RL2-066GBB by Bosch Rexroth Indramat

The RL2-066GBB motor power cable is manufactured by Bosch Rexroth Indramat as part of the RL2 Motor Power Cables series. In automated assembly lines or packaging stations, the cable supplies regulated AC power from a drive controller to a servomotor so that axes run with synchronized speed and torque. It serves as the link between the drive output and the motor input during repeated acceleration, deceleration, and direction changes. Its assignment to the Rexroth Cable product group indicates standardized connectors and sheath materials matched to the motion platform, while the design targets second-generation motors that require reduced installation space and high dynamic motion.

The RL2-066GBB is rated for 5,000,000 bending cycles, so it can operate inside energy chains without early conductor fatigue. A dynamic bending radius of 7.5 × D is the smallest loop it may use while the axis is moving, whereas a static bending radius of 5 × D applies to fixed routing in the control cabinet. Its cross-sectional area of 6.0 mm² allows the four power conductors to carry the continuous phase current used by medium-frame servomotors without excessive voltage drop. The M58 screw-lock motor connector creates a vibration-resistant mechanical interface that eliminates the need for field crimping. The cable uses the basic design variant, which uses standard PVC insulation and a compact outer diameter.

Inside the sheath, the conductor layout follows 4 x L + 4 x 0.75 mm², pairing four power cores with four smaller auxiliary wires for encoder shielding or brake-release signals. This arrangement supports power transmission and related control functions in one cable body, which helps reduce routing space around moving axes. The topology mates directly with IndraDrive power modules and matching MS2x Plug A/B motor sockets, eliminating adapter harnesses. Because the assembly supports a direct motor-drive connection, impedance remains predictable and electromagnetic emissions stay within drive system limits.
