I recently acquired a Sankyo Cartesian robot that was in fully working condition when it was pulled from production. The system is complete with a highly proprietary Sankyo SC3000 controller and touch screen pendant. The servos on the X and Y are Sankyo H27LK52 267W optical AC servos. The Z is a smaller 110W with electronic brake. I haven't been successful in finding anything to either control the servos or to post process for this controller. I have only a couple options at this point; Pull the servos and the controller and sell them; or sell the robot as a whole and build from scratch. I'd like to keep the servos as they are really beefy and obviously perfect for the machine but do me no good if I can't control them. I don't know what my other options are. Take a look at the photos and let me know what you think. Is it worth putting the money into the servos and controllers or keeping it whole and selling off.
Contacts I've tried already: Geckodrives, BobCAD as they had a post processor for Sankyo but not this machine; Sankyo with no response. Derek at Motomation.com
Looking at possibly replacing the motors with the 7.2Nm 3 axis kit from DMM-Tech.
Any help or advise would be greatly appreciated.
