The following TO limiting values apply for the resulting tool length change:
Values
Maximum offset value
Software end limit switch +
offset value
Software start limit switch +
offset value
If a traversing program containing a G function for a tool offset is terminated
without the G40 function, the current additive offset is retained.
The additive value can then be reset to zero only together with the external
(offset) value in mode 16 (see Section 5.3.16).
Entry of a new external offset in mode 15 also resets the additive value to
zero.
• G40: Disable tool offset
The G40 function disables all positive and negative tool offsets in a
traversing program.
• G43: Enable positive tool offset
The G43 function enables a positive offset of the length specified in the
machine data.
• G44: Enable negative tool offset
The G44 function enables a negative offset of the length specified in the
machine data.
