Detailed Description
2.7 Program operation mode
Exceptions when reorganization is not possible:
• In thread cutting blocks
• With complex geometries (e.g., spline or radius compensation)
Processing of interrupt routine
The "Interrupt" program is automatically started on completion of reorganization. It is treated
by the system like a normal subroutine (displayed on the operator interface, nesting depth
etc.)
End of interrupt routine
After the end identifier (M02, M30
axis traverses by default to the end position programmed in the part program block following
the interruption block.
A REPOS instruction must have been programmed at the end of the "Interrupt" routine if
return positioning to the point of interruption is required, e.g. REPOSL M17

SAVE command
If the SAVE command has been used to define the interrupt routine, the G codes, frames
and transformations previously active in the interrupted part program become operative
again as soon as the interrupt routine is ended.
