The R911203478 (RD51.1-5N-037-W-V1-FW) is a Bosch Rexroth vector control converter designed for 3-phase drive applications. It features a 37 kW rated motor output and operates with a nominal connecting voltage of 3 x AC 500 V (±10%). The device incorporates a start inhibitor to prevent unintended motor startup and initiates a self-test after power-on, disabling the main contactor and power section if a fault occurs, with diagnostic information shown on the operator panel. The unit uses liquid cooling, measures 530 x 180 mm, weighs 28 kg, and supports an output frequency of 0 Hz to 250 Hz. Compliance with EN 55011 and EN 61800-3 (A1 level) is observed. Operation requires a minimum steady-state current of one-third the rated motor current. Additional features include support for a 24 V standby power supply, external connection, copy function for commissioning multiple converters, C size classification, U/f curve control, and a modular 22.5 mm grid design for stacking. The model does not include a built-in brake chopper and the firmware is factory assigned.
