ROTARY ENCODER AND DEVICE AND CORRECTION METHOD FOR AUTOMATICALLY CALCULATING CORRECTION VALUES FOR THE ANGULAR MEASUREMENT VALUES OF A ROTARY ENCODER

摘要

The invention relates to a device (9) and a correction method for the automatic calculation of correction values (35) for angle measurement values (26) of a rotary encoder (1). In order to improve the measurement accuracy, the device (9) is designed to receive a value (34) of the magnetic flux density (B) measured by a magnetic sensor device (7) of the rotary encoder (1) in at least two spatial directions, at one Angular measurement value (26) to calculate at least one variable (29, 59) representing a relative position of the magnetic sensor device (7) to a material measure (5) of the rotary encoder (1) from the magnetic flux density (B) and from the at least one variable (29, 59) to calculate at least one correction value (35) for the angle measurement values (26).
