Industrial Control Loops and How They Apply to Encoders

Download Whitepaper
There are a several ways to mitigate against sources of instability and error in the design of a precision motion stage. Control-loop architecture is an important consideration when assessing encoder performance in the context of overall machine design. 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.
