Processing of interrupt routine
The "Interrupt" program is automatically started on completion of reorganization. It is treated
as a normal subroutine by the system (nesting depth etc.) and is also displayed on the
operator panel front.
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.

Flexible programming
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.
Interrupt disable DISABLE, ENABLE
The DISABLE command can be set to protect part program sections from being interrupted
by an interrupt routine. The assignment interrupt signal <-> part program is maintained but
the interrupt routine does not respond to the 0/1 signal transition.
The DISABLE command can be reset with the ENABLE command. Interrupt routines are not
activated until the next 0/1 transition of the interrupt signal.
