3.2 NCU link
Frames
A link axis is permitted in a Frame command only when it is a geometry axis. The Frame
command changes only the geometry in the channel to which the link axis is currently assigned.
Speed/torque coupling, master-slave
The drives of all axes/spindles of a master-slave group must be connected to the same NCU.
The master axis can, however, be traversed as link axis for the channel of another NCU.

General information

An axis container is a circular data structure with a parameterized number of elements. These
elements together with axis containers, are designated as slots (Slot 1, Slot 2, ... Slot n). The
slots allow a variable assignment of geometry and/or special axes to machine axes. The entry
in a slot can reference an NCU-local machine axis (container axis) or a link axis (container-link
axis).
The following figure shows an axis container with four slots. The container axes refer in the
current position of the axis container to the following machine axes:
