Product Performance

G2000A5.7ST adopts a 16-bit microprocessor and high-precision A/D converter to achieve precise regulation of motor speed and torque. Under vector control mode, it can maintain high starting torque under low-speed conditions, meeting the starting needs of heavy-load equipment. The built-in adaptive load algorithm can automatically optimize output parameters according to load changes, reducing energy consumption by 10%-20% (compared to fixed-speed drives).

It has comprehensive protection functions, including overvoltage, overcurrent, overload, overheating, motor phase loss, ground fault and locked-rotor protection. When an abnormality is detected, it immediately cuts off the output and triggers an alarm to protect the inverter and motor safety. It supports parameter copying function, and can quickly realize parameter synchronization of multiple devices through USB interface, simplifying the debugging process.

The communication interface supports seamless connection with upper control systems, enabling remote monitoring, parameter configuration and fault diagnosis, with data transmission delay ≤50ms. The compact design saves installation space, multiple installation methods adapt to different on-site layouts, and the automatic start-stop function of the fan further reduces operating noise and energy consumption.
