4.11.2 Explanation of Measurement Results in "Progress" Menu
After completion of the measurement, the following results appear in the "Progress" menu:

Figure 42: DP-Z positioning_2 result
Legend:
1. Segment measured
2. Value determined Z Variation [µm] This value is calculated by finding the difference
between the minimum and maximum Measure 1 – Measure 6 value (end position signal Z-
down light barrier).
Z Variation [µm] = Maximum Measure 1-6 [µm] value – Minimum Measure 1-6 [µm] value
The Z Variation [µm] value shows the Z-down light barrier end position signal variance in
accordance with the rotary angle of the segment.
The "Z Variation [µm]" value must be within a plausible tolerance (in our case 0..75µm).
If the value is outside this tolerance, it is not possible to guarantee accurate placement at
every angle.
3. Value determined CS Variation [µm] This value is calculated by finding the difference
between the minimum and maximum CS pos 1 – CS pos 6 value (interruption of component
sensor).
CS Variation [µm] = Maximum CS pos 1-6 [µm] value – Minimum CS pos 1-6 [µm] value

The CS Variation [µm] value shows the component sensor CS pos 1-6 variance in
accordance with the rotary angle of the segment.
The "CS Variation [µm]" value must be within a plausible tolerance (in our case 0..25µm).
If the value is outside this tolerance, it is not possible to guarantee accurate placement at
every angle.

5. The values Measure 1 [µm] – Measure 6 [µm] are as follows:
Rotary angle 0° Light barrier Z-down measure 1 [µm]
Rotary angle 60° Light barrier Z-down measure 2 [µm]
Rotary angle 120° Light barrier Z-down measure 3 [µm]
Rotary angle 180° Light barrier Z-down measure 4 [µm]
Rotary angle 240° Light barrier Z-down measure 5 [µm]
Rotary angle 300° Light barrier Z-down measure 6 [µm]
6. The values CS pos 1 [µm] – CS pos 6 [µm] are as follows:
Rotary angle 0° Component sensor value CS pos 1 [µm]
Rotary angle 60° Component sensor value CS pos 2 [µm]
Rotary angle 120° Component sensor value CS pos 3 [µm]
Rotary angle 180° Component sensor value CS pos 4 [µm]
Rotary angle 240° Component sensor value CS pos 5 [µm]
Rotary angle 300° Component sensor value CS pos 6 [µm]
7. This diagram illustrates the "Variation [µm] (2)" values for the segments.

8. This diagram illustrates the "Measure1" – "Measure6" values for the segments.
Blue bar one bar each for "Measure1(0°)" – "Measure6 (300°)"
If the Z-down light barrier is working reliably, the bars should
ideally be the same height or have little variance to the other
segments.
9. This diagram illustrates the "CS pos 1" – "CS pos 6" values for the segments.
Green bar one bar each for "Measure1(0°)" – "Measure6 (300°)"
If the component sensor is working reliably, the bars should ideally
be the same height or have little variance to the other segments.

4.11.3 Explanation of Measurement Results Using Results PDF
These results can be seen if you scroll down the "Summary" menu or generate a results PDF!
Figure 43: Results PDF DP-Z positioning_1
Figure 44: Results PDF DP-Z positioning_2
You can see that, in the case of segment 1 (1) and also segment 11 (2), the component sensor CS
pos 4 [µm] switches earlier at an angle of 180°. This is shown in the green bar chart.
This low value also means that the "CS Variation [µm]" value is outside the permitted tolerance.
Reliable placement of the entire DP positioning area can therefore not be guaranteed.
