6 NC Machine Data (NC MD), NC Setting Data (NC SD)
6.2 General machine data (general data)
d. It must be possible to program the axes of one coupled axis grouping in the same
channels MD 576* bits 7 to 0 and MD 580*, bits 7 to 0.
e. The axes in a coupled axis grouping must be available
(NC MD 564* bit 7 = 1).
f. None of the axes of a coupled axis grouping is allowed to be a fictitious axis
(NC MD 564* bit 6 = 0).
g. One leading axis can couple several axes.
Example:
Coupled
axis
NC MD
883
0
Please also refer to the Programming Guide.
h. The leading axis of a coupled axis grouping cannot at the same time be the coupled
axis of the same grouping (observe also NC MD 5156 to 5188).

i. The leading axis of a coupled axis grouping can also be the coupled axis of another
grouping (observe also NC MD 5156 to 5183).
j. A leading axis cannot couple itself.
Coupled
axis
NC MD
883
0
k. A coupled axis can be coupled with several leading axes if the leading axes are in other
coupled-axis groupings and these coupled-axis groupings are not active at the same
time.
The definition of the coupled-axis groupings can be changed with warm restart without
POWER ON (see Section Functional Descriptions for a more detailed description of warm
restart).
