Product Description:
The RD52.1-4N-007-L-NN-P1-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat and released within the RD 500 Drive Controllers series. It serves as the main power and regulation stage for induction or synchronous motors in automated equipment, converting control commands into regulated voltage and frequency so the motor can maintain commanded speed and torque. By linking the plant supply to the motor windings through insulated-gate power modules, the unit supports stable operation during load changes, start-up sequences, and normal production duty. This arrangement allows the controller to respond quickly to process demands without requiring a separate power conversion stage at the motor.
This model delivers a rated mechanical output of 7.5 kW, allowing continuous operation at that power level under normal thermal conditions. Its input network accepts three-phase mains from 380 to 480 V and uses a three-phase AC converter front end to rectify and reinvert line power for variable-frequency output. Voltage deviations of up to ±10 % are tolerated by the DC-link regulator, which helps the drive remain active during normal plant supply variation. Heat generated by switching losses is removed by forced-air cooling, with internal fans moving air across the heat sink to keep component temperatures within the intended operating range. This cooling method supports sustained motor control in enclosed industrial installations where internal heat buildup must be managed continuously.
The motion loop uses field-oriented vector control, which separates flux and torque control for accurate speed regulation at low motor speeds and during changing load conditions. For electromagnetic compatibility, the drive includes an integrated mains filter that reduces conducted interference without requiring a separate external filter assembly. Dynamic braking energy must be routed to an external resistor because the unit is supplied without a built-in brake chopper, so deceleration energy cannot be dissipated internally by the drive. The hardware is part of generation 1, which matches early RD 500 option cards used with this platform. This version suits installations that rely on established RD 500 accessories and standard closed-loop motor control behavior.
