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:Motor a speed, the inverter will burn what is going on, the inverter is a large yuan
Inverters Have not heard of it! East yuan heard. The inverter is most likely to be damaged by the motor is running suddenly grounded, the possibility of frying the module more than eighty percent, since a little better brand will blow up! Overload, overcurrent, short circuit, lack of phase caused by damage to the inverter, then the quality of the inverter is so good, and indeed the basic functions of these inverter protection.
Q:How to make the motor speed (control speed), can not use frequency
If you use AC asynchronous motor speed control in three ways: 1 / variable speed control. By changing the motor stator pole pairs to speed, not the linear speed for the sub-file speed, the motor structure and electrical control more complex. 2 / electromagnetic speed control. Driven by the magnet magnet, the electromagnetic coil through the variable size of the DC to speed, for the linear speed, but a waste of energy 3 / frequency control. Through the inverter speed, stepless speed regulation, speed control effect is good, but one-time investment. If the DC motor speed is to change the armature or the excitation coil voltage to achieve speed. Application in the relatively high demand, a one-time investment is relatively large
Q:How to view your own laptop power adapter is how much tile?
1, the power adapter has a logo, you can find their own look, close to the paper or direct letterpress printed with the voltage, current and power. If there is no write power, the direct voltage multiplied by the current is the maximum power. 2, if the power adapter only identifies the output voltage is 20V, the output current is 4.5A, then we formula W (power) = V (voltage) xI (current) to calculate. Calculate the formula with a power to know the output power is 20 × 4.5 = 90W.
Q:Inverter with 2.2KW 6 pole motor. 1 minute 8 times reversing often burn the motor, how to solve. For the 2 pole 4KW motor is the same.
1. Change to servo drive and servo motor. Should be frequent no problem. 2. Or in the machinery to find a way to let it repeatedly change.
Q:The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
1. submersible pumps are generally the problem, far away from the reflection voltage, the pump insulation breakdown, in particular, to better pump. 2. Distance away, the inverter and pump connection thicker. 3. Then on the output filter.
Q:Variable frequency conversion frequency difference characteristics based on,
Frequency conversion is better, you can smoothly change the synchronous speed. Change the difference is relatively poor, also known as "energy consumption slip" speed. Synchronous speed unchanged, the slip rate has changed, so the speed changed.
Q:What are the types of power adapter used in notebooks?
The regulator wants the laptop adapter to not waste energy or add harmonics to the electricity lines. The first factor is that the adapter should plug the plug without any load, and it should be as small as possible to absorb power (standby). People are accustomed to the laptop adapter inserted in the socket, but not connected to the computer, the request can prevent the loss of this situation. The second factor is the recent requirement that it requires a specific average power efficiency at different load conditions (25%, 50%, 75%, and 100%) and is implemented by the global regulatory agencies in order to facilitate compliance with the specification And reduce overhead costs. Finally, the European and Japanese mandated reduction harmonics requirements have been applied to laptop power adapters because they have exceeded these standard specifications for the 75 W input power threshold. In a sense, the mobile / universal features of the laptop adapter make it the first mass production power product subject to the IEC1000-3-2 specification.
Q:The motor is 2 pole with the inverter frequency to 50hz why the speed is only 1500 rpm
Hello, poles (a pair of pole) motor, the theoretical speed of 50 rpm when the theoretical speed of 3000 r / min, if the display shows only 1500 rpm, it is possible to have a motor shaft speed or speed device Yeah, gear ratio of 2 to 1 ,
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:Laptop power adapter output voltage is not the same as the current? What's the effect?
so this replacement is generally feasible in the general use , But the remaining power supply power margin is very small, once your books took a lot of peripherals, such as two usb hard drive, and then cpu full speed operation, and then a base, the above to drive a full speed to read the disk, plus While charging the battery, it is estimated that the danger, and at any time to touch your power is not already already boiled eggs. 72w more than the 56w adapter 16w is to cope with this situation. So it is best not to use a small current instead of high current power supply
