Core Functions

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

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

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

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

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