Core Functions

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

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

3. Supports 4‑20 mA analog remote speed/load setpoint input for external DCS/PLC control.

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

5. RS‑485 Modbus‑RTU communication for system monitoring and parameter tuning.
