Title: (EN) Method and device for the cyclic digital transmission of a position value of a moving object with inertial mass
Abstract: front page image
(EN)

In a method and device for the cyclic digital transmission of a position value of a moving object with inertial mass, the value range of the transmitted position value is restricted such that no complete rotation or, in the case of a linear motion, other complete period caused by mechanical conditions may be mapped, and the actual position is formed by detecting value-range exceedances in an evaluation unit.
