Fortis™是一种新的封闭编码器，它使机床构建器能够提高机床性能并增加正常运行时间，同时提高组装，维护和维修的效率。
创新堡enclosed linear absolute encoder series is designed for use in harsh environments such as machine tools. It can also be used in functional safety applications up to SiL2 and PLd.
The FORTiS encoder design is built upon industry-provenRESOLUTE™编码器技术，并对液体和固体碎屑污染物的入口提供了高阻力。它具有挤压围墙，并带有纵向连接的互锁唇封和密封端盖。读取主体通过刀片连接到密封的光学单元，该刀片沿着编码器的长度穿过Duraseal™唇部密封。线性轴运动会导致读取和光学元件穿越编码器的绝对尺度（固定在外壳的内部），而无需机械接触。
Renishaw的主要机械工程师Ian Eldred强调了一系列独特而开创性的设计功能，并加上最近引入功能安全（FS）的变体：
“The new FORTiS enclosed absolute encoder range is the culmination of years of R&D effort at Renishaw. It delivers superior repeatability, reduced hysteresis and improved measurement performance due to an innovative non-contact mechanical design that doesn’t require a mechanical guidance carriage. Five years of accelerated life testing, under the harshest conditions, has enabled Renishaw to develop and refine the new advanced DuraSeal lip seals. These offer excellent resistance to wear and machine tool lubricants, superior sealing and ingress protection up to IP64 when combined with air purge.”
He continues, “FORTiS absolute encoders also feature integrated, specially-designed tuned mass dampers that deliver class-leading 30 g vibration resistance and push the limits of what enclosed encoders can endure. Installation of FORTiS encoders is quick and easy, which will help our customers save manufacturing and servicing time. Furthermore, with the growing industrial trend towards risk reduction for systems and processes, we were committed to providing Functional Safety variants for all FORTiS enclosed encoders. We are delighted to offer FS certified products to the market so soon after launching the FORTiS range.”
Customers can choose from two different extrusion profiles to suit their space requirements.
TheFortis-S™linear encoder is the standard-sized encoder, available with measuring lengths from 140 mm to 3040 mm and is installed directly to a machined surface via flexure holes in the extrusion’s body.
The堡-N™encoder, available with measuring lengths from 70 mm to 2040 mm, features a narrower cross-section extrusion and a more compact readhead to enable installations in confined spaces. This model can be mounted directly to a machined surface via two end cap mounting holes or a mounting spar for greater rigidity.
About FORTiS™ FS enclosed encoders
某些机械安全功能，例如安全限制速度（SLS），要求编码器位置反馈在功能上是安全的。利用已经用于安全相关应用程序的编码系统可以使机器认证变得更加容易。
Renishaw has launched functionally safe variants of the FORTiS enclosed encoder series.
堡™ FS is an enclosed linear absolute encoder system certified to the following functional safety standards: ISO 13849:2015 PLd, IEC 61508:2010 SIL2, IEC 61800-5-2:2016 SIL2. It also offers all the other benefits of the cutting edge FORTiS encoder series.
Fortis FS编码器与西门子的驱动器兼安全性和BISS安全串行通信协议兼容。
Benefits of FORTiS absolute encoders
Fortis绝对编码器系列旨在强大和抵抗多种机械冲击和振动效果。所有Fortis-S编码器和Fortis-N编码器都安装在安装翼梁上时，均具有30克的额定值，可确保对最严格的环境以及要求的运动控制应用程序可靠。
除了挤出的外壳外，富富堡编码器还通过进一步的密封层保护了污染。读取的光学单元（在机柜内部运行）本身是密封的，以防止液体，SWARF和其他碎屑污染。此外，改进的Fortis编码器外壳的密封可减少空气清除系统的空气泄漏，从而降低运营成本和更长的系统寿命。
堡encoders feature a range of serial communications protocols including BiSS C, BiSS Safety, Siemens DRIVE-CLiQ, FANUC, Mitsubishi, Panasonic and Yaskawa. The encoder dimensions also ensure space and bolt-hole compatibility with a wide range of alternative current and legacy systems.
Unlike traditional installation methods, peripheral diagnostic equipment is not essential. Renishaw’s patented set-up LED and carefully designed installation accessories ensure intuitive and right-first-time installation that is substantially faster than more conventional systems, even in restricted locations.
For enhanced functionality, installers can connect the Advanced Diagnostic Tool, ADTa-100, via a standard USB connector, to a PC running Renishaw’s ADT View software. This provides a user-friendly graphical interface of advanced diagnostic information, including key encoder performance parameters such as signal strength along the axis length. A permanent record of installation data can be saved providing confidence to both machine builders and users.
Renishaw FORTiS absolute encoder systems have CE approval and are manufactured in-house using strict quality-controlled processes that are certified to ISO 9001:2015 and backed by a global sales and support network.
