The definition of these coupled axis groupings determines which axis is to be coupled when
a leading axis is traversed in Jog mode or under program control.
It is possible to define a maximum of 9 coupled axis groupings. See also MD 5019, bit 3.
The number of the relevant axis must be entered as follows in the MD:
0
1
2
:
The coupled motion combinations (NC MD 5156 to 5182) determine how coupled axis
groupings are to perform (coupled motion in same direction /in opposite directions/...) and the
G functions with which they can be activated. All coupled-axis groupings are activated with
G151 ... G159. All the axes that have been declared as leading axes in the MD can be
programmed, even if they have been declared as coupled-motion axes in the grouping.
For coupled axis groupings the following must be observed (alarm 84 is issued if an error
occurs):
a. The axes in a coupled axis grouping must be in the same mode group.
b. The axes in a coupled axis grouping must have the same position control resolution and
display resolution.
c. The axes in a coupled axis grouping must be of the same axis type:

1) Use of the Warm Restart function enables activation of other assignments without the necessity of a
Power On. Refer to Section Functional Descriptions for a detailed description of the Warm Restart function.
