Product Description:
The RKL4700 motor power cable is produced by Bosch Rexroth Indramat and belongs to the RKL Motor Power Cables series. Designed for servo drive installations, this cable links drive controllers to synchronous motors, carrying both power and control signals within a single assembly for compact routing in automation cabinets and machine frames.
At the core of the assembly is a circular sheath with an outside diameter of 12.0 mm, allowing standard PG and metric glands to seal the entry points. Power conductors inside the bundle use a cross-section of 1.0 mm², providing adequate ampacity for medium-frame servo axes, while a separate control pair is sized at 0.75 mm² for brake release or sensor reference lines. The cable carries energy to the motor over a 3 power phase set that terminates at connector RLK1201 and returns to the controller through RLS0721/K01 on the opposite end. Insulation between cores supports a continuous rating of 300/500 V, and copper conductor resistance is specified at 19.5 Ω/km, ensuring limited voltage drop across typical machine lengths.
Electrical interaction with neighbouring lines is minimized by a discharge capacitance of 0.6 nF/m. Mechanical durability is provided by a jacket manufactured from PUR in the high-visibility RAL 2003 orange tone, giving abrasion resistance and easy identification in cable trays. For fixed routing the cable can be laid with a minimum bend radius of 5 × D, while dynamic chains require a larger radius of 7.5 × D to avoid conductor fatigue. These characteristics, together with the INK0653 bulk construction and the three-core shield, support reliable motor performance in continuous-duty production environments.
