Abstract
A position measuring device includes: a graduation carrier on which a measuring graduation is provided; a scanning unit for generating position-dependent scanning signals by scanning the measuring graduation; and a signal processing unit for processing the scanning signals into position signals. A monitoring unit is provided, to which at least one signal to be monitored is supplied, and by which a modification signal is able to be output to a modification unit based on the monitoring of the signal to be monitored. At least one position signal is supplied to the modification unit, and the position signal is able to be modified by the modification unit for the transmission of at least one status report and able to be output as output signal to subsequent electronics. The modification is implemented based on the modification signal by adding a disturbance variable to the at least one position signal.
