7515 Master rotation axis number
[Input type] Parameter input
[Data type] Integer
[Valid data range] 0 - Max 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.)
A- and B-axes (The tool axis is the Z-axis, and the A-axis is the master.)
