Core Functions

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

2. Reverse‑acting control logic: actuator fuel increases when output voltage drops, power‑loss fail‑safe to full‑fuel position, compatible with mechanical backup governorsWoodward.

3. PID closed‑loop control with startup ramp, actuator stroke limit, load rejection protection, overspeed test and torque limiting function.

4. Supports 4‑20 mA analog remote setpoint for speed/load adjustment, compatible with DCS/PLC systems.

5. RS‑485 Modbus‑RTU communication for real‑time monitoring and parameter configuration.
