[Data type] Word
[Valid data range] 0 – Number of controlled axes
When a machine does not have the rotation axis that turns about the tool
axis, the axis number of a rotation axis used as the master axis is set. For
machines not using the master–axis configuration, 0 is set.
When the tool axis direction is controlled by two rotation axes, neither of
which turns about the tool axis, one of the rotation axes is mounted on the
other rotation axis as shown in the figure below. In this case, the rotation
axis on which the other rotation axis is mounted is called the master axis.
A– and B–axes (The tool axis is the Z–axis, and the B–axis is the master.)
