Product Description:

The RR52.1-7N-007-P-NN-FW is a Bosch Rexroth Indramat drive controller from the RD 500 Drive Controllers series. It converts a fixed DC link into variable three-phase output and uses field-oriented control so that industrial motors receive precise torque and speed commands. In automated production lines, the module serves as the actuator interface between higher-level controls and the motor. This arrangement helps the controller manage motor behavior directly while the PLC handles overall machine logic.

The controller is designed for a bus voltage window of 530 to 670 V, allowing operation on high-energy intermediate circuits commonly used in multi-axis cabinets. Within this range, it delivers a continuous mechanical output of 7.5 kW, which is the continuous motor shaft power it can support under rated thermal conditions. Power conversion relies on field oriented vector control, which resolves stator currents into d-q components to maintain accurate torque across the speed range. Heat generated by the power section is routed to a heat dissipation panel for drives up to 18.5 kW, so the cabinet can remain closed without forced airflow. The DC link is supplied by an Inverter DC stage that smooths the input and helps reduce ripple at the motor terminals.

The unit is supplied without a built-in brake chopper, so rapid deceleration requires a separate module for external braking resistance. The hardware belongs to Design Generation 1, making it suitable for first-generation RD 500 power sections and option cards. The standard function slot is not equipped, leaving that position open for an I/O or communication board if needed. The firmware is listed as ordered as a separate subposition, so the required software package is selected separately from the hardware. This ordering structure keeps the base unit distinct from the application-specific control software.
