FORTiS-S enclosed encoder system with multiple readheads

Summary of UK declaration of conformity 7
Overview of the FORTiS-S FS encoder
system with multiple readheads
This system is an enclosed linear optical encoder designed for use in harsh industrial environments
where high-precision feedback and metrology are required. It is suitable for applications where
various slideway mechanisms are common to a particular linear axis and require multiple
readheads to provide feedback.
Based upon Renishaw’s award-winning absolute technology, the rugged non-contact design has no
internal moving parts, such as bearings or wheeled readhead carriages, thus improving the overall
reliability. Additionally, hysteresis and backlash errors associated with mechanical contact system
designs are reduced.
In addition to enhanced breakage resistance, the robust steel scale has a coefficient of thermal
expansion similar to the base material used in the majority of machines, reducing errors due to
thermal effects whilst increasing measurement certainty.
Renishaw’s patented set-up LED provides instant verification of the encoder’s signal strength
and therefore its accurate alignment. This intuitive procedure significantly reduces the need for
additional peripheral diagnostics equipment during installation. When combined with Renishaw’s
carefully designed installation accessories, these unique tools make installation easier and faster
compared to traditional methods, whilst building confidence in a right-first-time installation.
For information regarding FORTiS FS encoder systems with single readheads please refer to the
FORTiS-S FS enclosed encoder system Functional Safety installation guide and safety manual
