Core Functions

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

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

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

4. Forward‑acting control logic, matches proportional electric/hydraulic actuators.

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