RS51.1-4G-050-V-V1-FW

The Bosch Rexroth Indramat RS51.1-4G-050-V-V1-FW is a member of the RD 500 Drive Controllers series, designed by Bosch Rexroth Indramat as a high-performance universal AC drive system. Featuring a Rated Power of 50 kVA and an External 24 V Stand-by Power Supply, this drive unit serves as a robust drive control device for high-speed grinding spindles. With support for the U/f algorithm, it precisely regulates motor speed and torque, making it ideal for demanding industrial applications.

This drive control device operates on a Supply Voltage of 3 × AC 380-480 V and delivers a Continuous Output Power Rating of 41 kVA, with peak power reaching 63 kVA and peak current of 82 A. The unit integrates a built-in Brake Chopper and Brake Resistor (10 Ω with 80 kW peak braking power and 1.2 kW continuous), ensuring rapid and controlled deceleration. Forced air cooling maintains optimal temperature, while the removable operator panel with copy function simplifies commissioning and maintenance. Compliance with the EMC product standard EN 61800-3 is achieved through an integrated interference suppression filter and line reactor, guaranteeing immunity to and reduced emission of electrical noise.

Additional features include a variety of communication interfaces—SERCOS, Interbus S, and Profibus DP—along with peer-to-peer coupling for fast inter-drive communication. The drive’s IP20 rated housing is suited for installation within a protected industrial enclosure and accommodates an ambient operating temperature range of 0 to 40 °C. Weighing approximately 80 kg, the RS51.1-4G-050-V-V1-FW offers a compact footprint with a size class of M. Backed by a one-year warranty, this versatile drive controller ensures enhanced efficiency, reliable operation, and straightforward integration into complex automation systems.
