Hello All,
I've been wracking my brain trying to find a definitave answer to this question, and while I can find discussions all over about stepper windings, phases, and technical information beyond my use, Getting This:

(summing up page 7's details
B to pin 6
/B to pin 7
A to pin 8
/A to pin 9

(I know that I'm losing efficiency by using a over powered motor for this drive, it's what I had on hand, thoughts on that too? running ~48v to this setup, and sofar so good, I think)

just hasn't been straight forward, and after hooking up my first guess of 4 leads to the db9, I've got no holding torque
Wondering if I need to join some of the wires pre db9?

Any help, insight, or an outright answers would be Awesome!!!

How is it wired now? If you have it bipolar parallel switching to series should gain some holding torque at the expense of torque at speed.

After I failed to get holding torque, I de-soldered the db9, and now am back to nothing wired. For this custom install, Yes, Speed has higher priority over Torque.

Bipolar parallel is probably the best way to wire it.

You will have to run no more than 3.5 amps through the motor, which means that you will give up almost half of the potential torque, but your torque should not drop off as much at higher speeds.

See figure 11 of Support for a wiring diagram.
