White paper: Mounting encoder scales for optimum thermal performance
This white paper discusses the thermal performance of Renishaw's linear encoder scales. It includes options on how to calculate and compensate for thermally induced strains. It also explains how an expansion mismatch between the scale and the underlying machine substrate can impact on the overall performance of the encoder system. Guidance is given to customers about which scales to choose.[965kB]

White paper: The accuracy of angle encoders
Many automation systems rely on precision rotary motion, such as rotary format computer-to-plate (CTP) pre-press machines, machine tool A, B & C axes, surface mount machines and wafer handling and inspection equipment. Different applications demand different combinations of performance and features to optimise their function – some require accuracy, others repeatability, high resolution or low cyclic error for velocity loop control. Typically customers need an encoder that offers the optimum balance of specification and function, and there is a bewildering array to choose from. Yet few are capable of meeting all requirements.[1.4MB]
