POSITION MEASUREMENT ENCODER AND METHOD OF OPERATION |
摘要 |
A method of operating a position encoder apparatus, comprising a scale having features defining position information and a readhead for reading the scale. The method comprises: calculating extrapolated position information from at least one previous reading of the scale; comparing an extrapolated position with a position calculated from a reading of the scale to determine any discrepancy between them; using the extrapolated position information whether or not there is a discrepancy; and maintaining a record of any discrepancies. |
