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 multi‑dynamic control: manifold air pressure (MAP) limiter, torque limiter, low‑speed sensing, soft load transfer, load rejection protection, auto idle‑rated switching.

3. Adaptive speed sensing algorithm, supports remote speed/load reference adjustment and overspeed test function.

4. Dual independent serial communication ports (RS‑232/RS‑485 Modbus‑RTU), redundant Ethernet communication for high‑reliability networking.

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