Product Description:
The RD52.1-4B-003-D-NN-FW is a drive controller produced by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It governs three-phase induction or synchronous motors in automated machinery, adjusting torque and speed through closed-loop current and voltage regulation so that motion sequences remain repeatable in assembly, packaging, and material-handling lines. It can be used where repeatable acceleration, deceleration, and steady running are required across multiple machine steps. Function slots are present, but no optional technology functions are fitted.
This controller operates on a three-phase supply within a voltage window of 380 to 480 V and is configured as a Converter 3 x AC unit, which means rectification and DC-link formation are built in. Because the rectifier is integrated, the incoming AC supply is converted inside the controller before the inverter stage feeds the motor. Incoming mains can vary by ±10 % without derating, supporting grids that experience modest fluctuations. The power section is sized for a continuous mechanical output of 3.0 kW, which suits small and medium production axes in automated equipment. Motor flux is managed with field oriented vector control; this algorithm keeps the stator and rotor fields at 90 degrees to improve dynamic torque response and support accurate positioning after sudden load changes.
A built-in brake chopper directs regenerated energy to an external resistor so deceleration does not raise the DC-bus voltage above safe limits. Thermal management relies on a plug-through cooler; heat is transferred out of the cabinet through a bonded heat sink, which helps reduce internal enclosure temperature and keeps surrounding control hardware cooler. Conducted interference is attenuated by an integrated mains filter, so a separate line filter is not required in most panels. The unit is identified as design generation 1, indicating compatibility with first-generation option cards. The open function slots allow optional hardware to be added later if the application requires extra features.
