Key Functions

1. Precise closed‑loop speed control, stable frequency output under varying load conditions

2. Direct PWM driving for Woodward fuel‑control actuators

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

4. Supports isochronous (stand‑alone) and droop (parallel gensets) control modes

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

6. Parameter tuning by dedicated Woodward PC configuration software
