Product Description:
The RD52.2-4B-003-L-A1-FW is a drive controller produced by Bosch Rexroth Indramat and belongs to the RD 500 Drive Controllers series. Designed for industrial automation, the unit interfaces with induction or synchronous AC motors and regulates torque, speed, and direction in multi-axis machinery. By processing real-time feedback and modulating motor output, the controller serves as the central power stage between the plant mains and the motion hardware. This arrangement supports coordinated operation in conveyors, tooling heads, process pumps, and similar equipment where stable motor response is required during changing load conditions.
Internally, the controller uses field-oriented vector control, so current components are resolved into flux-producing and torque-producing vectors for precise dynamic response during acceleration and speed changes. It is supplied through a three-phase AC converter front end that accepts line voltages from 380–480 V and remains functional within a ±10 % tolerance window, which helps it operate reliably where incoming utility levels vary. The power section is rated at 3.0 kW, making it suitable for medium-frame motor duties. External standby power can be used, and a starting lockout circuit helps prevent unintended energization when the system is not meant to run.
Thermal management relies on forced air cooling, so cabinet airflow must be maintained to keep semiconductor temperatures within normal operating limits during continuous use. The built-in brake chopper reduces the need for separate braking hardware and simplifies resistor connection where decelerating loads return energy to the drive. As a generation 2 design, the controller keeps platform continuity while using faster internal processing to support control response and stable regulation. The integrated mains filter helps reduce conducted interference on the supply side and limits the spread of switching noise to upstream equipment.
