Product Description:
The RKL4534 cable is produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is a dedicated motor power lead intended to route a three-phase supply and auxiliary conductors between Indramat drives and servo motors in automated machinery. By combining power cores and signal pairs in one shielded assembly, the cable simplifies cabinet wiring and maintains electromagnetic compatibility on fast-switching inverter outputs. This combined arrangement also reduces the number of separate cable runs required between the drive and motor.
The power circuit uses conductors with a 10.0 mm² cross-sectional area, allowing drive output current to be transmitted with limited voltage drop, while the copper loop resistance is 1.91 Ω/km. The cable has an outer diameter of 22.2 mm, allowing it to fit common energy-chain separators. Distributed capacitance is 1.0 nF/m, which helps the inverter maintain rise-time control and reduces reflected-wave stress on motor insulation. A mechanical service life of 5 million bending cycles supports continuous movement in drag-chain applications, and the cable tolerates the torsion encountered on rotating tables. Two auxiliary pairs provide connections for brake release or temperature sensor circuits without requiring separate cabling. Cores 5 and 6 have a cross-sectional area of 1.0 mm², while cores 7 and 8 have a cross-sectional area of 1.5 mm².
Field termination is simplified by the premolded INS0482/L10 plug connector, which matches compatible Indramat motor receptacles. The oil-resistant sheath is made of PUR to protect the cable in areas exposed to coolants, lubricants, and regular mechanical movement. Its high-visibility RAL 2003 orange jacket makes the motor power cable easy to identify in a crowded cable tray. Dynamic routing requires a minimum bend radius of 7.5 × D, while a fixed installation permits a minimum bend radius of 5 × D. Bulk cable is available under the INK0605 type code for installations that require cut lengths. The internal shield is bonded to the connector’s 360-degree shield ring to maintain continuous shielding at the termination point.
