Hi

Hope someone can held me with my limited electrical experience. I’m currently building a CNC router and have most of the parts. Started to build the electrics up and have got the 4 stepper motors working using Mach3 usb BOB. Then I got the 2.2 kw spindle working direct to the VFD. I have set up the twin relays for spindle rotation working. The problem I have is connecting the wires from the BOB to the VFD as the VFD terminals are not named VI, ACM or VR so unsure which terminal connects to the BOB. I have a 24 volt supply to the BOB along with USB feed just didn’t want to damage either the VFD or the BOB by connecting incorrectly.

Thanks

Mark!
