# Default name of an axis (P-AXIS-00297)

P-AXIS-00297 | Default name of an axis
Description | The parameter defines the default name of the axis in the system and should therefore be unique system-wide in the same way as the logical axis number. It is used for:

- Name conflicts in connection with extended axis exchange operations [PROG//Section - Axis exchange commands].
- In robotics in connection with the programming of axis-specific movements (P-CHAN-00253).

Besides this, the default name has no meaning because the axis name is defined in the channel configuration (P-CHAN-00006).
