A) If the components of the direction vector of a rotation axis are in a single
direction (type A)
This is a case in which the rotation axis rotates about any one of the
three basic axes.
1) Set the axis numbers for the rotation axis, linear axis 1, and linear
axis 2.
2) Set 0 for the angle.
3) The rotation axis must satisfy the following:
- The rotation axis rotates about an axis orthogonal to the plane of
linear axes 1 and 2.
- The rotation of the rotation axis in the plus direction is its rotation
from the plus direction of linear axis 1 to the plus direction of linear
axis 2.

B) If the components of the direction vector of the rotation axis are in two
directions (type B)
This is a case in which the rotation axis rotates about an axis on the
plane formed by any two of the basic three axes.
1) Set the axis number for the rotation axis and linear axes 1, 2, and 3.
2) Linear axes 1, 2, and 3 are supposed to form a right-handed system
in that order.
3) The angle must satisfy the following:
- Rotation is on the plane of linear axes 3 and 1.
- The rotation of the angle in the plus direction is its rotation from
the plus direction of linear axis 3 to the plus direction of linear axis
1.
- The angle assumed at the time of a match with the direction of
linear axis 3 is 0 degrees.
4) The rotation axis must satisfy the following when the angle is 0
degrees:
- The rotation axis rotates about an axis orthogonal to the plane of
linear axes 1 and 2.
- The rotation of the rotation axis in the plus direction is its rotation
from the plus direction of linear axis 1 to the plus direction of linear
axis 2.
