Product Description:
The RD52.1-7N-037-L-NN-FW belongs to the RD 500 Drive Controllers series developed by Bosch Rexroth Indramat. It is a drive controller intended to regulate three-phase induction or synchronous motors in automated machinery by converting constant DC bus energy into variable AC output that matches commanded speed and torque. This allows the connected motor to respond accurately to changing load conditions during acceleration, deceleration, and steady operation. The model is used in the 37 kW power class where stable speed regulation and dynamic torque response are important for production equipment.
The controller delivers a nominal output of 37 kW while drawing from a DC link that can range from 530 to 670 V. Motor flux and torque are processed with field-oriented vector control, so the drive keeps current aligned correctly during rapid load changes and low-speed operation. Thermal management relies on forced air cooling, and the cabinet must provide an airflow path to remove switching and conduction losses from the heat sink. The supply interface uses an inverter DC feed from a separate rectifier module, which supports shared bus arrangements and allows regenerative energy to circulate on the DC bus. Because the power stage depends on an external DC source, it can be integrated into multi-drive systems that distribute bus energy across several axes.
The unit is supplied without a built-in brake chopper, so excess regenerative energy must be handled by an external resistor network or returned to the mains through an active front end. The product is generation 1, which places it in the first hardware generation of this model line. Any required control firmware is supplied separately, and firmware must be ordered as a separate subposition. The optional technology slots are not equipped, so no additional communication or I/O option boards are installed in the base unit. This base configuration is intended for applications that use separate braking and expansion modules when those functions are needed.
