RL2-045GBB by Bosch Rexroth Indramat

The RL2-045GBB motor power cable is produced by Bosch Rexroth Indramat within the RL2 Motor Power Cables series. It serves as the fixed link between a drive controller and a second-generation Rexroth servo motor, carrying both mains power and feedback lines inside automated conveyor, handling, and packaging equipment. By matching the electrical interface used for this product group, the cable supports consistent installation and predictable performance in dynamic cable carrier applications.

The cable is rated for >= 5,000,000 bending cycles, so it tolerates repeated motion in energy chains without conductor fatigue. A jacket of PUR (Orange RAL 2003) resists oil and abrasion while providing high visibility inside a machine enclosure. Power cores with a cross-section of 6.0 mm² help limit voltage drop over long runs and are sized for the drive's nominal current. The assembly terminates in a field-serviceable M40 (Plug V) connector that matches the motor's power port. For the three-phase conductors, the permissible line-to-line voltage is 600/1000 V, allowing this cable to operate on common 400 VAC plant supplies with ample margin. The design is listed as Basic, indicating a simplified shielding concept that still satisfies EMC limits for standard factory environments.

Mechanical clearances require a fixed bend radius of 5 × D and a dynamic minimum of 7.5 × D, so routing inside a drag chain must respect these limits to avoid jacket kinking. Copper conductors may reach +90 °C when the cable is clamped in place and +80 °C under continuous flexing, which suits drive overload conditions. An insulation resistance of >= 20 M?/km at 20 °C helps keep leakage current below drive trip thresholds, and the separate signal pair is rated for 450/750 V to support encoder or brake circuits without additional wiring.
