3. Product Specifications & Features
3.1 Core Specifications
The REXROTH DKC02.3-100-7-FW is optimized for mid-power precision control, with 7.5 kW continuous output power and 10 A continuous current perfectly matching the demands of medium-load automation tasks (e.g., CNC milling machine axes). Its 30 A peak current capability handles sudden load surges (e.g., robotic arm acceleration) without performance degradation, ensuring operational stability.
Support for multiple feedback types (incremental/absolute encoders) enables compatibility with a wide range of Rexroth servo motors, while multi-protocol communication (PROFINET, EtherCAT) facilitates integration with modern PLCs and motion controllers. The 3U rack-mount design fits standard industrial control cabinets, simplifying system layout and maintenance.
3.2 Key Features
-
Triple Control Modes: Seamless switching between position, speed, and torque control adapts to diverse application needs (e.g., position control for CNC, torque control for material handling).
-
High Dynamic Response: Adaptive control algorithms and 30 A peak current ensure fast response to load changes, reducing positioning errors.
