Renishaw: TONiC™ T20x1 RESM Angle Encoder System (T2001-10A Series)

TONiC is Renishaw's super-compact, non-contact encoder system that offers speeds up to 10 m/s and, when combined with the Ti interface, resolutions down to 1 nm for both linear and rotary applications. TONiC systems are quick and simple to install with wide set-up tolerances and calibration at the push of a button. TONiC's dynamic signal processing gives improved signal stability with ultra-low Sub-Divisional Error of typically <±30 nm to help realize superior motion control performance.

RESM is a one-piece stainless steel ring with 20 µm pitch graduations marked directly on the periphery, featuring the IN-TRAC™ optical reference mark. Two versions are available in a wide range of sizes (Ø52 mm to Ø550 mm). ‘A' section rings, which offer an impressive installed accuracy and feature a taper mount system which reduces the need for highly toleranced machined parts and eliminates eccentricity. ‘B' section thin rings, which are low inertia and mass, are also available. Both 'A' and 'B' section rings have a large internal diameter for flexible integration. The non-contact format eliminates backlash, shaft wind-up (torsion) and other mechanical hysteresis errors that are inherent in traditional enclosed encoders.

Why choose this encoder system?

Dirt immunity

High tolerance to dirt, scratches and greasy fingerprints and speeds of 10m/s mean that TONiC is ideal for more challenging applications. Furthermore, the non-contact RESM operates without friction or wear ensuring excellent reliability.

Ultimate reliability and performance in a compact size

For ultimate reliability, consistent performance and high dirt immunity, TONiC readheads incorporate third-generation filtering optics tuned for even lower noise (jitter) and now further enhanced by dynamic signal processing including Auto Gain Control and Auto Offset Control. This combination – all incorporated inside the readhead - provides signals of unrivalled purity and ultra-low Sub-Divisional Error of typically <±30 nm. The result is smoother velocity control for improved scanning performance and increased positional stability; essential parameters for so many applications, all in a compact readhead.

Quicker and easier installation

A set-up LED on the readhead gives a visual indication of signal size and an optional diagnostic kit allows remote checking of the system performance when the readhead is concealed within the machine. Calibration of the reference mark and incremental signals is done at the push of a button with no mechanical adjustment or additional diagnostic tools. The IN-TRAC customer-selectable optical reference mark is embedded in the incremental scale for compact dimensions and simplified alignment. This yields a reference mark output that is bi-directionally repeatable to unit of resolution over the full operating temperature and speed range.

Interface options

TD (dual resolution) interface

  • Selectable dual-resolutions quadrature output.

  • Ideal for applications that require high speed movement combined with finer precision motion.

DOP (dual output) interface

  • Provides simultaneous digital quadrature and 1 Vpp signals.

  • Designed for applications requiring one or more operations to be synchronized with a motion axis.

DSi (Dual Signal interface)

  • Renishaw's DSi combines the incremental signals from two TONiC readheads on a RESM ring (REST ring for partial rotation applications) to compensate for the effect of bearing wander and eliminates odd error harmonics, including eccentricity to give total l installed accuracy of typically ±2.0 arc second.
