2.7 Axis container

2.7 Axis container
Axis container
An axis container can be imagined as a circular buffer in which the assignment
● Local axes and/or
● link axes
are assigned to channels.
Container axes
Axes in an axis container are also referred to as container axes.
Assignments can be "shifted" ("rotation" of the circular buffer) by means of program
commands.
The term axis in this case refers to both axes and spindles.
All machine axes in the axis container must be assigned to exactly one channel axis at any
given point in time.
Note
Rotation of the drum or rotary table is analogous to the rotation of the circular buffer with the
assigned axis entries.
Container link axes
Entries in an axis container can refer to machine axes that are installed in a different NCU
than the remaining container axes. Such container axes are also denoted as container link
axes.
Reference to axis container
In addition to the direct reference to local axes or link axes, the link axis configuration
described in Section "Configuration of link axes" also allows direct references to axis
containers in the logical machine axis image.
This type of reference consists of:
● Container number
● a slot (circular buffer location within the container)
The entry in a circular buffer location contains:
● a local axis or
● a link axis
(either axis or spindle).
