15KW 20HP VFD Single Phase To Three Phase Frequency Inverter
Instruction of frequency inverter
The ST310 series is an inverter for high-performance v/f control primarily for three-phase asynchronous motors.
Controls the AC motor with its working power supply by varying its frequency, voltage, and current. The motor exhibits
several characteristics, such as a high-speed rotation, high torque, high acceleration and deceleration, and a high capacity
for overloading. Multi-protection features and stable performance are the hallmarks of the ST310 series.
The wide voltage design, which is in compliance with international requirements, including the United States, Europe, Asia,
South America, and other countries, make the products widely used in many fields across the globe.
Software design of frequency inverter
1. Currently available is the V/F control mode (open-loop vector control and closed-loop vector control are under development).
2. For control, a maximum frequency of 3000Hz is allowed
3. The wave-by-wave current limit algorithm is the first line of defense against hardware protection component impact.
4. A conventional overload capacity of 150% in 60 seconds, 180% in 10 seconds, and 200% in 0.5 second
5. With speed tracking, small current and voltage impacts, and accurate tracking speeds are possible
6. The frequency converter has a four-time fault record that records currents, voltages, and temperatures during the fault process,
aiding in the diagnosis of faults
7. A group of parameter values can be copied and backed up in the panel, making debugging multiple devices convenient.
8. A carrier frequency of 0.7 to 16 kHz is used. It is possible to automatically adjust carrier frequency at the same frequency
as the frequency conversion temperature and operating frequency to ensure reliable operation under conditions of a small
temperature rise.
9. It includes a temperature detection module, an overheat alarm temperature setting, and a flexible start system, which extends
the life of the fan by following the temperature.
10. It supports a maximum of 16 speeds.
