P2: Positioning axes10.2 Own channel, positioning axis or concurrent positioning axisExtended Functions604 Function Manual, 03/2013, 6FC5397-1BP40-3BA1DependenciesPositioning 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 G0 path axes traverse as positioning axes in one of twodifferent modes● No rapid traverse override● The following interface signals act on the entire channel and therefore on positioningaxes:– DB21, ... DBX7.1 (NC start)– DB21, ... DBX7.3 (NC stop)– DB21, ... DBX7.7 (reset)– DB21, ... DBX6.1 (read-in disable)● 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 thesearch run serves as a container for setting all axes.● Group 1 (modal movement commands) of the G functions G0, G1, G2, ...) does not apply topositioning axes.References:Programming Manual Fundamentals.ApplicationsThe following are typical applications for positioning axes:● Single-axis loaders● Multi-axis loaders without interpolation (PTP → point-to-point traversing)● Workpiece feed and transportOther applications are also possible:● With G0 workpiece delivery and workpiece transport can travel to their end pointsindependently of one another.● On machines with several machining processes in sequence: Significant reduction inindividual machining steps due to block change in the braking ramp of the single-axisinterpolation.NotePositioning axes are not suitable for multi-axis loaders that require interpolation betweenthe axes (path interpolator).
