RE: [CAD_CAM_EDM_DRO] Interfaceing Glass Heidenham Graticules to Rutex

I am intending to convert an old automatic PCB inspection machine to a CNC
router / engraver.

Having already made a large router using Rutex amps and running DeskCNC
(With great success!)

I am raring to go on this project.

The only thing that I am unsure, of and look to the group for help or info ?
Is to the possible interfacing of the Heidenham glass graticules.

The system as it stands has a graticule on each axis and a tachometer fitted
directly to each of the 3 servo's

The aged control logic (Motorola MASS BUS) seems to drive the servo amps
with a 0 to 10 Volt input.

I intend to scrap all the existing logic and fit Rutex amps.

Here's the question - How do I interface / is it possible, what appears to
be s sine wave output from the graticules to the Rutex amps ?

Any info would be most appreciated.

Rgds to all and Happy Holidays (more time to work on our projects !)
