Product Description:
The RD52.2-4B-007-D-NN-FW is produced by Bosch Rexroth Indramat and belongs to the RD 500 Drive Controllers series. It is used in industrial automation to modulate motor speed and torque through closed-loop vector algorithms. This helps maintain stable operation when load demand changes during production. It also gives machine builders a compact controller for conveyor lines, material-handling axes, and process pumps.
This unit delivers a rated output of 7.5 kW, matching small to mid-frame motors that must maintain constant torque across varying loads. It accepts an input voltage range of 380 to 480 V and derives its DC link from a Converter 3 x AC input, so it can be wired directly to common three-phase plant supplies. Component tolerances of ±10 % allow for normal voltage variation without nuisance trips. Speed regulation is executed by field-oriented vector control, which separates flux and torque currents for quick response during acceleration or deceleration. Its three-phase input arrangement suits standard industrial distribution systems used for inverter-driven motors.
Braking energy is dissipated internally by a built-in brake chopper, eliminating the need for an external resistor module on most dynamic axes. Thermal losses are carried to the rear of the cabinet through the plug-through cooler (<= 110 kW), which helps keep heat out of the main airflow path. This layout can help reduce the cooling burden inside the enclosure. An integrated line filter suppresses conducted emissions and simplifies EMC compliance in standard installations. The drive is identified as design generation 2, indicating an updated hardware revision. Some optional functions are not included, so the controller can be fitted with only the option cards needed for the intended network or I/O layout.
