This report describes a logic scheme which forms the basis for the design of a positioning system for digital control of mechanical motions. In order to ensure a desired position denoted reference R, the system is so arranged that the mechanical parameter always approaches R from an off-set reference R-6R with a suitable low speed. This provides the possibility of avoiding the effect of a dead zone in the mechanical transmission, and the stored mechanical energy may be released daring the low-speed motion.
