Product Description:
The RKL4710 cable is a dedicated motor power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It is intended to link drive controllers to synchronous servo motors in automated machinery and other modern equipment. The construction bundles power conductors, control pairs, and protective earth under a common sheath, so panel wiring is simplified and chain routing requires fewer tracks. In such installations the cable carries motor current, brake supply, and sensor signals while tolerating continuous motion inside energy chains and robotic axes.
Mechanical service life and geometric limits define suitability in moving installations. The cable endures 5,000,000 bending cycles, supporting high-duty drag-chain applications. When installed statically the minimum bend radius is 5 x D, whereas dynamic routing requires 7.5 x D to avoid conductor fatigue. Its core assembly of 4x6.0 mm² + 2x1.0 mm² + 2x1.5 mm² separates power phases, brake wires, and temperature leads, reducing crosstalk. A circular sheath diameter of 18.5 mm fits standard clamping modules and ensures sufficient space for coolant airflow around adjacent cables.
Electrical characteristics complete the performance profile. At 20 °C the loop resistance is 3.30 Ω/km, a value used to predict voltage drop and to size over-current protection. Typical mutual capacitance of 0.8 nF/m influences drive filter design and limits maximum allowable length in high-frequency switching environments. The outer jacket is formed from PUR (adhesion-free, matte), giving abrasion, oil, and coolant resistance while sliding in cable tracks. Power cores may be operated at up to 300/500 V, allowing the same trunk to carry both main phase voltage and earth conductor without separate conduit for standard servo systems.
