The R911200573 (RD51.1-4N-090-L-NN-FW) is a Rexroth Indramat drive controller engineered for controlling synchronous and induction motors in industrial environments. It employs U/f curve control for precise motor management and features a modular architecture suitable for systems such as textile machinery, food processing equipment, assembly automation, and robotics. The module includes a control panel for real-time monitoring and input, as well as an integral fan and heatsink to manage thermal conditions through forced air cooling, particularly at rated power levels of 90 kW and above. Installation should be carried out by qualified personnel, maintaining a clearance of approximately 80 mm for effective heat dissipation. The unit operates at a nominal input voltage of 3 x AC 380 to 480 V (±10%). The firmware module is not included and must be specified separately. Operating efficiency is typically 90 percent under normal conditions. No additional functions or brake chopper are integrated into this configuration.
