System variables
An untraceable section can be detected in the parts program with
Automatic interrupt pointer
The automatic interrupt pointer automatically defines a previously defined coupling type as
untraceable. The machine data for
● electronic gearbox with
● axial leading value coupling with
are used to activate the automatic interrupt pointer. If the programmed interrupt pointer and
interrupt pointer activated with automatic interrupt pointers overlap, the largest possible
untraceable section will be generated.

Function
If you interrupt the program run and retract the tool during the machining operation because,
for example, the tool has broken or you wish to check a measurement, you can reposition at
any selected point on the contour under control by the program.
The REPOS command acts in the same way as a subprogram return jump (e.g. via M17).
Blocks programmed after the command in the interrupt routine are not executed.
