Lead Link Axes - Siemens SINUMERIK 828D Programming Manual

Axis container
An axis container is a circular buffer data structure, in which local axes and/or link axes are
assigned to channels. The entries in the circular buffer can be shifted cyclically.
In addition to the direct reference to local axes or link axes, the link axis configuration in the
logical machine axis image also allows references to axis containers. This type of reference
consists of:
● a container number and
● a slot (circular buffer location within the container)
The entry in a circular buffer location contains:
● a local axis or
● a link axis
Axis container entries contain local machine axes or link axes from the perspective of an
individual NCU. The entries in the logical machine axis image
(MD10002 $MN_AXCONF_LOGIC_MACHAX_TAB) of an individual NCU are fixed.

Lead link axes

A leading link axis is one that is interpolated by one NCU and utilized by one or several other
NCUs as the master axis for controlling slave axes.
An axial position controller alarm is sent to all other NCUs, which are connected to the
affected axis via a leading link axis.
