Product Description:
The RD52.2-4B-007-L-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. Installed in cabinet-based automation lines, the unit sits between a three-phase mains source and an AC motor to regulate speed, position, and torque through pulse-width-modulated output. By managing motor performance electronically, it helps production equipment maintain process accuracy, reduce mechanical stress, and match energy use to real-time demand in conveyor, packaging, and machining applications. The cabinet-mounted design also suits centralized drive systems where power conversion and motor control are grouped in one enclosure.
The controller is fed from a three-phase AC supply and accepts line voltages from 380 to 480 V. Within that range, it tolerates variation of ±10%, which helps prevent nuisance trips when the plant network fluctuates. Its output stage is rated for 7.5 kW, so it can drive moderate-sized motors without external derating. Motor regulation is executed by field-oriented vector control, a method that separates flux and torque for better low-speed response and steadier control under changing load. These values set the electrical operating range for the RD52.2 unit when it is matched with motors and protective devices.
Integrated features inside the drive simplify installation. A built-in brake chopper dissipates regenerative energy during rapid deceleration, which can remove the need for an external resistor on many axes. Thermal management relies on forced air cooling, so the controller must be mounted with an unobstructed airflow path. Line-side harmonic suppression is handled by an integrated mains filter, which reduces conducted noise toward the plant supply. The unit is built in design generation 2, and the base model does not include optional function boards. The required control software is ordered separately.
