14.3 Axis container (AXCTSWE, AXCTSWED)
14.3
Function
On rotary indexing machines/multi-spindle machines, the axes holding the workpiece move
from one machining unit to the next. Since the machining units are subject to different NCU
channels, the axes holding the workpiece must be dynamically reassigned to the
corresponding NCU channel if there is a change in station/position. Axis containers are used
for this purpose.
Only one workpiece clamping axis/spindle is active on the local machining unit at a time. The
axis container combines the possible connections to all clamping axes/spindles, of which
only one is active at a time for the machining unit.
The available axes that are defined in the axis container can be changed by switching the
entries in the axis container ("axis container rotation") through an increment that can be
entered via setting data (number of slots).
The command AXCTSWE or AXCTSWED is used to call the axis container rotation from the
part program.

Command to rotate an axis container
If all of the enable signals of all channels for the axes of the
container are available in the control, the container is rotated with
the container-specific increment saved in the SD41700
$SN_AXCT_SWWIDTH[<container number>].
Command to rotate an axis container where just the active
channel is effective (command version for commissioning!)
Note:
The axes entered in the container are only released if the
remaining channels, which have axes in the container, are in the
reset state.
