Application note: Principles of XR20-W measurement (pdf)
File size: 331 kB Language: English Part number: H-9920-0427
This application note describes how the XR20-W system allows the measurement of rotary axes angular positioning. The true angular position of the axis is calculated from a combination of the rotational position recorded by the XR20-W's internal encoder and measurements from a laser and angular optic mounted on the XR20-W axis.
