Product Description:
The RD52.1-7N-001-L-NN-FW is an AC inverter module designed by Bosch Rexroth Indramat for use within the RD 500 Drive Controllers series. Intended for cabinet-mounted installation in production lines and process plants, it converts the energy of a common DC link into variable voltage and frequency for asynchronous motors. By doing so, the unit supports closed-loop speed, torque, and positioning tasks in conveyors, extruders, and machine-tool spindles. Because the power conversion stage is separated from the mains supply section, it fits systems that centralize rectification and distribute DC energy to multiple drive axes. This architecture is common in multi-axis cabinets where regenerated energy from decelerating motors can be shared on the bus.
The module operates from a DC link within 530 to 670 V, so the upstream rectifier or capacitor bank must remain inside this window. It uses an inverter DC supply rather than a direct AC mains input, which allows several axes to share stored bus energy. Motor regulation is handled through field-oriented vector control, which separates flux and torque for stable response at low speed and during changing loads. Stable low-speed control is especially useful where smooth starts and consistent torque affect process quality. Heat is removed by forced air cooling, so the cabinet must provide clear airflow paths across the heat sink channels and avoid blocked intake areas. The unit is supplied without a built-in brake chopper, so applications with frequent deceleration or high reflected inertia require an external braking arrangement.
The unit is in design generation 1, which places it in the earliest release of the RD52 electronics. Both internal option slots are not equipped, so no expansion cards are installed in the base configuration. The required drive software must be ordered as a separate subposition, so it is not included with the base hardware. Ordering the software separately allows the control package to match the intended motor and operating method. This product is classified as a Drive Controller, meaning it serves as the controlled power stage between the DC bus and the motor.
