Delayed approach of axis with REPOS offset
Using the axial, level-triggered axis/spindle VDI signal (PLC→NCK):
DB31, ... DBX10.0 (REPOSDELAY)
the REPOS offset for the axis is only applied with the edge of
DB21, ... DBX31.4 (REPOSMODEEDGE)
at its next programmed instance.
Whether this axis is currently subject to a REPOS offset can be scanned via synchronized
actions with $AA_REPOS_DELAY.
Caution
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 VDI signals
The 0/1 edge of the channel-specific VDI-Signal (PLC→NCK):
DB21, ... DBX31.4 (REPOSMODEEDGE)
is used to transfer the level signals from:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0-2)
and
DB31, ... DBX10.0 (REPOSDELAY)
to the NC.
The levels relate to the current block in the main run. There are two different cases:
Case A:
One repositioning block of a currently active REPOS operation is contained in the main run.
The active REPOS operation is aborted and restarted, and the REPOS offsets are controlled
via signals:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0-2)
and
DB31, ... DBX10.0 (REPOSDELAY).
Case B:
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:
DB21, ... DBX31.0-31.2 (REPOSPATHMODE0-2)
and
DB31, ... DBX10.0 (REPOSDELAY).
