The R911281338 (DKR03.1-W100N-BE56-01-FW) is a BOSCH Rexroth DKR series drive controller engineered for operation of AC motors in environments such as printing and machining. It is configurable via standalone plug-in modules inserted into slots on the controller chassis. The unit features IP20 protection per IEC 529/EN 60529, supports a rated current of 100 A, and is equipped with a SERCOS interface for command input. The controller operates at 50-60 Hz with natural convection and a built-in blower for heat dissipation, typically releasing 1200 W during operation. The device functions optimally between ambient temperatures of 5°C and 45°C, and incorporates digital servo and resolver feedback. There is no internal bleeder or brake chopper; the DC bus is rigid. At least a 5-minute discharge interval is required after shutdown for the internal capacitors.
