Core Functions

1. Two control modes: isochronous (constant speed) for single‑unit operation; droop control for parallel gensets.

2. Forward‑acting output logic, matched with standard proportional electric‑hydraulic actuators.

3. PID closed‑loop control with startup ramp, stroke limit, overspeed test and protection functions.

4. Accepts 4‑20 mA remote setpoint signal for speed adjustment, compatible with DCS / PLC.

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