Example: Position encoder feedback with a laser distance measuring device
The current position of a positioning unit is detected with a laser distance measuring device (e.g.
»DME5000«) with a Hiperface® interface. A graduation of 0.1 mm has been parameterised in the
distance measuring device.
The positioning unit is moved by 848.23 mm in an axial direction for each revolution of the slip-free
drive roll. The current motor speed is detected by a resolver.
