Abstract
A position encoder system (e.g., including a linear encoder) is configured to rapidly provide encoder position data in response to position trigger signals that are received from a host motion control system at predictable times (e.g., according to a preset frequency, etc.) A pre-trigger lead time is determined that is a fraction of a duration of a defined encoder position sample period. A current instance of the encoder position sample period is then initiated at the pre-trigger lead time before a next predictable time of the position trigger signal. A current position trigger signal is then received (e.g., near the middle of the current instance of the encoder position sample period) from the host motion control system. The average effective sample time of the current instance of the encoder position sample period coincides with the actual timing of the current position trigger signal within an allowed tolerance window.
