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

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.

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.

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.
