Product Description:
The RD41.1-6B-012-L drive controller is produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. As a closed-loop power module, it regulates three-phase induction or synchronous motors in material handling, packaging, and general automation cells. By converting incoming line power and modulating output frequency and voltage, the unit controls motor speed and torque according to setpoints from higher-level PLCs or motion cards. Its generation 1 design combines power electronics, control logic, and protective circuits in a single housing to simplify cabinet wiring. Feedback processing inside the controller helps the drive respond to load changes and maintain commanded motion during varying process demand.
The controller draws power from a 3-Phase AC 400 V ±15% mains supply and operates on an unregulated DC bus with up to 25 A of DC-link current. A nominal shaft power of 12.5 kW is available under continuous duty, while an overload capability of 1.5× for 60 s permits short bursts of additional torque during acceleration or process upsets. The unit accepts line frequencies of 50/60 Hz without adjustment. A built-in brake chopper diverts excess energy to an external resistor with a minimum value of 20 Ω during rapid deceleration, and the integrated line filter helps reduce conducted emissions. Forced-air cooling moves heat through dedicated channels to support stable thermal operation.
The aluminum frame size A enclosure stands 500 mm tall, spans 120 mm in width, and extends 360 mm in depth, so cabinet layout must allow room for cable bends and airflow. Net mass is 22 kg, which should be considered when selecting the mounting method and handling equipment. At least 100 mm of clearance must be maintained above and below the heat sink to preserve the cooling airflow path. Crowding adjacent modules too closely can obstruct airflow and reduce cooling effectiveness. The braking resistor should be mounted outside this air corridor so exhaust heat does not raise the internal enclosure temperature.
