摘要： A linear position measuring system and a method for determining an absolute position of a carriage along a slide rail are disclosed. An analog signal progression (S) based at on at least one reference point is here discretely scanned in response to a first threshold (SW1) and second threshold (SW2). The resultant digital values are stored in a first measured value register (MR1) and a second measured value register (MR2). The contents of the first and second measured value register (MR1, MR2) are compared with the respective contents of a first and second set measured value register. The reference point is output as an ideal reference point if the differential value lies within a predetermined tolerance range, and is otherwise discarded.

摘要： A linear position measuring system (10) and a method for determining a position of a carriage in relation to a slide rail (12), with an incremental scale (14) placed along the slide rail (12) and a scanner secured to the slide scale. The scanner is designed to scan a plurality of incremental markings along the incremental scale (14), wherein the incremental markings can be scanned as an essentially analog signal progression. The scanner is designed to scan the incremental markings with a variable scanning frequency. The scanning frequency can be adaptively varied in relation to a currently acquired frequency of the analog signal progression, wherein the variable scanning frequency measures at least twice the currently acquired frequency of the analog signal progression.
