P2: Positioning axes
10.2 Own channel, positioning axis or concurrent positioning axis
Dependencies
Positioning axes are dependent in the following respects:
● A shared part program
● Starting of positioning axes only at block boundaries in the part program
● With rapid traverse movement
● No rapid traverse override
● The following interface signals act on the entire channel and therefore on positioning
● Alarms specific to program and channel also deactivate positioning axes.
● Program control (dry run feed, program test, DRF, ... etc.) also act on positioning axes
● Block search and single block also act on positioning axes.
● The last block with a programmed end-of-motion criterion that was processed in the
● Group 1 (modal movement commands) of the G functions

Applications
The following are typical applications for positioning axes:
● Single-axis loaders
● Multi-axis loaders without interpolation (PTP → point-to-point traversing)
● Workpiece feed and transport
Other applications are also possible:
● With
● On machines with several machining processes in sequence: Significant reduction in
Note
Positioning axes are not suitable for multi-axis loaders that require interpolation between
the axes (path interpolator).
