●
Click on the
Calibrate RV head
button.
The calibration will be performed in the following sequence:
–
calibration of the RV camera
–
determination of segment offset
I
for all 12 or 6 segments
–
determination of segment offset
II
for all 12 or 6 segments
Segment offsets
II
are determined with the z-axis extended. The measurement is performed
repeatedly for each segment. The average value is calculated for each segment from the
measured values determined. The RV-PCB camera offset refers to segment
I
.
●
If you wish to determine segment offset
I
or
II
for a particular segment, first click on the
Step star axis
button repeatedly until the number of the desired segment (center sleeve) is displayed in the bottom
position.
●
Click on the
Calibrate segment offset I individ.
or
Calibrate segment offset II individ.
button.
The respective segment offset will be determined for the selected segment.
NOTE
The functions “Calibrate segment offset
I
individ.” and “Calibrate segment offset
II
individ.”
are only intended for error analysis purposes if the calibration of the RV head could not be carried out
successfully.
After the determination of individual segment offsets, the RV head must be completely recalibrated.
NOTE
After the completion of the calibration procedure it is possible to display the values determined during
the calibration of the RV camera by means of the
Display camera coefficient...
function.
The values determined for the segment offsets can be displayed using the
Display segment offset I
of all segments...
or
Display segment offset II of all segments...
, respectively.

3.5 Calibration of the Machine Zero Point
NOTE
Verify that the calibration data for the RV camera, segment offset
II
(RV-PCB camera offset) and PCB camera
have already been determined.
On SIPLACE 80S machine types, the calibration of the machine zero point must be performed for both gan-
tries directly one after the other!
The MA zero point (measuring hole) is integrated on the fixed conveyor side in the same segment as the cali-
bration tool pocket (see Fig. 3.12.1 in section 3.12). This applies to all conveyor types!
●
In the main view click on the icon or or to switch the screen display to the "Gantry"
display (see Fig. 0.3.4) of the desired gantry.
●
Click on the icon to switch to the "Calibrate positions" display.

●
Click on the
Approach
button in the "Machine zero point" field.
The active gantry moves the PCB camera over the measuring hole for the MA zero point.
The screen display is switched to the PCB camera.
●
Check whether the measuring hole for the machine zero point is visible in the camera’s field of view.
●
Press
ESC
to return the screen display to the normal program mode.
●
Click on the
Calibrate
button in the "Machine zero point" field.
The calibration of the machine zero point will now be performed. The position values for x and y are
displayed in the "Machine zero point" field.
