Q: What is the difference between a frequency converter and a servo controller?: The inverter is actually an inverter. It is the first AC into DC. And then use the electronic element to switch DC power into AC inverter. In general. Large power SCR. And an adjustable frequency. The device can be adjusted in a certain range of frequency is used to control the motor speed. The speed can be adjusted. In a certain range. The inverter is widely used in AC motor speed.Frequency conversion motor and AC motor is not very different, but the high-frequency loss of materials used is small. Ordinary AC motors can also be frequency conversion speed regulation

Q: Surface grinder can add frequency converter, what are the advantages and disadvantages?: System overviewA. load - constant power propertyWhen the gearbox changes, the torque varies inversely with the speed. Excluding the loss of the gearbox, it has the characteristic of constant power in the full power range.1) the speed grade speed control box has 8 gears speed: 75, 120, 200, 300, 800, 1200, 15002000r/min.2) the main rated parameters of motor, rated capacity: 3.7KW, rated speed: 1440r/min, load characteristics: constant power3) the control mode is controlled by 8 positions of the 8 handles, so that the four clutches can be divided and joined, and the 8 combinations of gears can be obtained, so as to obtain the speed of the two gears.The overload capacity of B. at low speed is strong, and the rated torque will be much larger than the maximum working torque of the load when the drive system is lowered at low speed, and it has a strong overload capacity

Q: What does a frequency converter do?: Mainly used to drive AC motors, AC motors to achieve stepless speed regulation.For example, for the fan, with frequency converter to adjust the speed of the motor speed, you can change the size of the air supply.There are many occasions that need speed regulation. Using frequency converter to speed up is simple and energy-saving.

Q: When the inverter is running at full 50HZ, the output voltage decreases and the output current becomes smaller. What is the reason?: If the load of the motor is increased, the slip S is increased, the electromotive force of the motor is decreased, and the electric current of the motor will become larger. That is to say, when the motor is running in the overclocking stage, the load of the motor is light, the current will become smaller, and the current will not be smaller if the load is negative. Didn't I make myself clear?

Q: What is the main function of the frequency converter on the machine tools?: Where is the difference between soft starter and converter?

Q: How does the PLC process the inverter output signal?: Depends on analog or switch volume, if it is analog, you can use analog input module, if it is the amount of switching, with ordinary IO on it

Q: How can I control the frequency converter with a computer?: The commonly used PLC and DCS control system in industrial area are applicable to the conditions of inverter interface control module, can realize the closed-loop converter convenient automatic control in the control system, widely used in large and medium. The control device for some smallexperimental device and embedded processor in inverter control, generally also need to deal with the keyboard input, display, data acquisition and other work such as process control, this control is more suitable for single-chip control system as the core, and uses PLC and operation panel, it can achieve the function but the cost is too high. Should not be used.

Q: Is the voltage low? The younger brother is bored to death, no problem with the wire drawing machine, the full load will jump off. Display frequency converter overload and acceleration operation overcurrent. Help me please.: The difference between the display value and the measured value shows that the bus detection circuit is abnormal if the deviation is larger. Conversely, if the two value deviation is minimal or equal, the missing phase signal is abnormal. At present, there are two kinds of bus detection circuit used in our company: resistance voltage divider and operation comparison amplification (TL082). Corresponding to the detection circuit output 0 - 3.3V corresponds to the actual bus 0 - 1000V, the two circuits are relatively simple, maintenance only need to test the key point voltage in the circuit, you can easily find the fault point.

Q: What are the contents of frequency converter maintenance?: Operators must be familiar with the basic principles of inverter, functional features, with basic knowledge of electrical operations. Before checking and maintaining the frequency converter, the total power supply of the equipment must be cut off, and the inverter Chang lamp will be completely extinguished.

Q: Which brand of converter is better?: Shanghai Leinuoer recommended! Soft starter and frequency converter products Shanghai Leinuoer company, national key products, Shanghai famous trademark! People's Insurance Company of China quality assurance! Shanghai World Expo Shanghai reyrolle company supporting the project, the Beijing Olympic Games project,
