Renishaw introduces its true-absolute multi-DoF encoder system, featuring the new RXMA30 1.5D scale

This versatile system offers advanced multi-DoF position measurement in up to six degrees of freedom (6DoF), making it well-suited to high-performance motion systems, where accuracy, speed and repeatability are critical.

The RXMA30 scale is designed to ensure highly repeatable metrology under demanding thermal and dynamic conditions. With dedicated, separate scale tracks, machine designers can directly measure motion in the X and Y axes, without the need for complex signal processing. Absolute encoder technology removes the need for homing routines, which are often difficult on the Y axis because users have limited control of motion.

The technology allows machine builders to detect and compensate for error sources - such as the straightness of linear guideways, small translational deviations, and rotational errors - which are often unavoidable in precision motion systems. By enabling in-process compensation of these errors, Renishaw’s multi-DoF encoder solution supports improved process capability and higher component yields.

Renishaw’s multi-DoF encoder approach streamlines system architecture while maintaining compatibility with a wide range of serial interfaces and motion control platforms. The system provides significant versatility, enabling designers to tailor scale and readhead configurations to meet specific application requirements.
