Help with VFD connections

Hi Everyone,

Getting ready to put together my new Asteroid but I'm a bit confused with connections. The setup manual showed two possible configurations but not for the equipment that I have and I don't want to hook up the wrong wires.

This is the VFD that I received Simphoenix and the wire harness that has a red wire (24v), white wire (AI) and a black wire with 3 possible connection points. Any advice on where to connect the black wire?

Thanks
Ken

Ok. So I figured out the connections because the correct page was not included in the start up manual.

My only question now is about the twisted pair of black wires that was to be connected to the unity controller, but since I have a spindle, it says that this connection isn't needed. Does that mean it won't be used at all? Just want to be sure I don't screw something up.
Thanks.
Ken

I personally don't use a VFD, but you might check out this page on their wiki: http://www.probotix.com/wiki/index.php/VFD_Spindles
