I see, I believe I tried a similar version made by CUI but it was in the early stages of development and I had varying degrees of success with it.
Those look similar, if so they are self calibrating, i.e. requires no scope to align.

Yes. Just align the rotor to the zero point and set the encoder with a button.
What I don't know is how to get the rotor to it's zero point. I came across a blog entry today. The poster says if you apply +5vdv to the U phase and - pole to the V phase then the rotor will move to the zero point. Sounded interesting to me.

Could you please explain the wiring and voltages? I'm confused if we apply DC voltage to the motor, and or encoder. Without a voltage on the motor windings, how do you find "zero" on the motor? Is it possible to do a slightly modified version of alignment with the motor ON the machine?
Does the same procedure apply to a Yaskawa AC servo w/8192 Inc encoder?
You rotate the BLDC motor in order that it will generate a AC wave form on the 3 phases.
Both the A phase and the corresponding commutation pulse is monitored on a scope and the encoder turned until the commutation is as is shown on the PDF.
IOW you check one phase at a time.
AFAIK the Yaskawa AC servo is just that AC so the BLDC version may not apply as far as alignment .
