dead times can occur with slave axis cascading. The desired sequence can be
set using the global KOPEIN sequence.
A slave axis can be pushed to the end of the execution list by (online) a global
KOPAUS and subsequent global KOPEIN. With SW 3 and higher it is only
possible to resort in this way by exchanging the global axis numbers.
