Robot cable for the seventh axis

What exactly is the "seventh axis cable"? This cable is used on a robot when it is assembled on a linear axis. The usual multi-dimensionally moving robot has six axes to realise its motion sequence for the application. The counting sequence is, so to speak, from the robot foot starting with axis 1 to axis 6 on the "hand" of the robot. Robot cables are used at these axes due to the torsional movement. If the robot now has to travel along a production line because its work process takes longer than the cycle time available to it at its location, it is assembled on a linear axis. This axis is called the 7th axis and can be many metres long. Of course, the robot must be supplied with power and signals. In addition, the data must also be fed back to the control system. The robot needs an extension cable, so to speak, which is permanently attached to the required linear chain. This cable is known as the seventh axis cable and has a very complex structure because many different signals have to be routed.

Cables for ABB, KUKA, and Fanuc

Each robot manufacturer uses different core/cross-section combinations depending on the robot. These combinations are determined by the respective drive and measuring system of the robot. For example, a FANUC robot must of course be supplied completely differently to a KUKA robot or one from ABB. Even within the respective manufacturers, the robots use different cable constructions depending on their design. In the CFSPECIAL.792 series, we have mapped the common designs. This enables customised use even for small quantities. As the robot is generally plugged in, we can supply the cable harnessed in the desired length. Simply tell us the robot type in question and we will offer you a ready-to-plug-in solution.
