Technical Architecture & Functional Positioning
The HNC100 occupies the motion control layer in hydraulic automation systems, bridging PLC supervisory commands and field-level proportional valves. It executes real-time closed-loop algorithms independently, offloading complex hydraulic control from the main PLC to achieve higher performance and determinism.
The architecture centers on a high-speed DSP processor handling multiple control loops simultaneously. Built-in hydraulic-specific functions include valve linearization, overlap compensation, and adaptive gain scheduling, which directly address non-linearities inherent in hydraulic actuators. Switchable control modes allow seamless transitions between position, velocity, and force without external logic, simplifying application programming. The modular I/O structure supports direct connection of transducers, eliminating intermediate signal conditioning in many cases.
Engineering value is particularly evident in applications requiring sub-millimeter accuracy or rapid force changes. The fast cycle time and dedicated hydraulic algorithms deliver superior dynamic response compared to PLC-based control, reducing overshoot and settling time. In multi-axis setups, synchronized operation via fieldbus minimizes mechanical stress on coupled loads. This design philosophy solves common challenges like drift in long-stroke cylinders or pressure spikes in injection processes, contributing to longer component life and consistent product quality.
