I'm working with Pere/Petter Reinholdtsen on converting his Mazak 15/40. It looks like a great machine, capable and compact, but we've run in to a bit of an issue.
The machine has servos with resolvers, but the resolvers only connect to the servo amps, not to the controller. The are connectors on the amps for passing the resolvers on to the controller, but those cables are not present. Instead this machine has the fairly rare optional Magnescale option, so each axis has magnetic linear scales (Sony SR-721RM scale with MSD-9037 detector). These are connected directly to the controller, and the old controller used them for position feedback. These are circa 1987 or so. Does anyone know how to interface these position sensors to LinuxCNC? Another option might be to ignore the scales and access the resolvers by connecting to the currently unused resolver outputs on the servo amps. I'm guessing in this case the servo amps provide the resolver excitation signal and we'd try to passively read the resolver response.
