WCS and PCV Position Feedback
Systems
The PosiTrack WCS system from Pepperl+Fuchs brings fraction-of-a-
millimeter position feedback to a wide range of industrial and commercial
applications. Overhead monorails, gantry cranes, automated warehouses,
even elevators and theater stage lighting systems can raise their
performance to new levels with PosiTrack.
WCS position feedback system
Automating material handling systems requires information about the
moving vehicle or forklift truck that is accurate to the millimeter. The WCS
position feedback system provides the operator with a reliable and proven
positioning system. It combines two important characteristics: noncontact
technology and absolute positioning. You need just two components for
positioning within your application—the read head and the code rail.
The read head
The U-shaped read head optically scans a uniquely coded rail that enables
the position encoding system to detect a new position value every 0.8 mm.
Position values are determined regardless of temperature fluctuations and
in real time, even at high travel speeds. The read head’s sophisticated
intelligence provides rock-solid data in some of the toughest conditions.
If the high-powered optics lose strength, the read head provides a
maintenance control signal well before the system’s output is influenced.
All read headscome with a snap-on mounting bracket and field-attachable
connector.
The data is transferred directly from the read head to the control unit via
a serial RS485, SSI, or CANopen interface. A wide range of interface
modules are available for connecting to bus systems, such as PROFIBUS
DP, PROFINET RT, MODBUS/RTU, DeviceNet, or EtherNet/IP.
The code rail
Availableinstainlesssteelorfiber-laminate,thecoderailispositionedparallel
to the travel path and assigns a clear and exactly reproducible position at
each point of the travel path. All rail types can be hirozontally curved with no
affect on the read head’s accuracy. Fiber-laminate rails can alco be flexed
for vertical bends. Brackets are available for quickly mounting the code rail.

PCV Data Matrix position feedback system
The PosiTrack PCV Data Matrix position feedback system scans a custom
data matrix-marked tape using 2-D camera technology. Continuous
feedback to distances of six miles is possible with accuracy to ±0.1 mm.
The data bits of the Data Matrix code are divided into two dimensions and
provide a high degree of data density over a small surface area.
The PCV read head and the Data Matrix code tape are suitable for a wide
range of positioning tasks. The code tape is available in lengths up to
10 km. Several Data Matrix code sections can also be used to evaluate
vertical position.

Application examples
Monorail conveyor
The Data Matrix code tape is affixed directly above the power rails and the
PCV read head attached to the hanger. Each hanger is optimally positioned.
Skid conveyor
The simple attachment of the self-adhesive code tape together with its
chemically resistant coating mean the PCV system is ideal for positioning
skids.
High-bay warehouse
The PosiTrack PCV positioning system is always the best choice for moving
and positioning in an X or Y-direction.
