Abstract
A method for finding a reference correction value of an angular encoder index mark is given. The angular encoder has a first read head, a second read head, and a patterned element that includes incremental marks and an index mark. In a first instance, the first read head detects the presence of the index mark and, in response, the second read head generates a first analog signal. In a second instance, the first read head detects the presence of the index mark and, in response, the second read head generates a second analog signal. A processor determines the reference correction value based at least in part on the first analog signal and the second analog signal.
