Core Functions

1. Dual control modes: isochronous (zero‑droop) for standalone constant‑speed operation; droop control for multi‑unit parallel load sharing

2. High‑precision PID closed‑loop regulation, supports critical speed skip, valve stroke limit, startup fuel limit and interlock protection

3. Real‑time self‑diagnosis, overspeed protection, fault logging and relay alarm output

4. 4‑20 mA analog remote setpoint input, compatible with DCS/PLC upper‑level system linkage

5. Supports unit synchronization, ramp‑up/down control, auxiliary interlock and safety protection

6. Local HMI parameter setting + dedicated Woodward software online tuning & real‑time monitoring
