Product Description:
The RKL4516 motor power cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Designed for servo-drive installations, it carries three-phase power alongside auxiliary control signals, allowing a single routed bundle between the cabinet and the motor. In automated gantries, pick-and-place axes, and other moving equipment this arrangement shortens wiring runs and maintains signal integrity under constant dynamic motion.
The cable is qualified for 5 million bending cycles, so it remains functional in high-frequency drag-chain service. When secured, a minimum radius of 5 x D prevents compression of insulation layers; during flexing travel, the radius must widen to 7.5 x D to limit tensile stress on shields and fillers. Power conductors sized at 10.0 mm² deliver the full phase current, while two shielded twisted-pair bundles carry brake or encoder lines. Altogether the assembly contains 12 conductors arranged in the construction code 4×10 mm² + 2×(2×1.0)StC + 2×(2×1.5)StC, providing balanced capacity for energy and feedback functions.
Electrical losses remain low, with loop resistance at 20 °C measured at 1.91 Ω/km, keeping voltage drop acceptable on long machine axes. The insulation system is rated for 600 VAC, matching common supply voltages used by Rexroth and third-party inverters. A circular sheath of 22.2 mm fits standard cable-track separators, and the outer jacket is formed from PUR that is adhesion-free and matte so the bundle slides smoothly without sticking. Its RAL 2003 orange coloring maintains visibility in densely wired cabinets, while individual control pairs of 1.0 mm² and 1.5 mm² cross-section keep logic and brake circuits electrically distinct.
