1. Single direction positioning is not performed along an axis for which
no overrun distance is set in parameter No. 5440.
2. Single direction positioning is not performed along an axis for which
travel distance 0 is specified.
3. The mirror image function is not applied in a parameter–set direction.
Even in the mirror image mode, the direction of single direction
positioning remains unchanged.
4. Single direction positioning cannot be used for a hole machining axis
in a hole machining canned cycle. However, single direction
positioning can be used for positioning operation.
5. In the cylindrical interpolation mode (G07.1), single direction
positioning cannot be used.
6. In the polar coordinate interpolation mode (G12.1), single direction
positioning cannot be used.
7. Single direction positioning is not performed for an axis along which
a movement is made by a shift amount in a G76 or G87 canned cycle.
(M series)
8. The G code for single direction positioning is G60, regardless of
whether the G code system is A, B, or C. (T series)
9. In a multiple repetitive turning canned cycle (G70 to G76), single
direction positioning cannot be used. (T series)
10.In a grind canned cycle (G71 to G74), single direction positioning
cannot be used. (T series)
11.In a canned cycle (G90, G92, G94), single direction positioning cannot
be used. (T series)
If a move command is specified on an angular axis in angular axis control,
a compensation command is output for the orthogonal axis. Let Yp be a
move command for an angular axis, and let ( be the inclination angle of
the angular axis. Then, the compensation command Xa for the orthogonal
axis is:
Xa = –YpStan q
Movement in the plus direction
+X (orthogonal axis)
Compensation in the minus direction: Xa
Move command in the plus direction: Yp
+Y (angular axis)

q (inclination angle)
