Dear Viesturs, Thanks for your reply. I m sure that these linear scales from Heidenhain in combination with a Heidenhain controller have a analog output. I also know that some of the Maho mills (from few year later) have a Philips 432 controller. Maybe the glass scales in combination with these controller are quadrture !!!! I will look for documantation but I m not sure i can help you . I have only a general service manual for the Maho mh 700c Regards j^p
