Figure 2-11 Example: Axis container CT1 with four slots
Rules
The following rules must be observed with regard to axis containers:
● All machine axes of an axis container may be assigned to just one channel axis at any
one time.
● Multiple slots of an axis container must not reference the same machine axis.
● At any one time, only one channel is authorized to write to a machine axis, directly or via
a container axis.
● Several geometry and/or special axes of a channel can also be assigned to the container
axes of an axis container.
Assignment: Geometry or special axis → container axis
In the logical machine axis image MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB, a
container axis can be assigned as a machine axis via container and slot to a geometry or
special axis, e.g. CONTAINER "CT1", slot "1":
MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB[ n ] = CT1_SL1
During the traversing of the geometry or special axis, the machine axis assigned at this time
to slot 1 then traverses.
Axis container rotation
An axis container rotation is always performed when all channels involved on the axis
container have granted their enable with a program command. After the axis container
rotation, other machine axes are assigned to the geometry or special axes of the channels.
The setting data specifies the increment of an axis container rotation.
See Section "Parameterization (Page 103)".
