3. Brand History
Woodward, Inc., founded in 1870 and headquartered in Fort Collins, Colorado, USA, is a global leader in energy control systems. The company has a long history of innovation in turbine control, engine management,
and power generation systems.
Woodward products are widely recognized for their reliability and precision in demanding industrial and power generation applications.
4. Applications in Industrial Automation
The 5461-777 plays a critical role in industrial automation and power generation environments:
- Steam Turbine Control: Manages startup, speed regulation, and extraction/admission control of steam turbines.
- Power Generation Systems: Used in power plants to regulate turbine-driven generators for stable frequency and load management.
- Compressor and Pump Drive Control: Ensures precise speed control for turbine-driven compressors and pumps.
- Process Industry Applications: Applied in chemical plants, refineries, and other industries requiring precise turbine operation.
- Safety and Protection Functions: Includes overspeed protection, critical speed avoidance, actuator travel limits, and event logging for operational safety.
4. Compare output function
When the position reaches the set coordinate point during the motion, the motion controller outputs one or more switch values without affecting the
motion process. In AOI flight detection, the comparative output function of the motion controller enables the system to run to the set position and start
CCD rapid imaging without affecting the motion, greatly improving efficiency and image quality. In addition, in laser engraving applications, the function
of the universal motion device of Gu Gao Technology has also been well applied.
5. Probe signal latch function
It can lock the timing of probe signal generation and the position of each motion axis, and its accuracy is only related to the hardware circuit, not affected by
software and system operation inertia. It has good applications in the CCM measurement industry. In addition, more and more OEM manufacturers
hope to integrate their rich industry application experience into motion control systems, and design personalized motion controller functions for different
application scenarios and control objects. Gu Gaoxin Company has developed a universal motion controller application development platform, which
enables the universal motion controller to have a truly object-oriented open control structure and system reconstruction capability. Users can load their
designed control algorithms into the memory of the motion
controller without changing the structural design of the control system, and can reconstruct a special purpose dedicated motion controller.
