Product Description:
The RKL4456 is a motor power cable supplied by Bosch Rexroth Indramat within the RKL Motor Power Cables series. Intended for servo-drive installations, it links the inverter output to the motor terminal box while carrying conductors for thermal sensor feedback. Its construction and connector interfaces allow system builders to route power safely between the controller cabinet and the machine axis in industrial automation environments. The specified connector formats provide compatible connections at both ends of the cable.
The cable core contains 4 × 10.0 mm² copper power conductors that deliver the main phase current to the motor. A total shield made from tinned copper braid surrounds the core, limiting electromagnetic emissions and protecting drive electronics from coupled noise. The composite uses bulk cable type INK0605 and has an overall diameter of 22.2 mm. Its dimensional tolerance is ±1.0 mm, allowing the cable to fit compatible gland plates. A PUR outer jacket resists oil and weld spatter, while the controller-side INS0623 plug mates directly with compatible Rexroth drive modules. When permanently installed, the cable can be routed with a minimum bend radius of 5 × D without damaging the conductors.
Supplementary circuits use 2 × 1.0 mm² and 2 × 1.5 mm² conductors for brake and sensor connections. In dynamic cable tracks, the cable can flex around a minimum radius of 7.5 × D. Its conductors support a maximum temperature of +80 °C under continuous load. The outer sheath is orange (RAL 2003), making the cable easy to identify among other machine wiring. Its matte, low-adhesion surface supports simple cleaning in areas where chips or adhesives may be present. An AEH/RKS motor-side connector mates with terminal box size 4 hardware, providing a direct connection between the controller cabinet and the servo motor.
