Product Description:
The RKL4529 motor power cable is produced by Bosch Rexroth Indramat for the RKL Motor Power Cables series. It is intended to connect servo drives to motors inside automated machinery where continuous motion and stringent electrical performance are required. The cable carries three-phase power, protective earth, and auxiliary control signals, providing a mechanically protected link between drive cabinets and moving axes on handling robots, gantries, and machining centers.
Its power circuit is built around 16.0 mm² copper cores arranged as 3 + PE, providing ample cross-sectional area for medium-current servo outputs while maintaining a manageable temperature rise. The loop resistance of these conductors is limited to 1.21 Ω/km, which minimizes voltage drop over long carrier runs. An outer diameter of 25.5 mm permits routing through standard energy-chain separators. The PUR sheath is matte, adhesion-free, and colored RAL 2003 orange, allowing it to slide without sticking to adjacent cables. Mechanical endurance reaches 5 million flex cycles, and the product is approved for drag-chain use, allowing it to follow linear or multi-axis tracks without premature conductor fatigue.
For feedback signals or temperature sensors, the cable provides a separate control pair with a cross-sectional area of 1.5 mm². Charge accumulation over long cable lengths is kept low by a mutual capacitance of 1.2 nF/m, helping the drive maintain precise pulse-width modulation. During dynamic operation, the cable requires a minimum bend radius of 7.5 × D. In stationary installations, the minimum bend radius is 5 × D. Following these limits preserves shielding integrity and avoids stress marks on the PUR jacket. With a mass of 1.140 kg/m, the assembly places a predictable load on drag-chain slides while remaining suitable for high-speed axes.
