摘要： A position-measuring device having integrated function testing includes a position-recording unit, a processing unit, and a control-word generator. In a positional-data request, a positional-data word is first generated in the position-recording unit and output to the processing unit. There, the position data word is processed into a position value. Subsequently, a control-data word is generated in the position-recording unit according to the specification of the control-word generator and output to the processing unit. The processing unit processes the control-data word into a control value which has a defined mathematical relationship to the position value.
