Product Description:
The RD52.1-4B-007-P-V1-FW is an AC drive unit produced by Bosch Rexroth Indramat within the RD 500 Drive Controllers series. It governs three-phase induction motors in automated machinery by converting incoming line power into a regulated output that follows commanded speed and torque profiles during acceleration, deceleration, and steady-state operation. By combining the control electronics, power semiconductors, and protective functions in one enclosure, the unit simplifies cabinet layouts and supports centralized or distributed motion systems used in conveyors, pumps, and general material-handling equipment. This integrated arrangement keeps drive-related functions together in a single mounting location and reduces the need for separate auxiliary modules.
This model belongs to design generation 1 and is rated for a continuous mechanical output of 7.5 kW. The power stage accepts a line voltage range of 380 to 480 V through a three-phase AC converter front end, so it can connect to common industrial supplies without extra input conversion hardware. Within that range, the electronics tolerate line fluctuations of ±10% without derating. Excess heat from the IGBTs is routed to a rear-wall heat dissipation panel for outputs up to 18.5 kW, allowing the module to be mounted on the rear wall of a control cabinet without active airflow. That cooling arrangement supports rear-panel installation where cabinet space is limited and forced ventilation is not desired.
Operational behavior is managed through field-oriented vector control, which allows rapid current modulation and responsive torque control under changing load conditions. Dynamic braking energy is processed internally by a built-in brake chopper, eliminating the need for a separate resistor circuit during moderate deceleration cycles. To support emergency logic and parameter retention, an external supply can provide external 24 V standby power when line power is off. The power stack is protected further by an integrated line filter, which helps limit high-frequency noise returning to the facility supply. Software for this device is ordered separately, allowing the required revision to be selected for the application.
