RL2-563GBB by Bosch Rexroth Indramat

The RL2-563GBB cable belongs to the RL2 Motor Power Cables series from Bosch Rexroth Indramat. As an extension lead between a drive controller and a second-generation Indramat motor, it routes three-phase power and associated signal cores in one assembly for use in gantry systems, packaging machinery, and general automation. The model extends factory-supplied motor pigtails without altering shielding practices and keeps the connector interface standardized across the product group.

In dynamic cable tracks, the assembly withstands 5,000,000 bending cycles, indicating its expected service life during continuous motion. The basic cable design uses tinned copper conductors sized at 6.0 mm², giving the power cores a current capacity suitable for mid-frame servo axes. During fixed installation, each conductor may rise to 90 °C without degrading insulation, while flexible operation is limited to a lower temperature. To avoid over-stretching, the minimum dynamic bending radius is 7.5xD, where D is the outer diameter. Power pairs are insulated to 600/1000 V, and the auxiliary signal cores operate at 450/750 V, so one cable can carry both drive voltage and related signal potentials.

For applications that involve repeated coiling outside a carrier, the flexible temperature ceiling is 80 °C, which helps maintain jacket integrity under thermal load. When the cable is secured in place, the static bend requirement relaxes to 5xD, allowing tighter cabinet routing. The outer sheath is made of PUR, a material chosen for abrasion resistance and coolant resistance. A factory-crimped M58 circular connector mates directly with second-generation Bosch Rexroth motors, so the extension cable can be installed without field-terminating high-voltage lugs. Its layout supports the pin assignments used by the second motor generation and maintains continuity with matching cable assemblies in the same product group.
