Product Description:
The RD52.1-7N-005-L-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat as part of the RD 500 Drive Controllers series. It is an inverter that modulates the electrical output of a shared DC bus so that asynchronous or synchronous motors receive precise voltage and frequency profiles. In automated production cells, the unit regulates acceleration, speed, and torque for equipment such as conveyors, extruders, and pumps. This allows connected machines to follow commanded motion profiles with stable control during variable operating demands.
To match industrial DC link supplies, the controller operates on a bus voltage from 530 to 670 V, which supports stable operation during normal line fluctuation or regenerative conditions. The unit has a continuous power capability of 5.5 kW, which indicates the maximum motor load it can support under rated conditions. Motion control uses field-oriented vector control, an algorithm that separates stator currents into torque-producing and flux-producing components for fast dynamic response. The module is an Inverter DC unit, so it receives pre-rectified power instead of direct three-phase mains input. Heat is removed by forced air cooling, using an internal fan to keep power components within their intended operating temperature range during continuous duty.
The drive is supplied without built-in brake chopper, so applications with high regenerative peaks require an external braking resistor or a separate chopper module. The unit is in Design Generation 1, which is the first mechanical and electrical layout used for this RD 500 version. The required operating software is ordered as a separate firmware subposition. The drive is not equipped with optional technology extensions, so it remains in a baseline configuration unless add-on cards are installed later.
