Position-measuring device and method for position measuring
First Claim
1. A position-measurement device including integrated function testing, comprising:
- a position-recording unit;
a processor unit, the position-recording unit connected to the processor unit; and
a control-word generator;
wherein the position-recording unit is configured to generate a positional-data word, including an instantaneous position value, and a control-data word, the positional-data word and the control-data word outputtable to the processor unit, the processor unit configured to generate a position value from the positional-data word and a control value from the control-data word, the control value and the position value having a defined mathematical relationship to one another, the control-word generator configured to adjust whether the positional-data word or the control-data word is output by the position-recording unit.

Abstract
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.
