    770 spindle running in reverse

    I have a quick question for the 770 owners. I disconnected the spindle motor a few month ago and today, first time using it since, I realized the spindle is turning in reverse. Can anyone snap a picture of the wiring on the spindle (inside the the little electrical box) Or if you can just tell me which go where (they are numbered) I could not find it in the user manual. Thanks in advance!

    Doesn't that have a standard 3 ph induction motor? if so just swap any two leads to the motor, or out of the VFD.

    Christian,

    Here is a picture I took before mounting the power draw bar on my 770.

    Thank you Kevin! Thank you to all of you actually, swapping two wires did it. Luckily my mistake cost me only a 56 drill bit!
