I've recently acquired an RP06 as part of a

to run it (why not?) I remember reading on this list a while back, that
it could be operated on single-phase power instead of three-phase.
Not likely.
I got a printset along with the drive, and it's
pretty unclear about
what would use the three-phase- it's almost like the third phase is
ignored, the 208v between the first two phases is fed to the
transformer, and the primary is sort-of center tapped to feed the 115
volt fans. Is this right? How would I go about feeding it
single-phase if that isn't right?
Sounds like you're looking for the printset for the electronics.
The drive uses a three-phase motor. Some people have suggested using
a capacitor-start arrangement to run it without three-phase, but I'm
very skeptical that it would work well.
