I also have 3 more I have tested SURELY one of them would be still good (;-). They go through all the motions.

I don't have an AB servo to test with.

I think I am just missing the secret handshake. OR it may be time to pack it all up and call the scrap man.  (;-)

HIYA HOOD question for you. What line drivers are you using for the step and direction on the AB drives?

On the big  lathe I use the acustep BOB that CNC Building blocks used to make, it has diff out. On the Beaver Mill and Bridgeport mill I made up my own boards  with SN75172 quad drivers and on the wee lathe I use the CSMIO/IP-S controller which has differential outs.

Hi Terry,
  Here is what Hood helped me to set up for mine. :)

WOuld you happen to have a schematic of that setup. I can solder (;-)

Note on the drive/motor  does not look good. IF I could figure out the crossover between the two systems it would work BUT there seems to be about a 1000 combinations to try to make it work.

So far after 3days of combinations it still does not match up.

I was hoping to find someone that could take the Phase/Hall sequence that AB wants and look at the Phase/Hall sequence that the SDenki does and figure out the conversion.

I have drawn them out in cad and tried what I thought to be the good combo and all the variants of that without luck.

Several Servo techs have offered their good lucks (;-)  IF AB were cooperative they could probably look at the specs and get it right BUT IF a frog had wings he would not bump his rear when he jumped.

BUT to be fair the AB drive does have the tools to do it.   BUT it is like having an atomic bomb and NO plutonium.

Using a scope to verify the phasing, like Hood suggested is the best way.

I have the sequence graphs of the motor AND the drive BUT the combos I come up with do not work.
