    Awesome!!!! Thanks so much! So many people I have talked to have been insistent that the spindle and control board need to be on separate circuits… I didn’t give that a second thought.

    I’ll post...
  3. Re: EMI noise, grounding, connection problems with new VFD 2.2kw spindle

    Yes... 240 v (measures at 239ish)

    How can I troubleshoot the grounding loop? I can't figure out where it would be creating a loop? Currently, the control board is plugged into a 120v line and...
  4. Re: EMI noise, grounding, connection problems with new VFD 2.2kw spindle

    I would love to find out what is actually going on. I don't know if photos will explain very much, but I will try to explain how it is setup and wired.

    Here is what I have:

    No error, no syntax. The spindle stays on but the cnc stops in its tracks. The indicator in my program (Easel) that shows connection, shows as not connected.
  7. Re: EMI noise, grounding, connection problems with new VFD 2.2kw spindle

    Thank you. Forgive me for asking, and please understand that this is a real question, but how could it be the USB cable? It stays connected as long as the steppers and wire grounds are disconnected...
  8. Re: EMI noise, grounding, connection problems with new VFD 2.2kw spindle

    Thanks for the reply. I did test the spindle before installing it and it tested normally. Also, it is my understanding that all motors produce a certain amount of EMI, but these spindles in...
  9. EMI noise, grounding, connection problems with new VFD 2.2kw spindle

    I am at a loss and don't know enough about EMI and/or grounding loops to troubleshoot my issue properly, and I am hoping someone has something I haven't tried.

    Re: VFD troubleshooting

    Well my replacement motor came today, and after seeing how this one was packed, I am thinking that the kit I got before had been opened and damaged.

    Re: VFD troubleshooting

    Ok... so it looks like a winding is bad.

    P1 - P2 = 1.2 ohm
    P2 - P3 = .5 om
    P1 - P3 = 1.1 ohm
    No continuity with P4

    I did check the wiring in the plug and there didn't seem to be an issue,...

    Re: VFD troubleshooting

    Mactec54 thanks for the input.

    My motor is water cooled, with 4 pins.

    I have another motor on order, the one I have clearly is damaged. I'll adjust the PD73 and PD11 to 120.

    I appreciate...
