Displaying the range of validity
The range of validity of the REPOS offset is indicated with interface signal:
DB31, ... DBX70 (REPOS offset valid)
It is indicated whether the REPOS offset calculation was valid or invalid:
Value 0:
Value 1:
REPOS offset after an axis replacement
The group signal:
DB21, ... DBX319.5 (Repos DEFERRAL Chan)
can be used to determine whether a valid REPOS offset has taken place:
Value 0:
Value 1:
REPOS offset with synchronized synchronous spindle coupling
When repositioning with SERUPRO, processing continues at the point of interruption. If a
synchronous spindle coupling was already synchronized, there is no REPOS offset of the
following spindle and no synchronization path is present. The synchronization signals remain
set.
Search target found on block change
The axial VDI signal:
DB31, ... DBX76.4 (path axis)
is 1 if the axis is part of the path grouping.
This signal shows the status of the current block to be executed during block change.
Subsequent status changes are ignored.
If the SERUPRO operation is ended with "Search target found",
DB31, ... DBX76.4 refers to the target block.

The REPOS offset of this axis is calculated correctly.
The REPOS offset of this axis cannot be calculated, as the REPOS has not yet
occurred, e.g., it is at the end of the ASUB, or no REPOS is active.
All axes currently controlled by this channel have either no REPOS offset or their
REPOS offsets are invalid.
Miscellaneous.
