Product Description:
The RD51.1-4N-001-P-NN-FW is a drive controller manufactured by Bosch Rexroth Indramat for the RD 500 Drive Controllers series. It is intended for speed control of three-phase induction motors in material-handling systems, pumps, and ventilation equipment, where the drive forms the power stage between the mains supply and the motor. In normal operation, the controller adjusts output frequency and voltage so connected motors can run at the speed required by the process. This makes the unit suitable for applications that need steady motor control without the complexity of closed-loop servo regulation.
The power section uses a Converter 3 x AC front end and accepts line voltages from 380 to 480 V. Its allowable input variation is ±10%, which supports operation on industrial power systems with moderate voltage fluctuation. Motor behavior is regulated through U/f curve control, which maintains the relationship between voltage and frequency for straightforward open-loop speed adjustment. An integrated mains filter reduces conducted electrical noise on the supply side and helps simplify cabinet installation. The unit is supplied without a built-in brake chopper, so braking energy must be handled by an external chopper arrangement when the application requires dynamic deceleration.
Thermal management is handled through a heat dissipation panel intended for conduction cooling through a metal mounting surface. This arrangement is commonly used in cabinets where heat must be transferred to the backplane instead of removed by internal airflow alone. The cooling arrangement is suitable for frame sizes up to 18.5 kW, which helps the drive fit installations with limited cabinet space. The unit is built as design generation 1, so compatible accessories and matching control software should be selected for that generation. The controller is supplied as base hardware, and any required application-specific functions must be selected separately.
