The R911200877 (RD52.1-7N-045-L-LV-FW) is an inverter-based drive controller from the Bosch Rexroth RD500 series, designed with a modular architecture and rear-cooled power sections for thermal management. It integrates radio interference suppression filters and a line reactor to reduce harmonics in the supply. This unit delivers a rated motor output of 45 kW, supports DC input voltages from 530 to 670 V, and operates without an integrated brake chopper. The controller features a 4-line graphical display for monitoring, weighs 22 kg, and has an IP20 protection rating. Operation requires forced air cooling with an airflow of 0.2 m³/s, maintaining an ambient temperature of 0–40°C.
