Introduction of SVF-G7 Series High-performance Vector General-purpose Frequency Inverter

1. Voltage class: 380V

2. Range of power: 0.4KW~450KW

3. Stable and reliable Control Mode

(1) VF control: Multiple curve could been chosen, Linear V/F curve, 2.0 times power drop torque V/F curve, custom V/F percentage(can realize manual energy saving control), multipoint VF curve. This apply to the situation that one frequency inverter drives multiple motors, such as fan, water pump, engraving machine, injection molding machine etc.

(2) Open-loop vector control: Steady speed with high precision, wide range of speed governing, as the speed ratio is 1:200 and 180% rated torque could be output in 0.5Hz. Good dynamic performance.

Open-loop vector is suitable for high-Performance universal occasions such as machine tools, centrifuges, cranes and handling equipment, rolling mill and other loads.

(3) Torque control: Fast torque response,<20ms, precision torque: <5%, applied to winding, drawing and other occasions.

Q:How does the spindle drive system of the inverter realize the positive and negative control of the main pole?: The general inverter has an external terminal control and communication control two modes optional, select one of them can be completed ah

Q:How does the variable frequency motor output torque at very low frequencies?: 1, to improve the slip of the inverter compensation coefficient 2, to improve the continuous lifting coefficient of the inverter, but the coefficient is too high there will be overcurrent. 3, with no sensor vector control can increase the motor output torque or encoder with the vector control can make the motor at low frequency to achieve the rated output torque.

Q:Is the motor having a variable frequency motor and a variable voltage motor?: Have. 2, variable speed control; 3, electromagnetic speed; 4, variable speed control; 5, variable resistance speed control. Household fans are variable speed control. In addition, the DC motor can also use variable voltage to speed.

Q:ASUS notebook power adapter can be universal? is it?: Yes, see the same parameters as the interface on the line

Q:Can different brands of laptop power adapters be generic?: Power adapter can not use, the key to see two factors. First, the interface must first be the same interface or can not use. Second, the output current, the output current must be strictly consistent, otherwise it would be very dangerous, the laptop overload of the current is very fragile. The final output voltage I personally think can have a difference of type 5V. Because the battery on the voltage requirements up and down can have 5V floating. I have also used a high 5V adapter, has been no problem, but this is just my personal view. Strictly the same as the best. Oh, for reference only! Since you can plug in the normal use, indicating that the interface is consistent, and the output voltage and current are the same. Then I can responsibly tell you, rest assured to use it, there will be no problem.

Q:What is the output voltage of the laptop power adapter?: Laptop power adapter output voltage, different brands may be different. Adapter output voltage is not a unified standard, different models are not the same notebook. The output voltage between 12V to 20V, 19V, 20V more.

Q:Pump frequency converter instantaneous restart and restart the problem: Inverter speed: Based on the advantages of speed control, energy saving and reliable operation, the frequency converter has gradually replaced the traditional variable speed, electromagnetic speed and voltage regulation. In the introduction of PWM flux vector control of the inverter a few years later, the end of 1998 and the emergence of DTC control technology inverter. ABB's ACS600 series is the first generation of DTC technology using the inverter, it can open the ring speed and torque for accurate control, and dynamic and static indicators have been better than PWM closed-loop control indicators. Direct torque control to measure motor current and DC voltage as input to the adaptive motor model. The model produces a set of precise torque and flux actual values ??every 25μs. The torque comparator and flux comparator compare the actual values ??of torque and flux with the reference values ??for torque and flux to Determine the optimal switch position. It can be seen that it is through the torque and magnetic flux measurement, instantly adjust the inverter circuit switching state, and then adjust the motor torque and magnetic flux, in order to achieve the purpose of precise control.

Q:What is the single axis of the inverter and multi-axis applications: Inverter is mainly used for AC motor (asynchronous motor or synchronous motor) speed adjustment, is recognized as the AC motor the best and most promising speed control program, in addition to excellent speed performance, the inverter is also significant Energy-saving effect, is the enterprise technological transformation and product upgrading of the ideal speed control device. Since the introduction of China since the 80s of last century, the frequency converter as energy-saving applications and speed of process control more and more important automation equipment, has been rapid development and wide application.

Q:How to choose the inverter: Look at the motor seat size is 7.5kw it, this model of the inverter manufacturers a lot of production, and are built-in brake unit, so in the function which are the same It is important that the inverter life, stability, price comprehensive consideration Mitsubishi, Panasonic, LG, Emerson, Yaskawa, Siemens and so on

Q:Inverter principle eff23: According to the use of classification, can be divided into general-purpose inverter, high-performance dedicated inverter, high-frequency inverter, single-phase inverter and three-phase inverter. VVVF: change the voltage, change the frequency CVCF: constant voltage, constant frequency. The AC power supply used by each country, whether it is for home use or for the factory, has a voltage and frequency of 400V / 50Hz or 200V / 60Hz (50Hz), and so on. In general, a device in which an alternating current having a constant voltage and frequency is converted into a voltage or a variable frequency alternating current is referred to as a "inverter". In order to produce a variable voltage and frequency, the device first converts the alternating current of the power supply into direct current (DC). For the motor control of the inverter, both can change the voltage, but also can change the frequency. Inverter control mode
