Link Axes - Siemens SINUMERIK 828D Function Manual

Example: Channel axis gap
Channel axis B is not assigned a machine axis in the following example.
Figure 10-6 Axis configuration with channel axis gap (excerpt)
Special situations: Channel axis gaps
Regarding channel axis gaps, the following also have to be taken into account:
• Channel axes without assigned machine axes (channel axis gaps) are, regarding the number and indexing of
the channel axes, treated just like normal channel axes with associated machine axes.
• If a channel axis without assigned machine axis (channel axis gap) is defined as geometry axis, then this is
rejected without an alarm.

Link axes

Meaning
A link axis is a machine axis that is not on the NCU from which it is traversed. The identifier of a local machine
axis is not entered in the machine data for the logical machine axis image of the traversing NCU, but the NCU
and machine axis identifier of the NCU to which it is physically connected.
As an example, machine axis AX1 of NCU2 should be traversed from NCU1:
• NCU1: MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB[n] = NC2_AX1
Precondition
The NCUs involved must be connected using link communication as precondition for using link axes. The link
axes and link communication functions are described in detail in:
