Renishaw will be exhibiting at Drives and Controls 2014 from 8–10 April in the National Exhibition Centre (NEC), Birmingham, UK. Visitors to stand D356, Hall 3A, will see a range of Renishaw’s precision position feedback systems.
As a leader in position encoders, Renishaw will highlight products including RESOLUTETM, described as the world’s first single track fine-pitch optical absolute encoder. In rotary (angle) configuration, this is capable of 32-bit resolution at 36,000 RPM or, in linear format, 1nm at speeds of 100m/s and lengths beyond 10m.
The RESOLUTE absolute optical encoder is now available with Siemens DRIVE-CLiQ interface, an innovative, powerful communications interface to connect the encoder with SINUMERIK and SINAMICS drive components. The RESOLUTE system with the DRIVE-CLiQ interface allows machine builders to achieve outstanding performance and reliability. The product determines position immediately at switch-on and so is particularly suitable for use in high-performance robotics as well as DDR torque motors requiring high levels of precision and motion control integrity. A dual-head summing variant provides immunity to axis eccentricity and bearing wander in rotary applications.
Also on display will be Renishaw’s range of TONiC compact incremental optical encoders. In a rugged and simple-to-install package, these provide the accuracy only conventionally available from fragile fine-pitch glass scale encoders. Recent additions to the TONiC range of linear and rotary encoders include optional 2 nm and 1 nm resolutions, a dual output encoder interface, and compatibility with Renishaw’s Dual Signal interface (DSi) for high accuracy rotary axes.
Renishaw will also be exhibiting a range of magnetic encoders from its associate company, RLS, based in Slovenia. The AksIM absolute magnetic encoder features excellent cost-performance, zero mechanical hysteresis, 18-bit resolution, high speed operation to 10 000 RPM and support for a range of data output formats. This encoder comprises a magnetic readhead and single-track code on an axially magnetised ring, and allows position to be acquired immediately at start-up. AksIM is suitable for a diverse range of motion control applications including pan-tilt or azimuth-elevation platforms, automation systems and medical equipment.
Renishaw will announce more products to be exhibited at Drives and Controls 2014 in the coming weeks. For more information about encoder products visit the website at www.renishaw.com/encoders.
