The truly new absolute grating system includes two forms: linear grating and circular grating.
It has non-contact characteristics and fine pitch performance. The resolution is at top speed of /.
Built-in location verification algorithm. Unique single-channel scale with loose installation tolerances and excellent resistance to contamination.
R is a true absolute, fine pitch grating system. It has extremely strong anti-fouling ability, and its extraordinary technical indicators are a new breakthrough in the field of position feedback. It is the world's first absolute encoder capable of achieving bit resolution at rpm speeds. The system delivers market-leading resolution in linear and angular encoding applications, achieving resolution at the highest speeds.
Determine absolute position immediately after turning on
R reads a unique single-code scale reading. Another attractive advantage of R for machine designers is that absolute position can be acquired immediately after turning on. No backup batteries required. There is no need to return to the home position at all. R’s combination of ruggedness, ultra-high speed and ultra-high resolution is increasingly attracting interest from manufacturers of high-performance lathes, as well as manufacturers of low-speed axes that require the highest levels of precision and motion control.
Integrating exceptional positional stability and motion control
The R is able to serve a wide range of markets because it offers much more than just high speed and high resolution. The R? absolute encoder uses a fine pitch scale read by a new precision optics. Its outstanding low noise performance (jitter R) ensures exceptional positional stability, while the inherent characteristics of the enhanced detection method enable extremely Low electronic interpolation error(). Therefore, when using this system, the CNC machine tool will process parts with a higher surface finish. In applications that maintain a fixed position, the scanning and speed control of linear motors or rotary direct drive equipment will be better, and the servo will be super rigid.
Advantages of single code track absolute scale
R does not use the traditional double code track side by side (one is incremental, the other is absolute) method, because this method requires a small amount of angular alignment There is an inherent problem of phase shift when deviation occurs. In contrast, this new absolute encoder uses a single-channel absolute scale that combines absolute position and built-in phase information into a single code. This technology allows the R to have looser mounting tolerances, so installation is quick and easy, with excellent long-term stability, even when the motion axis appears to dwell or move over time. There is a built-in installation indicator light on the readhead to further assist installation and diagnostics.
Absolute linear encoder options
R's linear encoders offer a variety of scale options. r? Because the steel scale has zero expansion and accuracy when the length is reached. To achieve high performance in the long axis and significantly greater robustness than glass scales, R stainless steel scales are available, which provide the highest overall accuracy over the length. In addition, for the quickest and most convenient installation, R? and R band scales are available with high accuracy.
Absolute rotary encoder options
Rotary encoders also available to suit every need R rotary encoders feature bolt holes that are compatible with Renishaw's leading ? R rotary encoders and are available in standard diameters from to, Larger sizes are also available. Similar to the R, the R rotary grating has an easy-to-design large through hole and a patented tapered mounting method, which enables simple, fast and precise eccentricity adjustment while greatly reducing shaft preparation costs.
Ensuring excellent reliability and safety
Picture Function Safety Mark R's grade-sealed readhead can remove stains on the scored surface by wiping, ensuring optimal reliability. The precision optical filtering provides excellent resistance to contamination, which is further enhanced by the wide redundancy of the scale encoding. The readhead's built-in independent position verification algorithm ensures safety. The algorithm proactively checks every reading, alerting you to any potential problems before they reach the controller. The innovatively designed readhead also contains a temperature sensor to measure heat build-up. If the readhead temperature exceeds +°C, an alarm signal is issued to provide additional protection for the system. In addition to alarms, signal monitoring, position checks and speed monitoring are constantly carried out inside the readhead.
R conforms to, class, standard
