Thank you Keneth.

Here is the response from shopbot support (this wasn't in my installation manual) and every thing worked ok:

onnect the VFD and Spindle

Connect the brown VFD cable to the Control Box.

The brown cable may have one of two possible wire combinations. One combination has three wires black, white, and red (red clipped back). The second combination has three wires black, green, and red (red clipped back). The white and green are interchangeable.


* Make sure the VFD is OFF before proceeding.

* The VFD has been pre-wired with the brown cable at the factory.

* Run the brown cable from the VFD to the Control Box.

* Pass the brown cable from the VFD through the cable access in the right side of the Control Box.

* Connect the black wire and the white (or green) wire from the brown cable into the VFD terminals on the Control Board labeled "SPINDLE1" (For a second spindle, use the terminals labeled "SPINDLE2"). For Spindle #1 connect the black wire to the "F1" terminal and the white (or green) wire to the "C1" terminal, and for a second spindle use connections "F2" and "C2" in the Spindle2 section. The red wire is not used and should be clipped back.
