Product Description:
The RD52.1-7N-015-L-V1-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. Positioned between a plant’s DC bus and an industrial motor, the module synthesizes three-phase output waveforms that follow torque and speed commands issued by a PLC. By coordinating current, voltage, and position feedback when available, it maintains repeatable motion profiles for conveyors, pumps, and positioning axes used throughout automated production cells and material-handling systems. This control method helps the drive respond smoothly to changing load conditions during acceleration, steady operation, and deceleration.
The unit draws its intermediate-circuit energy from an inverter DC supply and operates within a link voltage window of 530 to 670 V. A continuous output capability of 15.0 kW makes it suitable for mid-range induction or synchronous motors used on extrusion, palletizing, or mixing equipment. Regulation is executed with field-oriented vector control, which resolves stator currents into separate torque and flux components for precise low-speed performance and stable motor response. Heat is removed through forced air cooling, so fans mounted on the housing move air across the heat sink and require clear intake and exhaust paths in the cabinet.
Regenerated energy during braking is returned to the DC link because the controller ships without a built-in brake chopper, so systems with frequent deceleration require an external resistor. Control electronics stay active through an external 24 V standby power feed, which allows communication and parameter access when the main link is de-energized. The product is generation 1, and this version uses the corresponding mechanical format and connector style. The unit is supplied without software, and the firmware must be ordered as a separate subposition so the control functions can be matched to the motor and network in use.
