Product description
4.6.4
Switchable focus position
As an alternative to the autofocus function, the focus position of the CLV65x can be chan-
ged dynamically thus covering a wide reading area.
You can define up to 8 reading areas for the distance configuration which can be started in
any order by the lens in reading operation.
Fig. 4-5:
Switching the focus for CLV65x: Division of the entire reading area in distance
configurations
The focus is shifted by changing the object position (e. g. when reading downwards: detec-
tion of object height).
Trigger sources for the switch-over are:
•
Signal at the switching input "Sensor 2" for max. 2-pole switching
•
Command from the host interface or the integrated timer (e.g. search run) for the max.
8-pole switch-over
•
Reversal points of oscillation mirror for the bilateral deflection on the line scanner with
oscillating mirror (see
chapter 4.6.5 Oscillating mirror control, page 33
)
The distance configurations of the switching order are assigned via the programmable
cross-reference list.
Note
The focus position can be configured using the SOPAS-ET configuration software:
