Core Functions

1. High‑precision closed‑loop speed control to maintain stable 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 mode for single‑unit gensets and droop mode for parallel‑running units

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

6. Parameter configuration by dedicated Woodward PC tuning software
