Страница: 17 / 48

Differential quadrature output (maximum 18 V)
+5VDC power supply input
The encoder interface on the Master provides the following:
X4 quadrature decoding
Maximum 300kHz count rate
+5VDC to power the encoder
The user should choose an encoder with the appropriate number of pulses per
revolution to match the transport mechanism and speed.
4.1.8 System Calibration Target
System calibration can be used to identify the location and orientation of each sensor
with respect to a calibration target positioned in the measurement range of the sensor(s).
After successful system calibration ranges from the sensor(s) are transformed to a new,
common coordinate system.
The dimensions of the target can be configured manually, which allows for optimal
flexibility in choosing a target. There are, however, properties that affect the chance on
successful calibration. Here are some guidelines for choosing the right target shape,
size, and positioning:
Take a large
(400mm X 400mm X …mm), bar shaped object
Make sure the sensors clearly see an edge vertex, ideally a right angle. Seeing
the letter “V” when not calibrated, is ideal.
Make sure as many points as possible are visible along each side of the vertex
Avoid having objects in the FOV other than the calibration target
4.1.9 Sensors
Within a single scan sensor system various models can be used. Configurations
in which sensors are mounted opposing each other are allowed. When working with
more than one sensor the following restriction applies:
Laser lines may only intersect if the intersecting lines are from sensors in
different groups. The maximum number of groups is two.
It is possible to use different configurations of sensors within each of the two groups, and
no symmetry or alignment between groups is required.
