380V 440V Variable Frequency Inverter 15KW 20HP For 3 Phase Motor

380V 440V Variable Frequency Inverter 15KW 20HP For 3 Phase Motor

Instruction of frequency inverter

In the ST310 series, the DSP dual-core professional control motor chip offers the international leading
V/F control algorithm, allowing real high-precision flux linkage vector torque control.
In high-speed control accuracy, fast torque response, and low-frequency high-performance, it is widely used.
Customer applications can benefit from the integration of torque control, speed control, and position control.

Software design of frequency inverter

1. For control, the maximum frequency is 3000Hz
2. In order to prevent the impact of hardware protection components, wave-by-wave current limit algorithms
are the first line of defense when loading current.
3. There are four conventional overload capacities: 130%, 150%, 180%, 18%, and 20% at 0.5s
4. The speed tracking startup mode contains a minimal impact on current and voltage, as well as accurate tracking speed
5. Four-time fault record: information about current, voltage, and temperature are recorded during fault detection of
frequency converters, which facilitates fault analysis.
6. A user can copy and back up an entire group of parameters through the panel, providing a convenient way to
debug multiple devices at once.
7. The carrier frequency is 0.7 kHz * 16 kHz.
8. The carrier frequency is 0.7khz~16khz. Under conditions of small temperature rises of frequency conversion,
carrier frequency can be automatically adjusted in line with frequency conversion temperature and operating
frequency to ensure reliable operation
9. Protecting against temperature: temperature detection module, setting temperature of overheat alarms on
frequency converters, setting a default fan to start following temperature, greatly extending service life.
10. It supports up to 16 speeds at a time.
