Product Description

Drive and motion control units designed and manufactured by Bosch Rexroth display significant features that distinguish them from others on the market. They include a high degree of flexibility, user-friendly configuration, and high efficiency. The RD 500 drive system is built with all these integrated into its diverse components. These include AC drive converters, inverters for DC supply, and rectifier and supply modules. As part of a modular system, they can be ordered separately or with other components wired in the system. Typical applications where the RD 500 and its components can be used are machine tools, hoist and conveyor technology, handling and assembly systems, and foodstuff and packing machines.

The RD51.1-7N-018-L-NN-FW is an inverter unit control device in the RD 500 system that adopts the U/f curve control method. The required connecting voltage range for its operation is a DC voltage from 530 V to 670 V with a +/- 10% allowance. Its power rating is 18.5 kW, and its output frequency varies up to 1400 Hz, depending on the pulse frequency at which it is operated. This device belongs to Size Class B and has an IP 20 Ingress Protection rating according to EN 60529 with its connected plug. This means that it cannot be damaged by the entry of solid extrinsic objects larger than 12 mm.

The heat dissipation technique used by the RD51.1-7N-018-L-NN-FW is forced air cooling, and it has a cooling air requirement of 0.05 m³/s. It can be used with firmware, but this has to be purchased as a separate sub-item. For its continuous optimal operation, it should be operated at ambient temperature between 0^o C and 40^o C and a maximum relative humidity of 90 %. This product can be shipped globally with a one year warranty period from Wake Industrial.
