Initial setup on my CNC router build. I have a Huanyang GT series VFD powering my 2.2kw 220V spindle. The spindle "sputters" a half revolution on start up and that's it. It will not spin. I've triple checked VFD settings, factory reset, wiring checks and cannot get the motor to spin. Full transparency, I'm a complete novice on the VFD setup but I'm pretty confident on the wiring aspect. Any suggestions??
