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 (path axis) refers to the target block.
9.8.1.2
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

RMI
Repositioning to interruption point
RMB
