Product Description:
The RD52.2-4B-005-P-A1-FW unit is produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. It is a modular controller that converts three-phase mains power into a regulated output for induction or synchronous motors, enabling closed-loop speed and torque control in automated conveyor, packaging, and material-handling equipment. By interfacing with higher-level PLCs, the controller coordinates motion sequences and maintains process accuracy across multiple axes. This type of controller is commonly used where motors must accelerate smoothly, hold speed under changing loads, and respond predictably to commands from the machine control system.
This second-generation design delivers a rated output of 5.5 kW and accepts a line voltage from 380 to 480 V. Input fluctuations are accommodated by a tolerance of ±10%, helping the drive remain stable on power grids with moderate variation. Its control core uses field-oriented vector control, which allows precise current and flux regulation for responsive performance even at low speeds. That control method is useful in applications that need steady torque at reduced speed, such as conveyors that start under load or handling axes that make repeated speed corrections. A built-in brake chopper dissipates regenerated energy during rapid deceleration, protecting the DC bus during frequent starts, stops, and speed changes.
Thermal management is handled by a heat dissipation panel for units up to 18.5 kW, which helps simplify cabinet airflow while the controller operates continuously at rated load. The drive is powered from a three-phase AC converter supply, and an integrated mains filter reduces conducted emissions without requiring a separate filter module. Safety and energy functions include external standby power with starting lockout, which helps lower idle consumption and prevents unintended restarts after shutdown. With braking and input filtering inside the unit, fewer external modules are needed around the controller. The second-generation platform also supports faster diagnostic access during operation, which helps the control system respond more quickly to changing load conditions.
