22KW VFD 220V 380V 480V Variable Frequency Drive 3 Phase Motor
Inverter
Instruction of frequency inverter
Basically, the ST310 series is a three-phase asynchronous
motor-controlled inverter with high performance. AC motor power
control device that changes the frequency, voltage, and current of
the motor's working power source. With a high frequency, low
torque, high rotation speed, and stable acceleration and
deceleration, it has excellent overload capacity. Featured in
stable performance and multiple protection functions, the ST310
series offers a wide range of features. Wide voltage range of
220V-480V, convenient for use in many countries, including the
United States, Europe, Asia, South America, and many others.
Software design of frequency inverter
1. Mode of control: V/F (open loop vector control and closed-loop
vector control are in development)
2. The maximum frequency allowed for control is 3000Hz
3. The wave-by-wave current limitation algorithm is the first line
of defense when loading current, to prevent hardware protection
components from being impacted by current loading.
4. It is capable of undergoing conventional overloads of 130%,
150%, 180%, and 200% of 0.5s
5. The speed tracking feature can be launched quickly, has a small
impact on current and voltage, and is accurate
6. There is four times fault record, which records the current,
voltage, and temperature of the frequency converter, which
facilitates fault analysis of the fault process.
7. A parameter copying and backup feature are available for the
panel, which allows for the convenient debugging of multiple
devices on the same panel.
8. An average carrier frequency of 0.7kHz*16kHz is used. Under
small temperature rises in frequency conversion, the carrier
frequency can automatically adjust according to frequency
conversion temperature and operating frequency.
9. Temperature protection: temperature detection module, frequency
converter overheat alarm, flexible starting, temperature-driven
fan.
10. Multi-speed: Supports a maximum of 16 speeds.
