10.5.6 Indexed axes/"Hirth" axes
Indexed axes are rotary or linear axes, which can be traversed to indexed positions by index
program instructions.
These indexed positions are approached in JOG mode.
In "normal" positioning, every position can be approached.
Note
Traversing to indexing positions using the parts program or manually is only effective if the
corresponding machine axis has been successfully referenced.
Hirth axes are indexing axes with Hirth tooth system. These axes are rotary or linear axes,
which may only be traversed to defined positions, the indexing positions, within the
traversing range (MD30505 HIRTH_IS_ACTIVE).
The indexing positions are stored in tables.
