RESOLUTE with BiSS is available in both linear and rotary (angle) encoder versions, compatible with a wide range of industry-standard controllers, drives, DROs and PC counter cards. Proprietary protocol options for RESOLUTE absolute encoders are also available RESOLUTE absolute linear encoders with BiSS
The maximum scale length is determined by the readhead resolution multiplied by the number of position bits in the serial word. For RESOLUTE readheads with fine resolution and short word length, the maximum scale length will be limited accordingly. Conversely, coarser resolutions or longer word lengths enable the use of longer scale lengths. RESOLUTE with BiSS C (unidirectional) protocol has two options for the position word length; 32 bits and 26 bits. The 32 bit position word facilitates longer lengths that can be a significant benefit, especially at fine resolutions. For 5 nm and 50 nm resolution readheads with a 32 bit position word, it is possible to use the full 10 metre scale length offered by RTLA and RSLA.
RESOLUTE absolute rotary (angle) encoders with BiSSMonolithic stainless steel RESA rings with high-precision graduations marked directly onto the periphery, also featuring large internal diameters for easy integration. Unique taper mount enables quick installation and easy adjustment to compensate eccentricity of the mounting shaft. Ultra-high accuracy REXA rings with thicker cross-section, guaranteed to achieve ±1 arc second total installed accuracy with dual readheads*. Absolute rotary (angle) encoder resolutions and speeds
Note that 32 bit resolution is below the noise floor of the RESOLUTE encoder. *REXA total installed accuracy is better than ±1 arc second on ring diameters larger than 100 mm, when installed to the specifications detailed in the REXA installation guide. For accuracy specifications for smaller rings, please refer to the REXA datasheet (available September 2009).
