RLC1-011BAB by Bosch Rexroth Indramat

The RLC1-011BAB power cable is produced by Bosch Rexroth Indramat and belongs to the RLC1 Motor Power Cables series. It serves as the main power connection between compatible drive controllers and servo motors in automated machinery. The cable is built for flexible routing through drag chains and cable guides, helping keep power transmission stable on moving axes. Its layout also helps keep high-frequency interference away from nearby control wiring. That combination is useful on compact servo axes where cable movement is frequent and routing space is limited.

Four power cores, each with a conductor cross section of 0.75 mm², correspond to 18 AWG and support a continuous phase current of 10.4 A. The internal arrangement follows 4 x L + 2 x 0.14 mm², combining the main power conductors with smaller auxiliary leads for brake release or sensor supply functions. Those auxiliary conductors use stranded copper with a cross section of 0.14 mm², which helps keep the cable compact while still carrying low-level control current. The larger conductors carry motor power, while the smaller conductors support auxiliary functions without requiring a separate cable run. This structure helps limit coupling between power and auxiliary paths.

The cable is rated for 5,000,000 cycles of track motion, supporting continuous use in gantries and pick-and-place axes. When it is installed within the specified temperature range and bending radius, it can reach a service life of up to 30,000 h. It is electrically compatible with the IndraDrive family, including IndraDrive C and IndraDrive Mi regulators. This supports use with cabinet-mounted, decentralized, and motor-mounted inverter arrangements. The cable is matched for use with ML3 motors, so the pin assignment and electrical characteristics suit standard drive-to-motor connections.
