Core Functions

1. Dual regulation modes: isochronous (zero‑droop) control for constant‑speed standalone operation; droop control for parallel multi‑unit load sharing.

2. Closed‑loop precise speed control, rapid response to load fluctuations, stable speed output.

3. Supports remote speed setting via 4‑20 mA / 1‑5 VDC analog signals, compatible with external computer control systems.

4. Built‑in overspeed/underspeed protection, stall alarm, fault self‑diagnosis and status monitoring.

5. Configurable parameters via serial ports, compatible with handheld programmers and PC commissioning software.

6. Supports multi‑unit parallel synchronization, soft loading/unloading and stable grid‑connected operation.
