18.3 Online tool offset
Supplementary conditions
● The online tool offset is superimposed on the programmed axis motion, allowing for the
● The pending offset is traversed at JOG velocity, allowing for the maximum acceleration.
● The valid online offset is deleted on reference point approach with G74.
● The fine offset is not deselected for tool changes with M6.

defined limit values (e.g. velocity).
If a DRF offset and online offset are active simultaneously for an axis, the DRF offset is
considered first.
In case of FTOCON the following channel-specific machine data is taken into account:
MD20610 $MC_ADD_MOVE_ACCEL_RESERVE
An acceleration margin can thus be reserved for the movement which means that the
overlaid movement can be executed immediately.
