Core Functions

1. High‑precision closed‑loop speed control to keep frequency stable under load fluctuations

2. Isochronous control for single‑unit gensets; droop control for multi‑unit parallel operation

3. Grid synchronization, load distribution, 4‑20 mA / 1‑5 VDC remote setpoint input

4. Overspeed protection, self‑diagnosis and fault alarm output

5. Direct drive for standard Woodward fuel actuators and turbine control valves

6. Parameter configuration, tuning and monitoring via dedicated Woodward software
