Product Description:
The RD52.1-4B-315-F-VW-FW is a drive controller produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It coordinates motor currents and voltages so that large industrial AC machines follow speed or torque references issued by upper-level automation systems. By continuously processing feedback signals, the unit converts control commands into three-phase output waveforms that match the required mechanical response, making it suitable for automated conveyors, extruders, and material-forming equipment where high-power regulation is essential.
At the heart of its regulation algorithm is field-oriented vector control, a method that decouples stator flux and torque to keep motor dynamics linear even under load transients. The controller is specified for a nominal output of 315 kW, allowing it to drive large motors without derating. It draws power from a three-phase mains network rated between 380 to 480 V and accepts a tolerance of ±10 %, so line voltage fluctuations do not impair operation. Because the power section is configured as a 3 x AC converter, the unit rectifies incoming AC, regulates the DC link, and inverts the energy back to a variable-frequency waveform suitable for precise speed control. This version belongs to design generation 1.
In addition to the primary power stage, the controller integrates a built-in brake chopper that diverts regenerative energy to external resistors during rapid deceleration. Thermal management is handled by forced-air cooling with integrated liquid circulation; an internal fan moves air across heat sinks that are thermally tied to a coolant circuit, maintaining component temperatures during continuous high load. A mains filter is already installed to attenuate conducted emissions, and application-specific functionality is extended through the V1 + W1 option combination.
