Repositioning to the contour (REPOS)

The "Reposition to the contour" (REPOS) function can be used to continue an interrupted
machining at the interrupted location. Unlike REPOS, SERUPRO permits the "refetching" or
"repetition" of a program section. For this purpose, once SERUPRO has found the target block,
the contour is positioned at the location selected as REPOS mode and the machining
continued.
SERUPRO: Set REPOS response
The REPOS behavior, i.e. the behavior in the repositioning block, is set with the following
machine data :
MD11470 $MN_REPOS_MODE_MASK = <REPOS mode>
MD11470 $MN_REPOS_MODE_MASK
Bit Value Meaning
0 0 An interrupted delay time is repeated
1 An interrupted delay time is continued
1 - Reserved
2 0 DB31, ... DBX10.0 (REPOSDELAY) not considered in the repositioning block.
1 DB31, ... DBX10.0 (REPOSDELAY) considered in the repositioning block.
3 0 SERUPRO: Only path axes traverse in the repositioning block
1 SERUPRO: Path and positioning axes traverse concurrently in the repositioning block
4 0 REPOS : Only path axes traverse in the repositioning block
1 REPOS : Path and positioning axes traverse concurrently in the repositioning block
5 0 During the interruption, changed feedrates and spindle speeds act only after the first part program block
following the interruption location
1 During the interruption, changed feedrates and spindle speeds act following the interruption location
6 0 SERUPRO: In the repositioning block, neutral axes and positioning spindles traverse as path axes.
1 SERUPRO: In the repositioning block, neutral axes and positioning spindles traverse as command axes.

The level of interface signal:
DB31, ... DBX10.0 (REPOSDELAY)
is read if REPOSA is interpreted.
Axes, which are neither geometry nor orientation axes, are then excluded by REPOS and are not moved.
Risk of collision
MD11470 $MN_REPOS_MODE_MASK, Bit 3 or Bit 4 = 1
The user alone is responsible for ensuring that the concurrent traversal of the axes in the
repositioning block does not cause any collision on the machine.
