This drive system, comprising AC drive converters, DC supply inverters, and rectifier modules, is recognized for its performance, resilience, and cost-effectiveness. Specifically, the R911200831 (RD51.1-5B-045-D-DL-FW) utilizes U/f curve control and includes a built-in brake chopper rated at a continuous 27kW power and peak power of 111kW for 1 second.
