Bit 7 Bit 7=0 In slave axis cascading, the arithmetic sequence is selected in such a way that
no dead times occur. A slave axis ring triggers alarm 3085 "NC CPU time
monitoring"
Bit 7=1 If bit 7 is set to 1 in MD 5016, the slave axes are entered in an execution list
in the same order as their global KOPEIN. This list is not sorted again so that
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.

Bit 7 Bit 7=1 Activation of the function ”Transformation machine data changes effective
without warm restart”. This means that a warm restart is no longer necessary
after making changes to the transformation machine data (MD 730-MD 809).
Bit 7=0 The previous functionality (compatibility), i.e. the necessity of a warm restart
after a machine data change, is active.
Bit 6 Bit 6=1 Changes may also be made to the transformation machine data when that
same data are active in a transformation.
Bit 6 Bit 6=0 Transformation machine data changes may only be made when these machine
data are not in an active transformation. In this case, a tolerance check will not
be made.
