Product Description

The RD51.1-4N-001-L-V1-P1-NN-FW is a U/f curve control drive system in the RD 500 series, by Rexroth Indramat. It is a Converter (AC) unit and has a type-1 design. The nominal voltage of this system has an admissible range of 380 – 480 Volts at +/- 10 %. At a pulse (PWM) frequency of 4 kHz, the operating frequency range of the RD51.1-4N-001-L-V1-P1-NN-FW is 0 – 250 Hz. At 8 kHz PWM frequency, output frequency has a range of 0 – 500 Hz. This unit aligns with the indications of the 3K3 climatic classification.

The RD51.1-4N-001-L-V1-P1-NN-FW comes embedded with a PROFIBUS-DP communication interface, and its sophisticated design contributes to its efficient control of electric motors and adequate monitoring of their operations. Furthermore, its renowned areas of use include assembly systems, machine tools, packing machines, process technology, etc. It is not suitable for use in conditions where the temperature is at the extreme or fluctuates haphazardly. Also, this equipment is not recommended for use under water.

The RD51.1-4N-001-L-V1-P1-NN-FW converter unit does not have an integrated brake chopper but features a 24 Volts external standby power unit. The suitable cooling mechanism for this equipment is the forced air-cooling method with a power rating ≤ 110 kW. Its noise immunity/radio interference suppression with RZF line filter is classified A1, according to the EN 61800 – 3 standards. In addition, the Ingress Protection class of the RD51.1-4N-001-L-V1-P1-NN-FW is IP 20 and class size is A. Generally, RD 500 drive control systems are regarded as high-voltage equipment, and must only be operated, maintained and commissioned by professional and certified technicians at all times to avoid malfunction, damage to parts or the overall system and health-related hazards. This product can be shipped globally with a one year warranty period from Wake Industrial.
