Product Description:

The Bosch Rexroth Indramat RD52.2-5B-003-L-NN-FW belongs to the RD 500 Drive Controllers series and regulates motor motion in automated installations such as conveyors, packaging lines, and material-handling cells. It links plant power to the motor leads, adjusting voltage and frequency to match commanded speed and torque. This drive controller serves as the central power modulator between the control system and the motor, allowing PLC or CNC commands to produce controlled mechanical movement. That arrangement helps a machine axis start, run, and stop under programmed control instead of applying fixed line power directly to the motor.

The controller draws power from a 3 x AC converter supply and is intended for networks up to 500 V, which suits common industrial mains. Internally, it uses field-oriented vector control to separate torque-producing and magnetizing current components, helping the drive maintain stable output at low speed and during load changes. Its continuous output is limited to 3.0 kW, so the connected motor must remain within that continuous power level during normal operation. Heat generated by the IGBT bridge is removed through forced air cooling, and the enclosure needs clear airflow to prevent temperature buildup. This cooling method supports steady operation in cabinets where natural convection alone would not be enough.

A built-in brake chopper dissipates regenerated energy during rapid deceleration, reducing the need for an external resistor in moderate braking duty. The unit is generation 2, which identifies its later control and power-stage revision within the product line. The option slots are not equipped, leaving the base unit without add-on cards until a required interface or function is installed. The firmware must be ordered as a separate subposition, so the software is selected independently from the hardware. This arrangement lets the drive match the intended application without changing the core power section.
