Product Description:
The RLB2-022DBB is a power cable produced by Bosch Rexroth Indramat within the RLB Motor Power Cables series. It serves as the primary conductor set between an inverter and a synchronous servo motor in factory automation, delivering three-phase power as well as protective earth. The assembly is intended for continuous motion inside energy-chain carriers, and its over-moulded connector terminations shorten installation time while preserving electromagnetic compatibility in multi-axis cabinets.
The cable belongs to the Power Cables class, which means it carries motor supply conductors rather than feedback or brake cores. A copper cross-section of 1.5 mm² defines the permissible continuous current and keeps voltage drop within drive limits across typical axis lengths. During dynamic routing, the jacket endures a minimum bend radius of 7.5xD while in motion, and its flex-life rating reaches 5 million bending cycles, allowing continuous operation in energy-chain applications. The motor connector is the keyed M23 plug, so shielding and phase allocation match the Rexroth MS2 platform.
During installation, a smaller stationary loop may be applied because the static bend radius is 5xD, preventing conductor fatigue when the cable is clamped. Connection to the drive is Direct, eliminating intermediate terminal boards and simplifying maintenance. Compatibility with ctrlX DRIVE controllers and the MS2(X) motor family makes the assembly a drop-in component for new or retrofitted axes. The cable is supplied in the Basic design variant, and it is catalogued under the Rexroth Cables product group, ensuring that sheath material, conductor insulation, and EMC measures remain consistent with other motion-system harnesses in the series.
