Product Description:
The RD52.1-4B-022-L-F1-FW is a drive controller produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. Installed between a plant’s three-phase mains and its motor, the unit executes real-time current and voltage modulation so an automation cell can hold commanded speed and torque values under fluctuating loads. This controller serves as the central power and control element in packaging, material-handling, and general motion applications that require precise vector-based regulation.
The power section is designed for grids from 380 to 480 V and can accept line deviations of ±10 %, reducing sensitivity to common industrial supply swings. Because the supply type is a three-phase AC converter, the unit rectifies incoming AC power and reconstructs a variable AC output that matches process demands. Its continuous mechanical output reaches 22 kW, allowing it to drive medium-sized pumps, extruders, or conveyor motors. Motion is processed with field-oriented vector control; this algorithm regulates flux and torque components independently for fast dynamic response. Deceleration energy is dissipated internally through a built-in brake chopper, which directs excess DC-bus voltage to a braking resistor and eliminates the need for an external chopper module.
Thermal management relies on forced air cooling; a dedicated fan pulls cabinet air across the heat sink to keep semiconductor temperatures within limits during continuous operation. Input harmonic suppression is handled by an integrated mains filter, allowing compliance with plant EMC rules without extra line components. The controller belongs to Design Generation 1, which sets its mechanical frame size and connector layout. The unit also provides current filter signal feedback at terminals U6, V6, and W6, allowing harmonic attenuation to be checked during operation.
