SICK CLV63x User Manual

The switching of the focus is carried out by the changing object distance (e.g. during
reading from the top: object height detection).
Trigger sources for switching are:
– Signal on switching input “Sensor 2” for the max. 2-level switching
– Command to the host interface or the integrated timer (e.g. for search run) for the
max. 8-level switching
– Oscillating mirror turning points for deflection on both sides in the case of the line
scanner with oscillating mirror
The distance configurations are assigned to the switching order via a programmable
assignment table.
NOTE
The SOPAS-ET configuration software can be used to configure the focus position:
•
Project tree, CLV6xx, parameters, read configuration

3.2.3.4 Oscillating mirror control
In the case of a line scanner with oscillating mirror, the position of the scan line is influ‐
enced by the configuration of the oscillating mirror.
In addition to the “Park” (fixed, adjustable position of the scan line) or the continuous
oscillation (irrespective of the read cycle), optimized function processes related to the
read cycle are also possible in the controlled operation of oscillating mirror:
– n-times oscillation around an adjustable start position within the read cycle
– One-Shot: single deflection (approach and return) per read cycle from an adjusta‐
ble start position
In each oscillation mode, the deflection width can be set (amplitude) independently for
each of the deflection directions. Within the selected cycle duration of the entire vibra‐
tion process, the deflection speeds can be set in relation to each other for both deflec‐
tion directions.
