NOTE
A hypothetical axis is also counted as a controlled
rotary axis.
<Hypothetical axis>
In some cases, it is convenient to use an imaginary
rotary axis whose angle is fixed to a certain value.
For example, suppose that a tool is mounted in a
tilted manner through an attachment. In such a
case, the rotary axis considered hypothetically is a
hypothetical axis. Bits 0 and 1 of parameter No.
19696 determine whether each rotary axis is an
ordinary roatry axis or a hypothetical axis.
