Core Functions

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

2. Forward‑acting control logic, matched with proportional electric/hydraulic actuators.

3. Built‑in startup ramp, actuator stroke limit, load rejection protection, overspeed test and torque limiting functions.

4. Accepts 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.
