Product Description:
The RKL4529 is a flexible motor-power cable produced by Bosch Rexroth Indramat within the RKL Motor Power Cables series. It delivers drive output to IndraDrive and IndraDyn devices in automated plants, supporting fast axis motion while surviving continuous drag-chain movement. The cable’s PUR jacket, color-coded RAL 2003, resists cutting fluids and ensures unambiguous identification on crowded machine beds, making it a dedicated link between cabinet inverters and moving servo motors.
The overall cable diameter is 25.5 mm, giving ample space for a power core of 16.0 mm² conductors that minimise voltage drop during high-current acceleration. Mechanical life is rated for 5 million bending cycles when routed in an energy chain, provided the dynamic radius is kept to 7.5 × D; this figure defines the smallest loop the cable may follow without damaging the copper stranding or PUR insulation. Three phase cores plus a protective-earth lead are laid with short lay lengths to suppress electromagnetic emission, and the adhesion-free jacket simplifies removal during connector assembly.
Electrical loss across the copper bundle is limited to 1.21 Ω/km, a value that helps drives maintain tight torque regulation under extended cable runs. Integrated feedback and brake wiring can be paralleled because a control pair of 1.5 mm² shares the same bend-capable construction, while a distributed capacitance of 1.2 nF/m keeps reactive current within the ratings of standard drive filters. Installation teams can reference the specific weight of 1.140 kg/m when calculating drag-chain loading; for fixed routing the static bend radius of 5 × D permits tighter cabinet transitions without exceeding PUR strain limits.
