System and method for aligning a quadrature encoder and establishing a decoder processing speed

摘要

A system and method are disclosed for determining the minimum required processing speed for a quadrature decoder using measurements of an encoder performance, and to assess the safety factor of a particular decoder processing speed. The system and method may also be used to indicate proper adjustment direction by displaying real-time error measurements during encoder alignment. The system measures the logic state width error and provides for calculation of alignment parameters, processing speed and a safety factor. The method allows a measured the logic state width error can be used to for calculating a minimum required processing speed and a safety factor.
