Industrial control loops and how they apply to encoders

16 March 2017

Control-loop architecture is an important consideration when assessing encoder performance in the context of the overall machine design. There are a number of ways to mitigate against sources of instability and error in the design of a precision motion stage, for example. This article illustrates the potential of Renishaw's RESOLUTE™ absolute encoder system for applications that traditionally demand ultra-fine pitch incremental encoders with cyclic errors in the 1 nm range.
