If the order does not include a controller, the UNITRONIC® LiYCY (TP) cable will be compressed
to RJ-45 Ethernet and two power wires (red and brown).
5.4.2. RJ-45 Ethernet cable
The RJ-45 Ethernet cable is used to connect the scanner controller to the robot
controller.
5.4.3. Power cable
The power cable is used to connect the scanner controller to 220V AC.
5.5. Calibration plate
The calibration plate is used to calibrate the scanner relative to the welding robot.
The calibration procedure is described in par. 15.6.8.
6. Operating principle
The laser scanner is mounted on the flange of the robot next to the welding torch.
The scanning area is located directly in front of the welding electrode at a distance of
several centimeters. The scanner controller processes the information received from the
scanner in accordance with the selected mathematical algorithm that determines the exact
coordinates of the welding joint. In real time, the scanner controller transmits the coordinates
to the robot controller, and the robot controller corrects the position of the welding torch
during the welding process.
