Product Description

The RD 500 is a highly versatile drive system designed and manufactured by Bosch Rexroth for different synchronous and induction motors. It is a universal, three-phase drive system created with a modular concept that allows it to be adapted to suit user-specific drive applications using modules. Components of this system include AC drive converters like those in the RD 51 series. Their typical applications include chemical and process technology, food packaging machines, and hoist and conveyor technology.

The RD51.1-4N-055-L-V1-FW is a model of converters in Bosch Rexroth’s RD 500 drive system that uses the U/f curve control method for motion control. It works with a nominal three-phase AC connecting voltage that ranges from 380V to 480V with a tolerance of ±10%. Its cooling is done by forced air cooling, and it has a cooling air requirement of 0.4m³/s. It belongs to Size Class D and has an IP 20 Ingress Protection rating according to EN 60529, which means that it cannot be damaged due to the entry of external solid bodies with diameters that exceed 12mm. These include fingers and any other similar objects.

The power rating of the RD51.1-4N-055-L-V1-FW is 55kW, and it permits its operation at varying magnitudes of pulse modulation frequencies, including 4kHz, 8kHz, and 12kHz. It is equipped with an additional 24V standby power supply which ensures that the control devices can still be operated when no line supply voltage is connected to the converter. Some of the operations that this standby power supply can do are the parameterization, reading, and writing into data sets and the sustained operation of field buses. This product can be shipped globally with a one year warranty period from Wake Industrial.
