The Bosch Rexroth MPN R911274121 (DKR02.1-W200N-BE32-01-FW) is an industrial controller designed for precise control and monitoring of AC electric motors in applications such as machine tools, handling systems, printing machinery, and robotics. It features an integrated power supply module connecting directly to a three-phase 400–480 V AC mains with a 200 A rated current. The controller supports continuous power outputs of 47 kW at 4 kHz switching frequency and 37 kW at 8 kHz, requiring 120 A and 95 A respectively. Interfaces include SERCOS communication, RS-232 for terminal or PC connection, and H1 status display for diagnostics. The unit incorporates five plug-in slots (U1 and U5 functional), accommodates digital servo and resolver feedback, and utilizes air cooling via a built-in blower. The controller operates within a 0 to +45°C ambient temperature range at altitudes up to 1000 m, with an IP20 protection rating and without a bleeder or brake chopper, featuring a rigid DC bus configuration.
