Parameterization for evaluation of the measuring probe
The EL5072 offers the option to evaluate measuring probes in LVDT and half bridge design or inductive angular position sensors in RVDT design. The measuring signal range is adjusted automatically. The measured value is output directly as a position value via the process data 0x60n01:01 "Position".
For correct output of the measured value, all sensor parameters must be entered in the configuration data.

Please refer to the data sheet or the specification of the measuring probe used. For the commissioning an RVDT follow the corresponding instructions.
Other available parameterization options: filter function; user calibration via offset and gain values or via a lookup table; reversal of the measuring direction.
