RLB2-102GDB by Bosch Rexroth Indramat

The RLB2-102GDB motor power cable is manufactured by Bosch Rexroth Indramat as part of the RLB Motor Power Cables series. It links drive converters to servomotors in automated machines, carrying main phase energy and auxiliary signals between ctrlX DRIVE power modules and MS2(X) motor terminals. Used inside control cabinets or routed through drag-chain systems, the cable supports accurate torque delivery by pairing conductor cross-sections with the electrical demands of modern servo axes and limiting capacitive load on the drive outputs.

The internal geometry follows a basic layout that groups four phase cores with separate auxiliaries, and this arrangement is specified as 4x L + 4x 1.0 mm² + 2x 1.5 mm². Two additional signal pairs, labeled as 2 × 1.0 mm² and 2 × 1.5 mm², simplify connection of brake circuits or temperature sensors. An outer diameter of 18.2 mm allows routing through standard cable ducts without excessive bend stress, while the jacket material is PUR, providing abrasion resistance and compatibility with oils and coolants commonly present in machinery. The sheath is colored RAL 2003 Orange for immediate identification of live power wiring. Dielectric design holds the leakage capacitance to 0.5 nF/m, helping the drive maintain short rise times and reducing common-mode currents that can interfere with adjacent signal cables.

Thermal endurance has two limits: conductors in fixed installation can reach +90 °C, whereas continually flexed sections must remain below +80 °C. These limits let the cable handle cyclic acceleration inside energy chains without premature insulation aging. Full electrical compatibility is confirmed for ctrlX DRIVE controllers, and mechanical interfaces match the winding and terminal geometry of MS2(X) synchronous motors, reducing installation effort when upgrading or expanding Rexroth motion systems.
