RL2-022CBB by Bosch Rexroth Indramat

The RL2-022CBB power cable is produced by Bosch Rexroth Indramat for the RL2 Motor Power Cables series. It provides the primary energy pathway between IndraDrive servo amplifiers and matching MS2x motors inside automated cells, carrying three-phase power and protective earth in one sheath. Within industrial automation systems, this cable replaces loose wiring with a pre-assembled line that maintains consistent conductor spacing and insulation thickness, helping drives deliver commanded torque without unnecessary electrical loss.

The RL2 cable uses a basic construction that groups eight conductors into a single jacket. Four phase cores share a collective cross section of 1.0 mm², while a second quartet serves auxiliary functions. The internal layout is identified as 4x L + 4x 0.75 mm², simplifying part selection when matching cable impedance to drive output current. For controller integration, the assembly is approved for IndraDrive connection and terminates on the motor side with an M23 Power Connector that locks with a quarter turn. Dynamic routing is supported because the copper bundle endures continuous motion down to a bend radius of 7.5xD; this rating allows installation in energy chains without violating insulation limits. On the cabinet end, the conductors land on spring terminals through a direct connection technique, eliminating intermediate adapters and reducing contact resistance.

In fixed installation, the jacket can loop to a smaller 5xD radius without cracking the PVC outer layer during routing around cabinet corners. Laboratory testing confirms up to 5,000,000 flexing cycles before conductor fatigue appears under repeated motion. Compatibility with MS2x motors with Plug U of the 2nd generation aligns the cable with current Rexroth servo platforms and the corresponding motor-side interface.
