Product Description:
The RKL4714 motor power cable is manufactured by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. It is intended for fixed-to-moving connections between Indramat controllers and servo motors in automated machining centres, handling systems, and other installations that rely on continuous carrier motion. The cable carries phase conductors, control cores, and protective earth in a single jacket so that one assembly can deliver motor power and feedback-related signals without additional harnesses. This integration reduces cabinet wiring effort and maintains signal integrity over long drag-chain travel lengths.
Mechanical endurance is defined for up to 5 million bending cycles when the cable is routed inside drag-chains, a rating helped by its ability to flex within a temperature window of -20 to +40 °C. During motion the design observes a minimum dynamic bend radius of 7.5xD, while 5xD is sufficient for fixed installation, and the overall outer diameter of 12.2 mm aids compact chain layouts. Phase insulation supports a maximum UL operating voltage of 600 V AC, allowing compatibility with standard Rexroth inverter outputs. The cable is approved for use in drag chains, so no additional mechanical guidance is required.
The bulk conductor set is identified as INK0650, a layout that assigns three power cores of 1.5 mm² each and two control pairs of 0.75 mm² to separate compartments. A matte, adhesion-free outer layer made from PUR prevents the chain links from sticking and resists common coolants. Electrical terminations are supplied ready-made: the controller end is fitted with a RLS0721/K02 connector, while the motor side mates to an RLK1301 plug, removing field crimping work. The VDE rating of 300/500 V covers European installations that run below UL limits.
