System and method for delay calibration in position encoders

Image Number 10 for United States Patent #6639529.

Systems and methods are provided for calibrating a sample delay time between a position request time from a host computer and a position encoder sample time. The position encoder includes a readhead with a transducer and transducer electronics, and encoder interface electronics which exchange data and commands with the readhead and with the host computer. The transducer electronics may lack a clock capable providing a sufficiently consistent sample delay time. To provide a consistent sample delay the interface electronics measures an inherent sample delay time based on signals from the readhead during a calibration mode. The difference between the inherent delay time and the desired delay time is saved and inserted by the interface electronics during position measurement such that the calibrated sample delay time is consistently the desired sample delay time.
