Figure 2-6 REPOS sequence in part program with timed acknowledgement signals from NCK
NCK sets acknowledgement again
Phase with REPOSPATHMODE still active (residual block of the program stopped at → Time
(2) is not yet completely executed).
As soon as the REPOS repositioning motion of the ASUB is executed, the NCK sets the
"Repos Path Mode Ackn" again (→ Time (5)). If no REPOSPATHMODE has been
preselected via a VDI signal, the programmed REPOS mode is displayed.
"Repos Path Mode Ackn" is canceled when the residual block is activated (→ Time (6)).
The part program block N30 following the block at → Time (2) is resumed.
The interface signal:
DB31, ... DBX70.2 (Repos Delay Ackn) is defined in the same way.
DB 31, ... DBX70.1 (Repos offset valid) = 1, if:
DB21, ... DBX319.1-319.3 (Repos Path Mode Ackn0 to 2) = 4 (RMN).
