Product Description:

The RL2-066GBB is a motor power cable produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. Classified in the Rexroth Cable product group, this assembly links servo drives to synchronous motors in automated lines. By carrying three-phase power and auxiliary conductors in a single sheath, the cable enables direct energy transfer and feedback reference between cabinet-mounted converters and moving axes, reducing panel space and simplifying machine routing.

Mechanical construction follows the Basic design, meaning the sheath, shielding, and filler materials conform to the standard endurance level for this series. The cable type is noted as 4x L + 4x 0.75 mm², and the identical conductor configuration ensures the four power phases and four smaller signal cores are laid concentrically. Each power core features a cross-section of 6.0 mm², supporting the current required by mid-frame IndraDrive inverters. Flex applications are accommodated by a dynamic bending radius of 7.5xD, while static installation can tighten to 5xD without damaging insulation. The PUR jacket and fine-strand copper achieve a lifetime rating of 5,000,000 bending cycles, making the assembly suitable for continuously moving cable chains. A direct motor-drive connection further removes terminal boxes and minimizes voltage drop.

System integration focuses on electrical compatibility. The cable attaches to IndraDrive power modules and terminates at second-generation MS2 motors equipped with MS2x Plug A/B coding. An M58 metal connector is pre-moulded on the motor end, ensuring shield continuity and rapid field replacement. Because the motor generation is specified as 2nd, the conductor layout aligns with the stator temperature sensor and brake wiring used in current Rexroth axes, so no pin reassignment is required. After routing, installers simply secure the jacket to the energy chain, allowing predictable EMC performance and consistent machine builds.
