Product Description

The RD51.1-4B-030-L-DF-FW is a part of Rexroth Indramat's REFUdrive 500 drive control family. It is a drive control unit of the U/f curve control converter type that employs a Voltage Frequency Control (VFC) mechanism. It is frequently used in applications such as food processing and packaging, machine tools, process and chemical technology, assembly and handling systems, and hoist and conveyor technology. The RD51.1-4B-030-L-DF-FW 's heat dissipation mechanism is aided by forced air cooling. This unit also includes a connection for the RZC01.1-XT to the NAMUR terminal strip.

This unit's power supply module is the RD42 variant, which operates at a three-phase supply voltage of 380–480 Volts and a 50–60 Hz frequency. It is equipped with a converter that incorporates a braking chopper, and its power rating is 30 kW. Due to the "L" type cooling mechanism used in this unit, the minimum distance from heat-sensitive objects must be maintained at 100 mm. The RD51.2-4B-015-L-DF-FW is noise-resistant in accordance with EN 50082-2.

The RD51.1-4B-030-L-DF-FW, like other devices in the RD51.2 series, can be operated with or without a line reactor or EMC filter. Also, the storage ambiance of the unit must be clean, dry, and maintained between -25 and 70 degrees Celsius. Additionally, temperature changes of more than 20K every 60 minutes are prohibited. For optimal performance at the installation location, this unit requires dust-free air, an ambient temperature range of 0 to 40 degrees Celsius, a relative humidity rating of 90 percent, and the absence of aggressive or conductive gases. Before running the RD51.1-4B-030-L-DF-FW, it must be parameterized for the desired application. It can be configured using the powerful RDwin software package from Rexroth Indramat. This product can be shipped globally with a one year warranty period from Wake Industrial.
