Product Description:

The RD52.2-4B-015-D-A1-FW is a drive controller produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It links plant power to an induction or synchronous motor and governs torque and speed through closed-loop current regulation and voltage modulation. This operating approach suits automated stations that need stable motor response during acceleration, steady running, and routine load changes across conveyors, process equipment, and similar machinery. Because it can operate with either induction or synchronous motors, the controller fits mixed-machine installations where one drive platform is used across several axis types.

For power handling, the unit delivers a continuous output of 15.0 kW. It accepts line voltages from 380 to 480 V and uses a three-phase AC converter supply topology, so it can connect directly to common factory distribution boards. Input variation of ±10 % is tolerated without derating, which helps in facilities with fluctuating line conditions. Speed and torque are processed with field-oriented vector control, so the controller maintains dynamic response even under load changes. The available voltage window also covers regional 400 V and 440 V utility classes and helps match the drive with compatible motors and cabling.

Thermal management is handled by a plug-through cooler that removes waste heat through the panel wall, helping keep cabinet temperatures within acceptable limits and reducing particulate buildup on internal circuitry. During deceleration, a built-in brake chopper directs regenerative energy to external resistors to prevent DC-link overvoltage. An integrated line filter suppresses conducted emissions, so additional line reactors are often unnecessary. Operational safety is reinforced by the starting lockout function and by standby power terminals that permit external monitoring when the main bus is off. This model belongs to design generation 2 within the RD 500 platform.
