End of interrupt routine
After the end identifier (
M02
,
M30
,
M17
) of the Interrupt routine has been processed, the 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.
N104 REPOSL M17

9.10.1.3 Interrupt routine with REPOSA
If an interrupt routine with
REPOSA
triggered by the PLC (block FC9) "interrupted" in channel status in program
operation is completed, then the following sequence is typical:
1. Before the re-approach to the contour, the controller stops and goes to program status "Stopped". The
following NC/PLC-interface signal is set:
DB21, ... DBX318.0 (ASUB is stopped)
2. The operator presses the START key. Thereupon, the signal DB21, ... DBX318.0 is reset and the re-approach
motion starts.
3. At the end of the re-approach motion, the FC9 signal "ASUB done" is set and the path of the interrupted part
program is continued.
Note
The NC/PLC-interface signal DB21, ... DBX318.0 (ASUB is stopped) is available only for
the following case: Interrupt "interrupted" in program operation in the channel status.
Note
In case of interrupt routines that close without REPOS, the signals "Asub-Done" and
DB21, ... DBX318.0 (ASUB is stopped) occur at the same time.
