CRadek probably knows how this is setup - he did a Mori Seiki Junior - 
you might want to ask him on the IRC.

My guess is that the switches are setup in a full quadrature fashion so 
it can determine which way the magazine is rotating and sense the 
movement in 1/4 pot movements..  (At least that is what I would do ;-)  )

If the switches are out phase by 90 degrees (360 degrees being on 
movement between pots) , that is probably what they are doing.  That way 
they can sense direction and movement by looking for the edges of the 
switches.

The Z signal resets the count.   I could be entirely wrong though - I'd 
track down Chris.

Tracking rotation and movement in Classic Ladder with a full quadrature 
setup is pretty easy - if that is what is happening.  I could send you a 
ladder code snippet if that is the case.
