Product Description:
The RR52.1-7N-007-P-V1-FW is a drive controller from Bosch Rexroth Indramat within the RD 500 Drive Controllers series. As a modular inverter stage, it converts a stabilized DC link into three-phase output for induction or synchronous motors used in process lines, conveyors, and machine tools. By regulating torque and speed, the device supports coordinated motion and energy-efficient operation in automated material-handling and manufacturing systems. Because it operates from a shared DC source, it fits installations where power conversion and motor control are separated into dedicated modules.
Core motor regulation is executed through field-oriented vector control, allowing independent adjustment of flux and torque for rapid starts and accurate speed holding. The controller accepts a 530 to 670 V input range, matching the DC bus voltage supplied by upstream rectifiers. Within this window, it delivers 7.5 kW rated power, making it suitable for medium-sized pumps, extruders, and similar driven equipment. Thermal energy produced during switching events is released through a heat dissipation panel, which provides passive cooling when the cabinet layout supports it. During deceleration, the unit is supplied without a built-in brake chopper, so braking energy must be handled by the external DC link or by a resistor located in the supply section.
The module is a design generation 1 unit and uses an inverter DC supply rather than direct mains input. This arrangement suits RD 500 systems that distribute a common DC bus to multiple inverter sections and separate the rectifier function from the motor-control stage. Control electronics remain active from 24 V external standby power, so parameter memory and fieldbus communication stay available while the main DC link is de-energized. Standby power also allows diagnostic access when the power section is inactive. The required firmware must be ordered separately, so the controller can be equipped with the software package needed for the intended application.
