp VFD. I'm doing this in my shop on a mill and lathe. (There are a few VFDs that will detect the lost phase and won't run.) Also, the servo drives may be taking 3 phase power, this possibly could be a bigger problem to run on single phase.
