RL2-500CBB by Bosch Rexroth Indramat

The RL2-500CBB is a motor power cable produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. Classified as a power-supply lead, it links control-cabinet drives to servo motors while transmitting phase and earth conductors and remaining flexible enough for dynamic machine axes. In industrial automation, it provides a predefined, factory-terminated connection that reduces wiring time and ensures electrical compatibility with Rexroth motion systems. Its basic cable design keeps the diameter and weight moderate, which supports integration in tight drag-chain layouts.

Mechanical life is rated for 5 million bending cycles, indicating how often the sheath can flex before fatigue risks increase. During motion, the cable requires a dynamic loop radius of 7.5xD; this minimum arc helps prevent conductor stress when the cable is carried in energy chains. For static routing inside panels, the permitted bend radius is 5xD, reflecting the lower mechanical demand of fixed installation. The power conductors are arranged as 4x L + 4x 0.75 mm², combining four main phases with four smaller auxiliary cores for ground or sensing lines. Each main core has a copper cross-section of 1.0 mm², so voltage drop stays within drive tolerances on moderate cable lengths.

The motor end uses a factory-crimped M17 power connector, matching the locking thread and pin layout of second-generation motors. On the controller side, the cable mates with IndraDrive units, allowing immediate power distribution without additional adapters. Compatibility is limited to MS2x with Plug D machines, so the shielding arrangement matches that platform correctly. The lead is supplied as an extension cable, so it bridges between an existing motor pigtail and the drive cabinet when the standard length is insufficient. The outer jacket is oil-resistant and supports continuous motion on second-generation axes.
