Can't find that info anywhere, but if you say what the current colour coding is we might be able to help...

Thanks, the motors are Warner Electric Brake and Clutch - SM072-0060-KN and have eight wires:-
White & Brown; White & Orange; White & Yellow; White & Red; Brown; Orange; Yellow; Red.

I am installing ArcEuro Trade stepper drivers into my Emco 5PC.


Hopefully

Easy,
Brown, orange, yellow and red are the ends of the 4 coils, the white and colour are the opposite ends.
If you are wiring in parallel join red and brown for 1 connection.
White/red and white brown for term 2
Orange and yellow for term 3
White/orange and white/yellow for term 4

I assumed that connection 1 is +A, 2 is -A, 3 is +B and 4 is -B and wired my Z-axis driver accordingly. I am not able to jog the axis and it is possible to turn the Z-axis stepper against some small resistance when it is powered. Any thoughts or suggestions?
