Core Functions

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

2. Supports isochronous mode for single‑unit gensets and droop mode for multi‑unit parallel running

3. Grid synchronization, load distribution and remote setpoint via 4‑20 mA / 1‑5 VDC analog inputs

4. Integrated overspeed protection, fault self‑diagnosis and alarm output functions

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

6. Parameter tuning, commissioning and monitoring with dedicated Woodward PC software
