The servo cable ÖLFLEX® SERVO 719 CY 4G2,5 from Lapp is a flexible control cable designed for use in industrial drive systems. It is intended for connecting frequency inverters to servo motors and is designed for moderate mechanical stress. The cable is intended for fixed installation and can be moved occasionally, provided no tensile stress occurs. It is suitable for use in dry and damp rooms. The PVC outer sheath is resistant to acids and alkalis and conditionally oil-resistant, enabling use in various industrial environments.

Applications

The cable is specifically designed for applications in the field of drive technology, particularly for connecting frequency inverters to servo motors. It is used in machine building, manufacturing technology, and automation systems where reliable signal and energy transmission is required. The construction allows use in environments with moderate mechanical stress, without the cable being subject to continuous movement or tensile stress.

Functions and features in detail

The ÖLFLEX® SERVO 719 CY 4G2,5 features a shielded design with a copper braided shield that provides high coverage. This ensures effective protection against electromagnetic interference, which can occur during signal and energy transmission in industrial environments. The cable is available in various variants, including versions without and with additional control wire pairs for functions such as brakes or temperature sensors. The control wire pairs are also shielded to maintain signal integrity.

Technology explained simply

The cable features low-capacitance core insulation, suitable for long transmission distances, as it minimizes signal distortion. The operating voltage is U0/U: 0.6/1 kV, which is sufficient for most industrial applications. In North America, an operating voltage of 1000 V is permitted according to UL, enabling use in this market. The PVC insulation and outer sheath provide good mechanical stability and chemical resistance. The cable is flexible, which facilitates installation and routing.

Compatibility and accessories

The servo cable is compatible with servo drives from well-known manufacturers, enabling universal use in various systems. The multiple certifications, including UL and CSA certification, allow use in the North American market. Certification reduces part variety and supports logistical efficiency, as the same product can be used in different regions.

Installation and mounting

The cable is designed for fixed installation and can be moved occasionally, provided no tensile stress occurs. The flexible structure facilitates routing in machines and plants. Installation is carried out according to the respective technical specifications and standards of the plant.

Advantages in operation

The combination of high interference immunity, chemical resistance, and flexible routing makes the cable a reliable solution in industrial automation. The low-capacitance insulation ensures clear signal transmission over long distances. Multiple certification enables universal use and reduces complexity in logistics. The cable is suitable for use in dry and damp rooms, expanding its range of applications.
