Introducing EVOLUTE™ series encoders Resolutions down to 50 nm Compatible with BiSS® serial protocols Maximum linear speed of up to 100 m/s Built-in position checking algorithm for inherent safety Please read the notes below: Based on Renishaw’s industry-proven absolute technology, EVOLUTE is a true absolute non-contact optical encoder with a 50 µm scale period, bringing superb installation tolerances and greater dirt immunity for applications that demand not only the highest operational integrity, but where fast installation is critical. Resolutions down to 50 nm along with low SDE and jitter from cutting edge optical design and high speed digital signal processing (DSP) give EVOLUTE that targeted performance to meet the needs of the most demanding OEM applications. 11/11/2018

Improved dirt immunity Renishaw plc 11/11/2018 Value to you Good metrology Improved dirt immunity Faster installation Value Please read the notes below: Good metrology: EVOLUTE offers good metrology performance, providing smooth velocity control and high positional stability Faster installation: In OEM applications, machine build time is critical, as time saved in component installation allows shorter manufacturing lead times and ultimately higher profitability. One of EVOLUTE’s main value propositions High speed: with a top speed of 100 m/s. Faster processing and throughput for the customer Robust operation: To end-users of production machinery, maximising up-time is a top priority. EVOLUTE’s robust design helps to maximise process efficiency Improved dirt immunity: Several mechanisms enable high dirt immunity including: state-of-the-art DSP to overcome light scattering effects of oily or greasy smears, a custom point LED and a redundancy in the absolute code pattern, meaning that EVOLUTE can still function if the scale is partially obscured by contamination Robust operation High speed 11/11/2018 Confidential

EVOLUTE basic principles Readhead sensor is analogous to a digital camera Image of scale is taken by readhead Raw data extracted from image and processed Error checking algorithm extrapolates the next reading and compares with actual for enhanced safety Please read the notes below: Readhead sensor is analogous to a digital camera. Image of scale is taken by the readhead on receipt of a position request pulse. Raw data is extracted from the image. Digital signal processing is performed and fine position is determined by interpolation. Digital absolute position code is produced which is subsequently interpreted by reference to a look-up table (shown). Position information is determined by separate ‘error checking’ algorithms that eliminate the risk of common cause failure. ** Slide animates the scale and output waveform together – the presenter should allow several seconds for this to run** 11/11/2018
