Core Features and Advantages
Optimized Fan/Pump Control
Built-in PFC pump control, supporting up to 7 pumps (1+6), with cyclic soft start and switching, suitable for constant pressure water supply/central ventilation.
Override Mode (Fire Mode) for emergency operation of tunnel/subway fans; PID2 can independently control external valves, improving system flexibility.
High Efficiency and Energy Saving
Fluidity optimization technology automatically reduces excitation current under light loads, achieving energy savings of 20%–50% (fan/pump operation).
Controllable cooling fan + random switching frequency distribution reduces noise and improves energy efficiency, suitable for noise-sensitive scenarios.
Reliable and Easy to Use
Multiple protections: overload (1.5 times rated current for 1 minute), overvoltage, undervoltage, short circuit, overheating, grounding fault; electronic thermal relay adapts to different motors.
Standard built-in Modbus RTU, optional PROFIBUS DP/DeviceNet/EtherNet/IP, supporting remote monitoring and system integration.
Fault self-diagnosis and historical record support for rapid location and recovery; long mean time between failures (MTBF); low maintenance cost.
Limitations
Primarily scalar control; lacks closed-loop vector control; dynamic response is slightly inferior to high-performance series such as the ACS880; not suitable for high-precision speed/torque control scenarios.
Protection rating IP21; requires indoor or enclosure installation; outdoor applications require additional protection.
