T1: Indexing axes
16.1
Brief Description
As indexing axes
When machine axes only traverse between a certain number of fixed positions, these positions
can be parameterized as indexing positions. In NC programs, these machine axes, then known
as indexing axes, can be traversed with reference to indexing positions using special
commands.
Typical applications for indexing axes include tool magazines, for example (tool revolver, tool
chain magazines or tool cartridge magazines). The magazine locations of the tools are
parameterized as indexing positions.
It is possible to traverse an indexing axis in the following operating modes:
● AUTOMATIC
● MDI
● JOG
● JOG / INC1, INC10, ... INCvar

16.2.1
Traversing of indexing axes in the AUTOMATIC mode
Traversal to selected positions
Using the general traversing commands ( G90, G91, AC, IC, ...) an indexing axis can be
traversed to any position within the traversing range of the machine axis.
Traversing to indexing positions
Using the specific traversing commands for indexing axes, it is ensured that only the
parameterized indexing positions are approached. See Chapter "Programming (Page 823)".
16.2.2
Traversing of indexing axes in the JOG mode
In the JOG mode, the indexing positions are only taken into account after referencing/
synchronizing the active measuring system of the indexing axis.
