The R911287848 (DKR04.1-W300N-BT67-01-FW) is a Bosch Rexroth drive controller intended for controlled operation in NC-controlled machine tools and printing machinery. It supports three-phase power supplies rated at 3xAC 400 V to 480 V and can utilize an autotransformer for voltage compatibility as well as an isolating transformer for overvoltage protection. The drive controller is manufactured to IP20 protection requirements per EN 60 529 and is suitable for installation within a cabinet or closed housing compliant with DIN VDE 0160. It employs air cooling via a built-in blower, operates within a temperature range of +5 to +45 °C, and is designed for use at altitudes up to 1000 meters. The unit includes a SERCOS interface for command input, supports digital servo and resolver feedback for motor control, and has a rigid DC bus with no brake chopper. Rated for a nominal current of approximately 300A, the controller is configured as DKR series, line 04, design version 1, and function numeric version 01. Care should be taken during installation to prevent moisture ingress, particularly from heat exchangers.
