    Silly question but you have checked the spindle isn't seized or the cable damaged.? It's often the silly things that bite you.!
    The cable is brand new but I'll check it just in case, the spindle is also brand new could the vfd be at fault? With the old spindle as soon as I pressed run it blew fuses in the 13amp plug the machine is on. The VFD powered on fine with the spindle unplugged counted up to 400 so I assumed the spindle failed

    It worked fine but I left it for 6 months other stuff came up and when I came back this started

    I only have 1, 2 & 3 pins soldered on as the spindle isn't earthed I was going to do that after I get it working I have checked continuity from the spindle plug to the VFD it seems good no shorts I have grounded the RF wiring

    The VFD to spindle cable length is ~5m one solid piece
