4.2.11 POSITION OFFSET IN Z-AXIS (G43, G44, G49) (Cont'd)
(5) Z-axis offset commands are programmed as follows:
(a) (G01)
IG43
(G44) Z... H...; [
With this command, the offset memory content designated by H is added (or subtract-
ed) to or from the Z command position, and the movement is made to the corrected
position.
(b)[(G01) Z...;
G43(G44) H...;
With this command, the offset value designated by H only is covered by the Z motion.
(c) [G43(G44) Z-.. H...;
i
[H...;
With this command, the H motion covers the difference between the offset prior to
command (2) and the new offset.
(6) When programming G43, G44, G49, the 01 group G code must be G00 or G01. When G02
or G03 is programmed, the alarm state occurs.
NOTE
If a G92 command involving Z-axis is commanded, while a Z-axis offset is
under execution, the offset is cancelled. In principle, specify G92 with an
offset cancelled state.
