Product Description:
The RD52.2-4B-015-L-NN-FW drive controller is manufactured by Bosch Rexroth Indramat as part of the RD 500 Drive Controllers series. It is intended for integration in industrial automation cells where closed-loop control is used for precise motor speed and torque regulation. By converting incoming three-phase line power into a controlled output waveform, it serves as the actuator interface for packaging lines, material-handling equipment, and general machinery. Its design matches other units in the series, which helps maintain a consistent panel layout.
On the electrical side, the converter accepts a supply of 380 to 480 V AC and tolerates line fluctuations of ±10 %, which reduces sensitivity to plant voltage swings. It delivers a continuous mechanical output of 15.0 kW, making it suitable for mid-range pump, fan, and process-drive duties. Motor magnetization and torque production are managed by field-oriented vector control, which adjusts stator currents in real time for fast dynamic response. When decelerating large inertial loads, a built-in brake chopper routes regenerated energy to external resistors so the DC link voltage stays within limits. An integrated line filter attenuates conducted emissions and supports cabinet installation without an added external line filter.
Thermal management is handled by forced-air cooling, and the blower sweeps air across the heat-dissipating fins to keep semiconductor temperatures within their operating range. The hardware belongs to design generation 2, which supports the RD 500 parameter set and remains compatible with earlier fieldbus options. Incoming power is provided through a three-phase AC input rectifier stage that feeds the shared DC bus for multiple axes. Optional application-specific functions are not equipped, so the controller remains configured for standard drive operation.
