3.1 Communication
All exchange of information between the welding equipment and the robot system
takes place via a CAN--bus. The welding data unit in the welding power source
handles this communication.
3.2 Equipment
The MigRob 500 power source is supplied with 2 terminating resistors, a 5 m return
cable and an instruction manual.
Note! One terminating resistor for the internal bus and one for the external bus.
