Position
To ensure correct functioning of the ICR890 System, the position and angle of the camera
and the deflection mirror have to be adjusted to the conveyor level.
The position of the object trigger control (photoelectric reflex switch) on the outer right-hand
edge of the conveyor system is considered the point of reference, as viewed in the direction
of transport.
The
α
and
γ
angles must be set depending on the position of the System (e. g. on top or at
the side). In order to prevent direct reflectance, the light must be incident at an angle of
approx. 15
°
(
β
= skew) on the object surface against the direction of transport.
The position and the angle of the camera and the deflection mirror can be configured using
the SOPAS-ET Configuration Software:

Increment configuration
In order to control the camera line frequency, the ICR890 System requires information on
the conveyor speed. An external
incremental encoder
delivers pulses which are used to
determine the current conveyor speed.
The conveyor speed results from the number of pulses and the resolution of the external
incremental encoder.
The increment source and resolution/speed can be configured using the SOPAS-ET
Configuration Software:
