9.8 Block search Type 5 (SERUPRO)
Whether this axis is currently subject to a REPOS offset can be scanned via synchronized
actions with $AA_REPOS_DELAY.
Risk of collision
Interface signal:
DB31, ... DBX10.0 (REPOSDELAY)
has no effect on machine axes that form a path.
Whether an axis is a path axis can be determined with:
DB31, ... DBX76.4 (path axis).
Acceptance timing of REPOS NC/PLC interface signals
With the 0/1 edge of the channel-specific NC/PLC interface signal (PLC→NCK):
DB21, ... DBX31.4 (REPOSMODEEDGE)
the level signals of:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2)
and
DB31, ... DBX10.0 (REPOSDELAY)
are transferred to the NC.
The levels relate to the current block in the main run. There are two different cases:
1. One repositioning block of a currently active REPOS operation is contained in the main run.
The active REPOS operation is aborted, restarted and the REPOS offsets controlled via
the signals:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2)
and
DB31, ... DBX10.0 (REPOSDELAY).
2. No repositioning block of a currently active REPOS operation is contained in the main run.
Each future REPOS operation wishing to reapproach the current main program block is
controlled by the level of interface signal:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0 to 2)
and
DB31, ... DBX10.0 (REPOSDELAY).
