Some Extended Functions are assigned fixed levels, e.g. STO is not used in group 1 for the
feed axes. In this case, the function must be permanently deselected or have level "1",
"Statically inactive" in STARTER. On the other hand, one of the four SLS values is always
active, when nothing with higher priority is pending. In this case, the function must be
permanently selected or have level "0", "Statically active" in STARTER. This fact is illustrated
in the following diagram for the feed axes:
