6.16 Head endurance run LS

6.16.1 Measurement principle

The Head endurance run LS measurement checks the reliability of the Z-axis and the DPs, espe-

cially for the standard range of components which are typically processed using the standard

placement parameter.

When the Z-axis is verified, each segment is moved up and down several times to determine the

characteristics during the upward and downward movement. Before every downward movement,

the DP is turned by 180° with the time measured it takes to reach the final position.

1 Measured Segment

2 Total number of cycles performed

3 Value for difference between Zminpick and Zmaxpick:

Zdowndeltapick = Zmaxpick – Zminpick

4 Value for difference between Zminplace and Zmaxplace:

Zdowndeltaplace = Zmaxpick – Zminplace

5 MinDPtime shows the value for the minimum time the DP needs to turn from 0° to 180°.

6 MaxDPtime shows the value for the maximum time the DP needs to turn from 180° to 0°.

7 #OK shows the number of successful Z-axis movements (50 up + 50 down).

8 #error…0 shows the number of failed Z-axis movements (up and down).

9 Result display indicating if the values are within (green tick) or outside (red cross) the lim-

its.

10 #moves shows the number of performed Z-axis movements (50 up + 50 down).

6.16.3 Interpretation of the results obtained

‘Z down delta pick’ and ‘Z down delta place’ errors for all segments

Cause Solution

Z-motor defective ► Replace the Z-motor.

Z-motor linear guide not moving smoothly ► Replace the Z-motor.

Read unit of Z-motor polluted ► Clean the read unit of the Z-motor.

Light barrier Z down dirty / defective ► Clean or replace the light barrier.

‘Z down delta pick’ and ‘Z down delta place’ errors for individual segments

Cause Solution

DP linear guide not moving smoothly ► Replace the DP unit.

Linear guide of segment not moving smoothly ► Replace the linear guide of the segment.

Anti-glare shield defective or incorrectly fitted ► Replace the anti-glare shield.

Light barrier of segment dirty or defective ► Clean the light barrier through the service

windows.

‘Min DP time’ or ‘Max DP time’ errors for individual segments

Cause Solution

Internal DP/segment problem ► Replace the segment (DP).
