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: 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: How does the laptop's power adapter open
First put the power adapter on a clean desktop, with electric knife to the upper and lower cover along the edge of the gap slowly pry open, you can also use the hammer gently tapping the back of the electric knife, so you can turn on the laptop power adapter
Q: Inverter signal line analog 4-20mA connection positive and negative can be reversed?
Theoretically reverse seems to be possible, but the operation will be normal, you can do experiments to try what is the result. Various manufacturers of the inverter may be the treatment of this problem will be different.
Q: What are the differences and links between the soft starters and the frequency converters, and their respective principles and uses?
The soft starter is activated by adjusting the voltage and current, and the frequency converter starts the motor by changing the frequency of the power supply. The soft starter can theoretically smooth and gradually start the motor to the maximum speed. No impact current (ordinary start-up current is 6-7 times the rated current) The inverter is best suited for tap water and fans, etc. The soft starter is not suitable for everything except for heavy load start.
Q: Lenovo laptop power adapter side of the feet which is positive
Lenovo laptop power adapter side of the mouth there are clear signs positive and negative, N on behalf of the positive, L on behalf of the negative, it is recommended to carefully look at that you can know.
Q: Notebook plug in the power adapter lights, but can not open the machine
Put the board under the re-installed, try and then boot. Asked: This is the case of removal, with the battery can boot answer: Then put the battery on the computer, and then use the power splitter to see if you can. If not I do not know, is the computer question to ask: This can be
Q: What is the characteristic of the variable pole speed method?
Third, cascade speed control method Cascade speed regulation refers to the winding motor in the rotor loop into the adjustable additional potential to change the motor slip, to speed control purposes. Most of the slip power is absorbed by the additional potential in series, and the additional device is used to return the absorbed slip power to the grid or to convert the energy. According to the slip power absorption and utilization, cascade speed can be divided into motor cascade speed, mechanical cascade speed control and thyristor cascade speed form, the use of thyristor cascade speed, which features: The process of the slip loss back to the grid or production machinery, the higher efficiency; device capacity and speed range is proportional to the investment province, for speed range in the rated speed of 70% -90% of the production machinery; Device failure can be switched to full speed operation, to avoid shutdown; thyristor cascade speed power factor is low, the greater the impact of harmonics. This method is suitable for use in wind turbines, water pumps and rolling mills, mine hoists, extruders. Fourth, winding motor rotor series resistance speed control method Winding asynchronous motor rotor series into the additional resistance, so that the motor slip increase, the motor running at a lower speed. The greater the resistance of the series, the lower the motor speed. This method is simple and easy to control, but the slip power is consumed in the form of heat. Is a level of speed, mechanical characteristics of soft.
Q: 400w 6-pole motor should be equipped with much of the inverter?
0.75KW just fine, neither waste the inverter resources, but also to meet the occasional overload. And 0.75KW inverter is the standard model.
Q: Delta inverter reported CE4 reasons? Casually asked how many kinds of CE under a total
Which model ah, CE alarm, it should be communication failure. CE4, it seems that should be written to the read-only address. You follow the inverter model, to the Delta website to download the corresponding manual, there are fault alarm instructions.
Q: 380V 2 pole motor can use the inverter?
Of course, the stator winding can be connected with concentric While enameled wire to be better, preferably 180 degrees or 155, and even dedicated enameled wire
