2.7.9 GRENZEN
Position limit value min-max.
The position limit values are software end limits and correspond to the absolute position limits, within which the set values and
actual values (in absolute form) must be moved. Each new target position is checked with these limits. They always refer to the
machine zero point; therefore they must be corrected using the reference measurement offset.
