Core Functions

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

2. Supports 4‑20mA / 1‑5 VDC analog remote speed/load setpoint input for external system control.

3. Built‑in fuel limiting, soft load transfer, load rejection protection, overspeed test and speed trim adjustment functions.

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

5. RS‑485 Modbus‑RTU communication for DCS/PLC system integration.
