Core Functions

1. Precise closed‑loop speed control to maintain stable frequency under load changes

2. Direct PWM driving for Woodward fuel‑control actuators

3. Built‑in overspeed protection, self‑diagnosis and alarm output

4. Isochronous mode for single‑unit operation; droop mode for parallel gensets

5. Remote speed setting via 4‑20 mA analog input

6. Parameter tuning by dedicated Woodward PC configuration software
