摘要： The invention relates to the process and device for adjusting a rotary encoder, i.e. the absolute magnetic rotary encoder with Hall effect sensors which, when positioned in the form of a circle, detect the magnetic field of a diametrically polarised permanent magnet. The rotary encoder adjustment process features the following: the actuator magnet turns once or several times over the sensor circuit, whereby the time-dependant rotation angle is recorded/stored; time-dependant presupposed values of the rotation angle are calculated; these are then subtracted from the measured actual rotation angle values; by analysing the obtained difference, the electric parameter values for the sensor circuit are determined in such a manner as to make the newly measured difference based on new electric parameter values smaller than before the change; the electric parameter values for the sensor circuit are written into the sensor circuit.

摘要： A magnetic encoder apparatus is presented that includes a plurality of magnetic sensor elements (e.g. Hall sensors) for reading an associated magnetic scale that produces a periodically repeating magnetic pattern. The plurality of magnetic sensor elements produce a plurality of sensor signals and an analyzer is provided for analyzing the plurality of sensor signals to provide a measure of the position of the magnetic sensor elements relative to the associated magnetic scale. The analyzer is arranged to use the plurality of sensor signals to assess the period of the periodically repeating magnetic pattern sensed by the plurality of magnetic sensor elements. In this manner, the requirement to carefully match the period of the sensor elements with the periodically repeating magnetic pattern of the associated magnetic scale is avoided.
