Precondition

Procedure
Note
When you exit the editor using the "Close" softkey, you return to the "Program manager"

6.6 Repositioning axes
After a program interruption in the automatic mode (e.g. after a tool breaks), you can move
the tool away from the contour in manual mode.
The coordinates of the interrupt position will be saved. The distances traversed in manual
mode are displayed in the actual value window. This path difference is called "Repos-offset".
Resuming program execution
Using the "Repos" function, you return the tool to the contour in order to continue executing
the program.
The interrupt position is not passed as it is blocked by the control system.
