Core Functions

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

2. Direct PWM drive 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 tuning via dedicated Woodward PC configuration software
