Product Description:
The RLB2-043FDB power lead is produced by Bosch Rexroth Indramat and belongs to the RLB Motor Power Cables series. As part of the Rexroth Cables product group, it forms the fixed link between a ctrlX inverter and an MS2(X) synchronous motor in motion-control installations. Its function is to conduct three-phase supply and protective conductors while maintaining flexibility for routing through cable chains and robotic axes in automated cells.
Mechanically, the cable is rated for 5,000,000 bending cycles in continuous-flex chains. The basic construction encloses four main conductors plus shielded signal cores arranged as 4x L + 4x 1.0 mm² + 2x 1.5 mm², and each power core has a cross-section of 4 mm² to limit voltage drop. During motion, curvature may tighten to a 7.5xD dynamic bending radius without risking conductor fatigue; when stationary, a 5xD static limit applies. An integrated M40 Power Connector locks to the motor housing, and the opposite end terminates directly at the drive, enabling motor-drive connection to ctrlX DRIVE cabinets without intermediate terminal blocks.
Thermally, the insulation system operates from -30 °C up to 80 °C, so the assembly can serve cold-storage conveyors and warm process zones without derating. In parked positions the cable maintains integrity at a 5xD static bend, supporting long dwell times inside energy chains. Electrical matching spans the MS2(X) servo family, ensuring correct impedance and shielding when high-frequency switching edges leave the inverter. Together these characteristics support fault-free commissioning and predictable service intervals in packaging machines, gantries, and articulated robots.
