A friend just got a CHNC-I and we are planning a retrofit. The servo amps and axis motors have already been replaced by prior owner. It still has the original spindle motor (A06B-1006-B220#2000) and the original Fanuc spindle drive (A06B-6044-H008). He only has 240 V single-phase power. We do not know the condition of any parts. Is there any possibility of running the Fanuc spindle drive on single phase? If not, are there ordinary VFDs that can run the spindle motor? (I'm guessing, mostly from appearance, that it is a permanent magnet brushless motor, right?)
I think we have the rest of the retrofit fairly well understood, but just need some suggestions on the spindle drive.
Thanks,
Jon
