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 group.
This signal shows the status of the current block to be executed during block change.
Subsequent status changes are ignored.
Once the SERUPRO operation is ended with "Search target found", the IS
DB31, ... DBX76.4 (path axis) is relative to the target block.
2.6.1.2 Repositioning on contour with controlled REPOS
Approach modes
Influence path axes individually
During SERUPRO approach, a REPOS operation is initiated in order to reposition to the
contour. A large number of axes, which the user can control by means of interface signals, is
frequently moved. The operator panel interface supplies the offsets per channel axis, which
REPOS intends to traverse.
Repositioning of the individual path axes can be controlled by the PLC with the interface
signals and it therefore has priority over the actual commands
