Servo cable design
There are two different shields in the servo cable. One is the overall shield, which ensures that EMC behaviour towards the outside is correct. This prevents other machine components from being destroyed. The other shields the pairs for the brake and temperature sensor, ensuring that interference in the energy cores is not passed on to the frequency converter's control circuit. These shields are designed differently depending on mechanical stress. The greater the cable's mechanical stress level, the higher the quality of shielding design necessary. In practice, this means that, for our high-end cables, the shielding must have much higher mechanical coverage (up to 90%). Moreover, for the control pairs in the cable, we use a special layer that has not only good EMC properties, but also a special design that allows it to be machined very quickly.
