Single Direction Positioning
Limitation
• Single direction positioning is not performed along an axis for which no
overrun distance is set in parameter No. 5440.
• Single direction positioning is not performed along an axis for which
travel distance 0 is specified.
• 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. If positioning of linear interpolation
type is used, and the state of mirror image when a single direction
positioning block is looked ahead differs from the state of mirror image
when the execution of the block is started, an alarm is issued. When
switching mirror image in the middle of a program, disable looking
ahead by specifying a non-buffering M code. Then, switch mirror
image when there is no look-ahead block.
• In the cylindrical interpolation mode (G07.1), single direction
positioning cannot be used.
• In the polar coordinate interpolation mode (G12.1), single direction
positioning cannot be used.
• When specifying single direction positioning on a machine that uses
angular axis control, first position the angular axis then specify the
positioning of the Cartesian axis. If the reverse specification order is used,
or the angular axis and Cartesian axis are specified in the same block, an
incorrect positioning direction can result.
• In positioning at a restart position by program restart function, single
direction positioning is not performed.
M
• Single direction positioning cannot be performed for a hole machining
axis in a canned cycle for hole machining.
• Single direction positioning is not performed for an axis subject to shift
value movement in a G76 or G87 canned cycle.
T
• The G code for single direction positioning is G60, regardless of whether
the G code system is A, B, or C.
• In a multiple repetitive canned cycle for turning (G70 to G76), single
direction positioning cannot be used.
• Single direction positioning cannot be used for a hole machining axis in a
canned cycle for hole machining (G83 to G89) and rigid tapping (G84
and G88). However, single direction positioning can be used for
positioning operation.
• Single direction positioning cannot be used in a canned cycle (G90, G92,
or G94).
• In the single direction positioning mode, G07.1, G12.1, G70 to G76, and
G90 to G94 cannot be specified.
