9.7.4.1 Centering with Measurement
–
The motor controller is set via the output Port A5.4 or A9.4.
–
The toothed strip support moves with the claws towards the segment. The pairs of jaws close. As soon as
both pairs of jaws have closed, the measurement triggering bero B3 is released.
–
After a short delay to avoid bounce effects the measurement procedure starts.
–
Measurement takes about 30 ms.
–
Once measurement is finished, the motor controller is reset. The toothed strip support moves towards the
rest position. The jaws then open.
–
Once the rest position is reached, the end position bero B2 is activated. The centering station is held in its
rest position by the quiescent current of approx. 200 mA.
–
After this centering procedure is completed the end signal will be given; the revolver head can cycle on.
9.7.4.2 Centering without Measuring
–
The motor controller is set via the output Port A5.4 or A9.4.

When the z jaws (ceramic jaws) touch the component, the ceramic jaws bero B1 is released
(Ports E5.5 or E9.5).
–
The motor current is increased and the h jaws (measuring jaws) close more rapidly.
–
Once the h jaws have also closed, the measurement triggering bero B3 is released (Ports E5.7 or E9.7).
–
The motor controller is reset. The toothed strip support moves towards the rest position. The jaws then

9.8 Segments
The revolver head has a total of 12 segments. The segments slide on the guide shafts of the revolver head.
Evacuation of the segment or nozzle takes place via the vacuum tube of the revolver head.
As the revolver head cycles on, the segments bring the picked-up components to the individual work stations
of the revolver head. At each work station the actions required for mounting the components will be
performed. The following revolver head stations are work stations:
At revolver head station 7 you can remove and fit segments using the segment removal tool.
