Jon and Dave, That seems to be a nice small motor/ drive combo. I have 4 of them. I have one of the drive/motors running on a Motenc lite board. Other work pulled me away from it. I need to get back to it and tune the drive. Dale

So, that was quite easy to decipher and design a simple gizmo to convert back to the standard UVW commutation signals. These motors have traditional ABZ position encoders. On the proprietary Yaskawa motors made for their own drives, the encoder only has 3 channels, and encodes position AND commutation all in those. A and B are normal, but the C channel flips the phase relationship between it and the other two to give commutation and index pulse encoding. I got the general idea, but I can't say I understand how it works.
