The R911200492 (RD51.1-4N-018-L-D1-FW) is a durable digital drive unit belonging to the Bosch Rexroth RD51 series. It provides a motor output of 18.5 kW at 4 kHz and 15 kW at 8 kHz. The output frequency range extends from 0 to 250 Hz at 4 kHz and 0 to 500 Hz at 8 kHz. Furthermore, it offers varied peak current outputs at 4 kHz and 8 kHz for 60 seconds, 1 second, and 0.5 seconds. Encased in an IP20 rated housing, it is built to withstand ambient temperatures of 0 to 40 degrees Celsius. This unit requires forced air cooling, with a minimum air flow of 0.03 cubic meters per second, and operates on an AC input between 380 to 480 volts. It includes additional functionality with connections for RZC01.1-XT, 24 Volt standby power, and NAMUR terminal strips. However, firmware must be purchased separately. Proper operation and maintenance need to be carried out by licensed personnel. The product comes with a one-year global warranty from Indramat USA.
