RS51.1-4G-003-V-NN-FW

The RS51.1-4G-003-V-NN-FW from Bosch Rexroth Indramat belongs to the RD 500 Drive Controllers series and is engineered for high-performance applications such as high-speed grinding spindles. This drive control device operates on a nominal connecting voltage of 3×380–480 V AC with a tolerance of ±10% and delivers a rated power output of 3 kVA. Its primary function is to regulate spindle speed and torque in precision machining operations, ensuring consistent performance under demanding conditions.

Incorporating advanced control techniques, the RS51.1-4G-003-V-NN-FW features U/f curve control for smooth acceleration and deceleration profiles. It is classified under design code 1 and supports an output frequency range from 0 Hz to 3,000 Hz, providing flexible speed management. The drive control device includes a built-in brake chopper and resistor, enabling rapid energy dissipation during braking events. This combination of specifications makes the unit highly adaptable to variable load scenarios common in modern machine tools.

Beyond its core performance metrics, this unit supports both induction and synchronous motors and fully complies with EMC guidelines for noise emission and immunity. A detachable operator panel with a copy function simplifies parameterization and field updates, while the integrated type plate displays input/output voltage, current, and frequency ratings for clear identification. The firmware is supplied as a separate subitem, and the device is designated as size class J, with a total weight of 20 kg. Designed for cabinet installation, this drive control device carries a one-year global warranty, enhancing system reliability and reducing downtime in industrial environments.
