Core Functions

1. Dual control modes: isochronous (zero‑droop) for standalone unit 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. Independent overspeed monitoring, real‑time self‑diagnosis, fault logging and multi‑channel relay alarm output

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

5. Supports unit synchronization, ramp‑up/down control, extraction/admission regulation and safety interlock functions

6. Local HMI parameter configuration + dedicated Woodward software for online tuning and real‑time monitoring
