4.2.2.28 Object 4ad1h: Sensor Positioner – Position Offsets
With the position offset, you can create a reference system with
an absolute reference point for the position of the sensor slides.
This reference point can be a distinctive point on the machine
(e.g. machine wall or center of the machine). As an alternative,
you can also use the park position of a sensor slide or the middle
of the sensor positioner as reference point. The set offset value
(position offset) is added to the current position of the sensor
slide in the controller and then results in the absolute distance to
the reference point selected.
The procedure for adjusting the position offsets is described in the
installation and commissioning manual of the ekr 500 digital Unit
Touch controller (document number MD.497).
