Such container axes are also denoted as container linkaxes.Reference to axis containerIn addition to the direct reference to local axes or link axes, the link axis configurationdescribed in Section "Configuration of link axes" also allows direct references to axiscontainers 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).
