Product Description:

Bosch Rexroth Indramat is a leading producer of automation produced used in industrial applications all over the world. The company, through its efficient production process, combines its decades of manufacturing experience with the latest technology innovations to produce machines that provide long-lasting solutions. The RD51.1-4N-037-L-NN-FW is a drive controller built by this reputable company. It is a compact unit that can be used in various applications, including hoist and conveyor technology, machine tools, chemical and process technology, and foodstuff machines. The design of this product also provides it with a small footprint, allowing for an easy installation in areas with limited installation space. After the delivery of this product, operators are required to install it inside a control cabinet that is able to supplement the IP20 protection provided by the controller housing. The control cabinet should meet at least the IP54 protection class.

The RD51.1-4N-037-L-NN-FW controller is unlike conventional units as it is able to maintain high performance standards with both synchronous and asynchronous motor series. However, the motor used should be from the same manufacturer. Motors connected to this product can produce a power output as high as 37 kilowatts. The supply voltage of the unit is also estimated to be between 530 and 670 volts of direct current.

The RD51.1-4N-037-L-NN-FW requires a rated current of 68 amperes; however, it can operate at increased current as high as 88 amperes for a duration of 60 seconds. The peak power of the motor at this maximum current is estimated to be about 58 kilovolts ampere. The firmware module of this product is not included in its delivery package; however, it is available for shipping to customers who place a separate order for it.
