Product Description:

The RKL0063 motor power cable is produced by Bosch Rexroth Indramat as part of the RKL Motor Power Cables series. It is intended to link servo drives to their corresponding motors within automated machinery, supplying three-phase energy and auxiliary control cores while withstanding repetitive movement. By integrating power and feedback conductors in a single jacket, the cable simplifies routing inside machine frames and robotic axes and maintains electrical integrity under dynamic load conditions.

The cable is rated for 600 V AC operating voltage, supporting standard inverter outputs found in industrial drive systems. Its conductor layout of 4x1.0 + 2x(2x0.75) mm² separates motor phases from signal pairs; the four phase cores each use a cross-section of 1.0 mm², while every signal core is sized at 0.75 mm² to suit brake release or temperature sensors. A nominal outside diameter of 12.0 mm permits entry through common M16 and M20 glands without excessive compression. The structure is qualified for drag chain motion, allowing millions of bending cycles in linear transfer stations and pick-and-place modules.

Electrical parameters include a capacitance of 0.6 nF/m, which minimizes reactive charging current over long dynamic runs. The loop resistance of 19.5 Ohm/km defines acceptable length before voltage drop compromises motor torque. An outer sheath made from PUR protects the cores against oils, coolants, and continuous flexing; its surface is Orange (RAL 2003) for clear safety identification along cable tracks. Bosch Rexroth assigns bulk cable code INK0653 to ensure ongoing material consistency across different batch lengths. Because the design is explicitly approved for drag-chain use, installers can route tight radii without adding external conduit or strain-relief accessories.
