Product Description

The RD51.1-4N-004-L-NN-NN-NN-FW by Bosch Rexroth Indramat is an RD51 device with U/F curve control. This unit weighs 6.5 kg, and the power rating is about 4.5 kW. It features a 3-phase system, and its design allows it to efficiently control and monitor induction and synchronous motors. For efficient utilization of the control features of this system, an actuator and sensors may be required. Its typical fields of application include process technology, conveyor systems, assembly and handling systems, etc. Its software and hardware design are flexible and efficiently facilitates app-specific use cases.

The RD51.1-4N-004-L-NN-NN-NN-FW regulates heat by using a forced air-cooling method. Unlike other RD51 Indramat Refu drive variants, it does not have additional functions. Also, its firmware is manufacturer-specified and must be obtained as a different package. The radio interference suppression level or noise immunity of the RD51.1-4N-004-L-NN-NN-NN-FW as per EN 55011 is A1. Additionally, this unit is a 3-phase Alternating Current converter with a ± 10 % voltage tolerance. This variant of the RD51 drive control system does not feature a chopper brake. Also, it has an output frequency range of 0 – 250 Hz. It conforms with the 3K3 environmental category, and its size class is A. Also, this drive control system is IP 20 rated as per DIN IEC 721-3-3.

The flow requirement of the cooling air supplied to the RD51.1-4N-004-L-NN-NN-NN-FW is 0.03 m³/s. All specifications listed for this unit are applicable at a 4 kHz pulse frequency. In addition, the relative humidity (RH) rating is recommended at an upper limit of 90 %. During storage, transportation and operations, condensation and contaminants are prohibited to protect the moisture-sensitive sections of the RD51.1-4N-004-L-NN-NN-NN-FW. This product can be shipped globally with a one year warranty period from Wake Industrial.
