Transfer of speed and increment data
•
The feed speed of the conveyor belt is detected by the photoelectric sensor array like
a measuring wheel encoder.
•
To that end, the SIM2000-2 Prime controller determines the times at which the
photoelectric sensors were passed when a transport unit passes through.
•
The speed of the transport unit can be calculated together with the parameterized
distances between the individual photoelectric sensors.
•
These speed values are then used to calculate the increment required to determine the
object’s position on the conveying equipment (referred to as “tracking”).
