- Page 6 interface installation drawing quick-start guide Dimensions and tolerances in mm This section is a quick-start guide to installing a TONiC system. More detailed information on installing the system is contained in the following sections of the installation guide. INSTALLATION Ensure scale, readhead optical window and mounting faces are clean and free from obstructions. 33.3 If required, ensure reference mark selector magnet is correctly positioned.
- Page 7 Installation Mounting Step 2 REXM/REXT should be flange mounted onto a flat Clean the mounting face on the lower side surface, this eliminates all installation errors except of the REXM/REXT. Clean the mating eccentricity, which can be compensated using twin surface on the mounting shaft.
- Page 8 Alternative method -using adjustment screws Step 3 Mounting ‘Slot’ fiducial It is essential that 4 adjustment screws are used, aligned to the 4 fiducial points (indicated by a ‘slot’ or ‘dimple’ mark machined into the front face of the ring). IMPORTANT: To achieve the highest accuracy, the ring must not be distorted.
- Page 9 Ring orientation for partial arc applications The partial arc DSi is based on a ring with two reference marks opposite each other. The ring must be installed so that when the ring rotates only H1 can see R1 and only H2 can see R2. Small angular movements Large angular movements (<357°) To allow the DSi to operate with very small angular movements the ring must be mounted in a certain...

Where V = maximum linear speed (m/s) and D = external diameter of REXM/REXT (mm) Angular speed (rev/min) = π Renishaw encoder systems have been designed to the relevant EMC standards, but must be correctly integrated to achieve EMC compliance. In particular, NOTE: TD maximum speeds are resolution dependant as defined above. - Page 17 RENISHAW and the probe emblem used in the RENISHAW logo are ® registered trademarks of Renishaw plc in the UK and other countries. apply innovation is a trademark of Renishaw plc. © 2007-2023 Renishaw plc All rights reserved...
