Product Description:

The RLB2-011CBB belongs to the RLB Motor Power Cables series produced by Bosch Rexroth Indramat. It functions as a dedicated power link between an MS2 synchronous servo motor and its matching drive in automated machinery, carrying mains power and auxiliary signals in a single flexible jacket to streamline cabinet-to-machine wiring.

This cable follows a Basic design that groups four power conductors, each with a cross-section of 1.0 mm², alongside auxiliary conductors rated at 4 × 0.75 mm² for feedback-related circuitry. A robust SPEEDCON locking system couples the drive end, while the motor side terminates with an M17 circular connector, enabling tool-free assembly and reliable shielding continuity. The construction tolerates up to 5 million bending cycles, so it can operate inside continuously moving cable tracks without early fatigue. Cabling is specified as 4 × L + 4 × 0.75 mm², and the overall layout keeps the motor-drive connection direct to minimise voltage drop and simplify installation within Rexroth Cables product group power-cable routing schemes.

A dynamic bending radius of 7.5×D governs routing inside energy chains, while a fixed routing can adopt a tighter static radius of 5×D when the machine is at rest. The assembly is approved for the ctrlX DRIVE control platform, ensuring EMC compatibility and length-matched impedance when paired with the associated inverters. It also matches the electrical pin-outs and insulation requirements of the MS2(X) motor series, providing uniform wiring practice across multiple frame sizes. These mechanical limits and interface matches allow the cable to supply stable current, maintain shielding integrity, and support predictable service intervals in multi-axis production cells.
