Core Functions

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

2. Built‑in automatic synchronizer for precise frequency, phase and voltage matching before grid connection

3. High‑precision PID closed‑loop speed/load control, with critical speed avoidance, valve limit and startup protection

4. Overspeed monitoring, real‑time self‑diagnosis and multi‑channel fault relay alarm output

5. 4‑20 mA remote setpoint input, compatible with upper‑level DCS/PLC linkage

6. Parameter configuration, online tuning and real‑time monitoring via dedicated Woodward software
