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:Ordinary 4-pole motor Under the control of the inverter, the higher the speed, the higher the power or the slower the power
- The original you are the ordinary motor ah, this ordinary motor can not afford too high frequency. Often at high frequencies or low frequency work will burn the motor. The higher the speed, the current will increase, the lower the speed, the current will be reduced. Its power is not much change. You still with a special frequency control motor it. Frequency conversion motor is a special design, the use of frequency converter for the drive power, the motor and inverter electromechanical integrated frequency control system, so as to achieve low frequency constant torque operation and high frequency constant torque operation. This motor has good speed performance and significant energy saving effect
- Q:5.5 kW 4-pole motor with the fastest speed can exceed the rated speed?
- Can not be exceeded Although the inverter can run out of the motor rated speed as the motor will soon burn You want your running speed of 2m / s you have to run 5m / s so go eggs do not pull the
- Q:My motor is a low frequency 8 pole motor, about 80W. I would like to choose a frequency converter
- Poor match, the program is unreasonable Current 1.5A, choose a single-phase 220v power supply, 370-500w inverter it
- Q:The inverter is running independently
- . Main working circuit (1) Operation circuit: the external speed, torque and other instructions with the detection circuit current and voltage signal comparison operation, determine the inverter output voltage, frequency. (2) voltage and current detection circuit: isolation with the main circuit potential detection voltage, current and so on. (3) drive circuit: drive the main circuit device circuit. It is isolated from the control circuit to turn on and off the main circuit device. (4) speed detection circuit: mounted on the asynchronous motor shaft speed detector (tg, plg, etc.) signal for the speed signal into the operation loop, according to the command and operation can make the motor running at the command speed. (5) protection circuit: the detection of the main circuit voltage, current, etc., when the overload or over-voltage and other abnormalities, in order to prevent the inverter and asynchronous motor damage
- Q:Master Hello a machine requires 500 speed matching 6-pole motor frequency converter transferred to about 28HZ
- 6-pole motor synchronous speed of 1000 r / min, the actual motor speed is lower than the number, the actual speed is required to 500 r / min, then the motor and passive pulley diameter ratio of about 1: 1.6 or so, and then specific With the inverter to speed up to achieve the purpose, please refer to.
- Q:What is the laptop power adapter? Is it the battery?
- Power adapter is inserted in the plug-in power cord connected to the black, rectangular cube that thing, after the power adapter into a notebook acceptable voltage,
- Q:B2b frequency how to speed
- AC motor speed control methods are four: frequency, transformer, variable pole and winding motor to change the rotor loop resistance of the speed control method. Its source is based on the motor speed formula: n = (1-s) * 60f / p where: n --- motor speed s --- motor slip f --- power frequency p --- motor pole Logarithm
- Q:Yaskawa inverter reported base blockade what is the reason?
- For example, when you stop the inverter, there will be a signal to the inverter, and then the inverter will base block, cut off the output, the motor will no longer work; when you need the inverter work, There is a signal to the inverter, the inverter to cancel the base blockade, it is normal work,
- Q:East yuan 7200GS inverter start 11KW 4-pole motor and 2-pole motor need to modify what parameters?
- motor to be slightly larger, the speed of 4 pole speed is 1450 r / min, 2 pole is 970 r / min The With the inverter control, you only need to modify the parameters of which the motor parameters, and then the motor parameters from the study on it, the most important is your use of inverter equipment and control methods, and then the above two factors Feature adjustment parameters. There is to pay attention to the use of the inverter environment, the inverter is an electronic product, the environment is relatively high, in the use of as much as possible to improve the use of the environment.
- Q:Who knows how the frequency converter works
- 3. Control circuit Now the basic converter with 16-bit, 32-bit microcontroller or DSP as the control core, in order to achieve full digital control. The frequency converter is the output voltage and frequency adjustable speed control device. The circuit that provides the control signal is called the main control circuit. The control circuit is composed of the following circuits: "operation circuit" of frequency and voltage, "voltage and current detection circuit" of main circuit, and "speed detection circuit" of motor. The control signal of the operation circuit is sent to the "drive circuit" and the "protection circuit" of the inverter and the motor Inverter to take the control mode, that is, speed control, turn control, PID or other means
