SANYO DENKI PMM-BA-5641-7 manual wanted

I picked up a Yuasa 4th access with a pcnc 500 controller. I have scoured the internet for a manual but none of them seem to match up. 

If anyone has info on how to communicate with this drive, greatly appreciated. I intend to gut the controller case and make it into a dumb box driven by my 7i77

thanks in advance. 

here are the manuals I found

I am planning  the exact same install for a 4th axis on a Bridgeport VX2T that I am re-controlling. 
Did you find or test to find the signals for the servo amp?  Any help would be appreciated.
