Product Description

The Bosch Rexroth RD51.1-4N-005-P-NN-FW is a digital drive controller. It supports Volts per Hertz characteristic control. It is compatible with various synchronous and induction motors. The drive includes a heat dissipation panel for maintenance of ambient temperature. The ideal operating temperature range for the drive unit is 0 to 40 degrees Celsius. The weight of the drive system is 5.5 kilograms. Weight class of the RD51.1-4N-005-P-NN-FW is A. The degree of protection offered by the drive housing is IP20. This indicates protection from solids with 12 millimeter dimensions. The drive housing does not provide protection from liquid ingress. The RD51.1-4N-005-P-NN-FW can be installed inside a cabinet that provides the desired level of environmental protection. The RD51.1-4N-005-P-NN-FW is based on a converter that does not include a brake chopper. The converter is rated for 380 to 480 Volts AC (three-phase) input.

The rated motor output of the RD51.1-4N-005-P-NN-FW at 4 kilohertz pulse frequency is 5.5 kilowatts. The drive can also be operated at 200 to 230 volts AC but in this case the output power drops to 2.8 kilowatts. The overload capability of the drive is 200% for 0.5 seconds duration and 170% for 1 second duration. To reduce the harmonics that are fed back into the line supply the RD51.1-4N-005-P-NN-FW is equipped with a line reactor and interference suppression filters. The drive can be commissioned from either the operator panel or PC based software. Bosch has provided type labels on the RD51.1-4N-005-P-NN-FW drive. These labels include the drive type code, the firmware type code, the device serial number, and current/voltage ratings for the input and output. The information on the label is provided for device identification. This product can be shipped globally with a one year warranty period from Wake Industrial.
