Retiredhh,

I can tell you about the Vexta wire color codes as they are what I have.

Black--------|A+
|
|
Yellow-------|Center Tap
|
|
Green--------|A-


Red----------|B+
|
|
White--------|Center Tap
|
|
Blue---------|B-

I hooked the power up to the White and Yellow. The phases were Black, Green, Red and Blue in that order. Of course that was for my unipolar driver. I guess you eliminate the two center taps for bipolar use.

PS The ascii graphics didn't come out very well. I do have the origional spec sheet. It doesn't give much more valuable info than that though. If you want I can scan it for you. Let me know.
