The Bosch Rexroth drive controller R911284903 (DKR02.1-W200B-BE79-01-FW) features secure plug-in connections, an H1 display, and a SERCOS command interface for communication and diagnostic functions. It supports digital servo and resolver feedback for motor control, with specialized connectors for signal and control voltages, as well as for motor brake and temperature monitoring. The unit integrates a built-in blower for air cooling and includes two analog measuring outputs, an RS-232 interface, and an S1 reset key. This DKR02.1 series controller offers a rated current of 200A, peak current of 141A, and a noise emission of 68 dBA at 50/60 Hz. The device weighs approximately 49 kg and should be handled using suitable lifting equipment. Strict manufacturer guidelines require approved accessories and ensure that no residual voltage is present before servicing.
