The R911200905 (RD51.1-5N-315-R-V1-FW) is a Bosch Rexroth drive control device designed for precise and efficient operation in controlled environments. It operates with a nominal connecting voltage of 3 x 500 VAC (±10%) and supports pulse frequencies of 4 kHz and 8 kHz. The rated power output is 315 kW, and it requires a cooling air flow of 0.8 m³/s with at least 200 mm clearance for airflow; cooling is achieved via a liquid cooling system equipped with an internal pump (for ratings ≥132 kW). The unit uses AL electrolytic capacitors in the DC link, offering a storage life of up to two years at a maximum of 40°C. Connection is via L1, L2, and L3 supply terminals. The design includes a line filter, heat exchanger, 24 V stand-by power (external), and does not include a built-in brake chopper. Factory-assigned firmware is installed, and servicing should be performed by qualified personnel only.
