Product Description:

The Bosch Rexroth Indramat RLB2-063JEB is a motor power cable supplied in the RLB Motor Power Cables series. As a flexible link between MS2(X) servo motors and ctrlX DRIVE inverters, the assembly delivers regulated three-phase power while maintaining electromagnetic compatibility. It belongs to the Rexroth Cables product group and incorporates the manufacturer’s M58 connector on the motor side to simplify field installation within modular automation cells.

The cable is rated for 5,000,000 bending cycles, so it suits energy-chain applications with frequent axis motion. During dynamic movement the minimum bend radius is 7.5×D, limiting mechanical stress on the core strands, while static laying permits a reduced radius of 5×D. A power wire cross-section of 16 mm² keeps voltage drop low on high-current servo axes. The conductor can reach 90 °C when clamped in fixed routing without compromising insulation class, but the allowable temperature falls to 80 °C under continuous flexing to prevent premature polymer fatigue. These thermal classes align with the selected PVC jacket materials specified for the RLB line.

The Basic cable design uses standard insulation materials that remain stable up to 80 °C, matching both the maximum operating and storage limits. When equipment is idle in cold environments it tolerates ambient temperatures down to -30 °C, and the same minimum applies during warehouse storage. An M58 motor-side plug mates directly with MS2(X) stators, while the outer end is prepared for cabinet terminals on ctrlX DRIVE amplifiers, eliminating adaptation hardware. Being categorized as power cables, RLB assemblies focus exclusively on phase conductors without signal pairs, which helps achieve compact external diameters and simplifies routing in crowded energy tracks. This aids preventive maintenance planning in servo gantries.
