Product description
3.4.1
Object trigger control
The ID sensors need a suitable signal (trigger) to start an object-related read process.
As standard, the start signal is issued via an external read cycle sensor (photoelectric
sensor). As soon as an object has passed the read cycle sensor, an “internal reading
interval” is opened for the reading process. The signal is distributed to the ID sensors
via the MSC800.
Alternatively, a command triggers the read process via a data interface or the
CAN-SENSOR network.
The trigger source can be configured with the SOPAS-ET configuration software:

Focus control
For dynamic focusing (focus control), the ICR890 system needs continuous information
about the distance to the object surface. In the case of reading from above, this data is
supplied by a lateral MLG light grid. During reading from the side, the dimensions of the
object are recorded by the VMS4xx/5xx volume measurement system and processed via
the MSC800.
The SOPAS-ET configuration software can be used, among other things, to configure the
default focus position and the source of the distance measurement:

Increment configuration
The ID sensors need information about the conveyor speed in order to control the tracking
information. An external incremental encoder provides pulses, from which the current
conveyor speed is determined.
The conveyor speed is derived from the number of pulses and the resolution of the
external incremental encoder.
The SOPAS-ET configuration software can be used to configure the increment source and
the resolution/speed:
