# Reference point offset for control measuring system (P-AXIS-00418)

P-AXIS-00418 | Reference point offset for measuring system
Description | The value range of the sensor measuring system can be moved by an offset via this machine data item. This is necessary in the case of absolute position sensors, for example, to define the reference point, i.e. the sensor position that is adjusted if the spindle touches the ideal workpiece surface.
