Product Description:
The RD52.2-4B-003-L-NN-FW is manufactured by Bosch Rexroth Indramat as part of the RD 500 Drive Controllers series. Intended for industrial automation panels, the unit works as an AC drive that converts incoming three-phase power into controlled output for induction and synchronous motors. This allows coordinated speed and torque regulation on production machinery such as conveyors, processing equipment, and general factory systems. No optional function modules are fitted, so the expansion slots remain free for later interface or I/O additions. The drive is suited for applications that need adjustable motor speed during start-up, steady operation, and controlled slowing.
Its hardware incorporates a built-in brake chopper that routes regenerated energy to an external resistor, preventing DC-link overvoltage during rapid deceleration cycles. Motion is processed with field-oriented vector control, so current vectors are aligned with rotor flux for precise torque response even at low speed. This control method helps the motor respond smoothly when load conditions change during operation. Thermal management relies on forced air cooling, letting the controller maintain nominal output up to 3.0 kW without derating. The input section accepts a line between 380 to 480 V, and regulation tolerates line swings of ±10%. Because the mains filter is already integrated, no additional EMC hardware is required at the cabinet entry.
The power section uses a 3 × AC converter topology, so rectification and inversion are combined in one housing together with an integrated mains filter that attenuates conducted noise toward the utility feed. As a generation 2 design, the controller shares mechanical dimensions and interface pinouts with earlier RD units while offering faster processing for the vector algorithm. This layout keeps the drive compact and supports installation in cabinets already arranged for the RD platform. Application-specific software must be ordered separately, allowing the same hardware to be adapted for pumps, fans, or servo duties.
