Axis replacement via axis container rotation
By rotating the axis container, the assignment of a channel axis can change to assignment of
a machine axis. The current diameter programming status is retained however for the channel
axis after the rotation. This also applies to the current channel and axis status, because the
status is the same for all axes of the axis container at the time of the machine data "putting
into effect" the status from MD30460 $MA_BASE_FUNCTION_MASK.

Examples

Example 1
X is a transverse axis defined via MD20100 $MC_DIAMETER_AX_DEF.
Y is a geometry axis and U is an additional axis. These two axes are additional transverse
axes with diameter specifications defined in MD30460 $MA_BASE_FUNCTION_MASK with
bit 2 = 1.
DIAMON is not active after power up.

Example 2
Transverse axes with diameter specification applied as in the previous example.
X and Y are located in channel 1 and are also known in channel 2; i.e. permitted for axis
replacement.
