Hi all,

I am working in commissioning a spindle I have acquired for a home build CNC machine and am having some trouble getting it to run correctly.

I have already checked the motor, all coils have equal resistance, no shorts to ground and wired to terminal block in motor correctly.

The vfd parameters I have set are; nameplate frequency, voltage, speed, max current, ramp time and command source (to run from keypad, the 2 pins with a switch require a 'run' signal)

On attempting to run the motor, it turns slightly to one position then holds and won't move.

I have set up 50hz motors on VFD's before and am familiar with the spindle/VFD setup on the CNC table at work and I am not sure what is going on! Any help would be greatly appreciated! Attached are a couple of pictures of what I am working with.
