Core Functions

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

2. Direct PWM driving for Woodward fuel‑control actuators

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

4. Supports isochronous control for standalone gensets and droop control for parallel‑running units

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

6. Parameter configuration through dedicated Woodward PC tuning software
