Product Description:
The RKL4563 is a motor power cable produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It links IndraDrive controllers to synchronous servo motors, delivering three-phase power and auxiliary signals in automated machinery. By integrating power and control conductors within a single sheath, the cable simplifies cabinet layouts and maintains electromagnetic compatibility in dynamic axes. Its mechanical design also supports installation in energy-chain systems where constant motion is expected.
The cable diameter measures 22.2 mm, a dimension that determines gland size and minimum bend radius. Four power cores with a combined layout of 4 × 10.0 mm² carry motor phase current while minimizing voltage drop over extended runs. A distributed capacitance of 1.0 nF/m limits displacement current between the conductors and shields, aiding drive fault detection. The copper resistance is 1.91 Ω/km, so thermal rise remains within allowed limits at the rated load. The outer jacket is molded from PUR, a thermoplastic polyurethane that resists exposure to oil and coolant on production lines. The internal geometry follows bulk cable type INK0605, which establishes the conductor spacing and shield layout.
Durability during continuous motion is supported by a flex-life rating of 5,000,000 cycles, making the cable suitable for high-speed drag chains and other moving carriers. At the controller end, the terminated RLS0721 circular connector mates directly with IndraDrive inverter modules, while the motor end has an AEH/RKS hybrid plug that seals against the motor housing. The jacket has a RAL 2003 (orange) color for clear visual recognition on the plant floor. Two pairs of 1.0 mm² control conductors and two individual 1.5 mm² control conductors transmit brake power and temperature signals without requiring separate harnesses.
