Measuring system cable for the energy chain

A measuring system cable can usually be found on every drive unit and is bright green in colour. This colour originates from the DESINA and is now also established outside the machine tool. It is used for signal feedback from the encoder system to the frequency inverter and is sometimes called the tacho cable or encoder cable. It contains many data wires for signal transmission. The various signals generated by the encoder represent the exact movement of the motor and are transmitted with it. As a rule, however, the cable not only transports the data of the encoder system, but also supplies the encoder.

Design differences according to manufacturer
There are various manufacturers of measuring systems on the market. The differences between the suppliers are also reflected in the cable construction, where we are electrically identical. The wire cross-section combinations, the core identification and also the element shield differ significantly depending on the manufacturer. At igus®, we match the important elements such as outer jacket, shield, inner jacket and many more to the movement in the energy chain. This enables us to achieve optimum durability.

DriveCliq - the standard from Siemens
DriveCliq is a digital encoder interface from Siemens. The standard is now openly accessible and can also be used by other manufacturers. In contrast to the usual encoders of earlier generations, this encoder system is equipped with a CAT5 Ethernet element and two stronger supply wires. As a rule, a connector solution from Yamaichi is used for the connection, which carries the data in a similar way to an RJ45 connector, but also accommodates the power contacts to the right and left of the notch. This connector face is located in an IP20 housing for the control cabinet or an IP65 housing for the field. In the meantime, an M12 solution is also gaining acceptance among connectors because it is more robust and compact and also eliminates the need for a connection coupler, which is very expensive.

DriveCliq - the standard for the machine tool
A few years ago, there was a major changeover from conventional analogue encoder systems to the then new DriveCliq technology. Here we were able to provide support with the implementation for major customers such as WALDRICH from Coburg. The challenges arose with the new connector technology in conjunction with long cable lengths. Together, we developed a solution for the extremely robust M23 circular signal connector, which was significantly superior to the original solution in terms of processability and data transmission. So if you are also looking for a solution that is not available in the catalogue today, come to us and we promise to take a close look at your application.

inner jacket - why important on long travels and small radii
The inner jacket between the core structure and the wing is a unique construction detail in our high-end cables. It protects and guides the sensitive core and supports the glider. This is both extremely important, both in long travels and in small bend radiuses. This is where the most extreme forces act on the cable.
