Abstract

In incremental detectors, measurement signals thereof are first corrected in graduation-specific fashion with respect to amplitude offsets, and phase displacement, and a rough angle is determined. The residual error of the rough angle is fine-corrected via rough-angle-specific, graduation-independent rough angle correction values and a position signal is determined in this way. The correction values for amplitudes offsets, and phase displacement are determined using regression, and the rough angle correction values are determined using high-precision reference angle measurements.
