The Bosch Rexroth R911201008 (RD51.1-4B-055-L-VY-FW) drive system features a three-phase universal design, ideal for motor control applications. It offers both standalone modules or a fully-wired system for optimal flexibility. The drive system uses forced air cooling with a cooling airflow requirement of 0.4 cubic meters per second, maintaining an optimal temperature range of 0 to 40 degrees Celsius to prevent internal overheating. The three-phase AC input converter incorporates an integrated brake chopper, facilitating better voltage control during energy backfeed into the intermediate circuit. The R911201008 (RD51.1-4B-055-L-VY-FW) offers a peak power of 130 kWh and a continuous power of 33 kWh. Its rated motor output varies from 45 to 55 kWh, depending on the kilohertz. The firmware is available as a separate subposition. This 52-kilogram driver is globally distributable and comes with a one-year warranty from Indramat USA.
