Well I may have lucked out as I bought the SEM and drive off eBay. Have not confirmed that it is healthy. Cables were stubbed off so there is a lot of fussy work to reconstruct the cabling. Resistance checks seem to confirm that it is what the label claims.: an AC servo motor and Hauser drive. If anyone knows the cable color codes used by Hauser that would be a real boost.
Thanks for replying.
