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: 3.7KW inverter with 2.2KW 6-pole motor running to see the inverter shows the current is more than 4A, with the amount of clamp to 2.8A
- 2, upstairs brothers to answer the correct, the basic frequency is the following constant speed torque control, load changes little, the current change is not large.
- Q: What parts of the inverter composition
- Frequency control technology is an important development direction of modern power transmission technology, with the development of power electronics technology, AC frequency conversion technology from theory to practice gradually mature. Inverter not only smooth speed, large range, high efficiency, start current is small, smooth operation, and energy saving effect is obvious. Therefore, the exchange frequency control has gradually replaced the traditional traditional slip speed, variable speed control, DC speed control system, more and more widely used in metallurgy, textile, printing and dyeing, smoke machine production lines and buildings, Water supply and other fields. However, due to the environment, the use of life and man-made operation and other factors, affecting the life of the inverter greatly reduced, while the use of a variety of failures have occurred. Here we are on the composition of the inverter and common problems and countermeasures and we discuss. Generally divided into rectifier circuit, flat wave circuit, control circuit, inverter circuit, and so on several major parts.
- Q: What is the number of parameters of the motor frequency of the Siemens inverter?
- Siemens inverter motor pole number parameter code is r0313 motor pole pairs. Note that the number of pole pairs.
- Q: How does the laptop's power adapter open
- Notebook power adapter using the correct method] 1. Try to avoid the use of outdoor or harsh environments to prevent the adapter is exposed or damp. 2. When you are not using the adapter, please unplug the power plug. Because, for a long time the power will let the adapter has been in working condition, will affect the end of life. 3. Although the adapter is a broadband operating voltage, marked from 100V-240V can be, but if the voltage is extremely unstable in the case of use, the same will cause damage to the power adapter.
- Q: Asus notebook power adapter how to open
- Can only be forced to open the pants and other things wrapped around the line on the line suggested that do not casually demolition
- Q: Servo control system can give the inverter signal,
- but want two motor synchronization, it should be impossible, the converter does not reflect so fast, and the speed is not so stable.
- Q: My laptop can not use the power adapter, and can only use the battery, how is it ah,
- 1, laptop power adapter can not be used, first check the power outlet, plug, cable has no virtual state, if you can tell the normal equipment damage. Should be repaired. 2, the laptop battery must be charged through the power adapter or directly for the computer power, the power adapter is not missing, if you have experience can turn on the power adapter to see if the fuse is broken, try to update the fuse can be restored. If the integrated circuit is damaged, only updated.
- Q: What is the difference when using inverter frequency conversion ordinary motor and variable frequency inverter motor
- First of all you have to understand the difference between variable frequency motor and ordinary asynchronous motor. 1, inverter motor cooling fan is not connected with the motor spindle, is independent, the fan rotation from the motor speed, to ensure that the motor cooling.
- Q: Does the inverter set the number of poles to match the number of poles of the motor?
- Variable-frequency (VFD) is the application of frequency conversion technology and microelectronics technology, by changing the motor operating frequency mode to control the AC motor power control equipment. The inverter is mainly composed of rectifier (AC variable DC), filter, inverter (DC variable AC), brake unit, drive unit, detection unit micro-processing unit and so on.
- Q: The inverter flat rate transferred to 29, on the submersible pump to burn the coil ?!
- The following describes the selection of the inverter Note: The inverter selection is mainly driven by the load characteristics and the actual motor current to set, in addition, there are the following precautions. 1, the environment: for some high temperature (higher than 50 degrees), high altitude (more than 1000 meters) of the application, the inverter selection should be appropriate to leave a margin to ensure that the inverter and motor life. 2, distance: the location of the inverter installation and drive the distance between the motor more than 50 meters, the frequency changer selection should cooperate with the reactor to reduce the carrier frequency. 3, a drag: a drive drag more than one motor, if the middle of the cable is too long, universal inverter selection will enlarge the use of a file, and each machine should be installed behind the fuse.
