An important feature of servo cables is their low-capacitance and low-attenuation design as this enables them to bridge long distances without any loss of power. The two new cables are exemplary in this regard and were presented by LAPP at the SPS IPC Drives 2017 trade fair in Nuremberg.
ÖLFLEX® SERVO 7TCE: The servo cable is suitable for servo drives from many leading manufacturers and has UL TC-ER and Flexible Motor Supply listings. The internal structure is complex with a core insulation made of XLPE and an outer sheath made of a special thermoplastic elastomer. This results in a low-capacitance design which enables large distances to be bypassed between the servo controller and the motor. The cable fulfils various requirements for oil resistance, flame retardance and UV resistance, all in accordance with North American standards.
ÖLFLEX® SERVO 728 CY: The shielded encoder cable is suitable for most analogue and incremental rotary encoders in servo drives from leading manufacturers. Its core insulation made of polypropylene has low attenuation and also enables large transmission distances. The shielded cable is oil-resistant and is therefore suitable for many mechanical engineering applications with fixed installation. Nevertheless, it is still thin and light.
