Can I run a Delta VFD-B (VFD022B23B) on single phase 220V input to power a 3Hp inverter spindle motor?
The spec sheets and manuals are confusing, some indicating that the 22 Kw units can run on single phase some showing only certain models can do so.
Also, I have been advised to replace the 22 Kw with a 37 Kw (VFD037B) to run the 3 Hp motor. The spec sheets from Delta indicate the 37 Kw (5 hp) will only run on 3 phase input. Is this necessary?
Thank you,
Mike
