The R911332789 (HCS04.2E-W0790-N-04-DNNN) is an HCS series drive controller engineered by Bosch Rexroth for industrial use. It features an enclosed DC bus choke, a 900 A mains fuse, supports a connection voltage range of 380–480 V, and delivers a maximum current of 790 A. Designed for 4-quadrant operation, it manages DC bus voltage by dissipating excess energy through a braking resistor, converting it to thermal energy. This unit is internally cooled via an integrated blower and should be installed with copper cables compliant with UL/CSA standards. It conforms to EMC immunity requirements specified by EN 61800-3. The operating environment must be moisture-free and the controller must be allowed to cool down before handling. Integration with non-manufacturer components is not recommended. Power must be removed prior to dismounting.
