Product Description:

The RD52.1-4B-015-P-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. In factory automation cells, it links the plant power bus to vector-controlled motors and provides closed-loop speed and torque regulation for conveyors, extruders, and similar processes. This supports stable motor operation when process loads rise and fall during normal production. It also helps connected equipment respond smoothly to command changes without abrupt speed variation.

This controller delivers a nominal output of 15.0 kW, so the continuous power level is suited to medium-duty industrial drive tasks. It draws its DC link from line voltages between 380 to 480 V, and the allowable input tolerance of ±10 % helps the unit remain operational during moderate supply fluctuation. A built-in brake chopper directs regenerated energy to an external resistor during deceleration, while field-oriented vector control separates magnetizing and torque-producing current components for accurate motor response across the speed range. Line-side harmonics are reduced by an integrated mains filter, which helps the installation maintain cleaner electrical behavior on the supply network.

Thermal management for the listed power range is supported by a heat dissipation panel, so the unit mounts to a metal surface that conducts losses to ambient air without requiring additional fans for ratings up to 18.5 kW. The incoming supply uses a three-phase AC converter input, which matches the power systems commonly found in industrial facilities. The product belongs to Design generation 1, and the auxiliary option slots remain open because no extra functions are equipped. This leaves the controller in a straightforward base configuration for applications that do not require added option hardware.
