I checked 3 induction sensors inside revolver. Two of these are used to define direction of revolves and third one are used to define lock position. Each of these sensors is ok. I suppose the maschine lost reference position of first tool. Could anybody give me more details in this topic? How can I reset or get back this parameter?
