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