After reaching the requested position, confirm with [●].
w
The position of the left marking line is set.
The selected section is detected again (new profile).
Red line indicated in the display: represents the section covered by the laser line.
White marking: represents the fixed marking line.
Green arrow: represents the marking line to be moved. Two vertical ROI markings projected in
green support the setting.
The standard setting for the ROI includes the entire operating range. If the markings are not
moved, but confirmed, the entire profile taught is used for assessment.
8.1.4 Set the position of the reference profile
In the previous step, a reference profile was taught from the ROI. In the next step, you can define the
section in which the measured height profile is to be searched. There are two options:
Fixed:
The reference profile is searched in the ROI defined during teaching. As during teaching, the objects
to be monitored must be positioned very exactly during operation.
Floating:
However, due to mechanical or manual shifting tolerances it is not always possible to position the
object to be monitored correctly.
With the option [Floating], this problem can be avoided. The taught reference profile is searched
across the entire detected height profile. The taught reference profile can be successfully detected
along the X and Z axis despite a change in position.
Marking function:
During teaching, the ROI is indicated via two vertical marking lines projected in green (ROI markings).
This way, the user can see what section of the laser line is defined as ROI. After teaching has been
finished, the marking lines disappear. However, they can be displayed manually. Parameter level

In the next step, the position of the ROI is defined.
w
The options [Fixed], [Floating] and [Back] are displayed.
u
Select [Fixed], [Floating] or [Back] using [▲] / [▼] and press [●].
•
[Fixed]: No shift of the object is permitted.
•
[Floating]: A shift of the object in X direction (along the laser line) and in Z direction is permitted.
•
[Back]: Jump back to. Set ROI (
19).
