Its a strange one indeed, should be a piece of cake to set that up. The pdf shows the commutation is exactly what AB wants or at least as far as I can see it does, same phases same halls for those phases.
Only thing I can think of is the wires are not corresponding to the pdf but find that hard to believe, if it was a cheap Chinese motor then yes I could believe it but not with a Sany.
BTW I found the code I used to make my first diff board, similar to pics, not sure if its any use to you as its metric
but also made to fit directly into a PMDX 122, suppose you could just fit connectors instead of the heavy copper wire.
