Core Functions

1. High‑precision closed‑loop speed control to stabilize frequency under variable‑load conditions

2. Isochronous mode for single‑unit gensets; droop mode for multi‑unit parallel running

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

4. Built‑in overspeed protection, self‑diagnosis and fault alarm outputs

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

6. Parameter tuning and monitoring via dedicated Woodward configuration software
