Q:It was when processing a workpiece, processing spindle stops suddenly (other are normal) a check is, I jump out of the inverter, I can click on a processing, and then processing not long after they happen, (do not open the machine spindle machining will also be the case)
Suggest you in the inverter power installed a frequency converter input filter, try it, feel a bit like electromagnetic interference caused by frequency converter mistakenly stop ah.
Q:What is frequency conversion? What is the function of frequency converter?
Power factor compensation, energy savingThe reactive power will not only increase the heating power loss and equipment, more important is to reduce the power factor of the power grid leads to the decrease of active power, reactive power consumption in a large number of lines, low efficiency, serious waste of equipment, the use of frequency control devices, the inverter internal filter capacitor, thereby reducing the reactive power loss, increase active power grid.
Q:What is the working principle of elevator frequency converter?
Yaskawa 616G5 transducer current vector in the world as one of the inverter control, speed range to reach 1:1000, the control accuracy of 0.02%, with the starting torque at zero speed can reach 150% characteristics. In particular, Yaskawa unique all fields, automatic torque boost function can get comfort and good stability in the lift drag in.G5 can accept controllers such as multi speed frequency command PLC or analog voltage and current instruction; can adapt to all kinds of motor vector control and self-learning to obtain good characteristics; low speed starting smoothly excellent reliability and high cost of hardware.
Q:There is much dust and moisture in my workshop. Many brands are not durable.
You can't do anything like this! Dust will fall on the circuit board and cause short circuit of the component. The same humidity.Suggest to strengthen the protection level of cabinet. But heat must be taken into account. Or make an independent electrical room. Install air-conditioning. As God offered!
Q:What does the RUN key on the inverter mean? How do you use it?
When selecting panel operations (when the panel of the inverter is the control source of the inverter), it is the meaning of the "running" button.Frequency converter (Variable-frequency, Drive, VFD) is the application of frequency conversion technology and microelectronics technology, by changing the power supply frequency of the motor to control AC motor power control equipment. The frequency converter is mainly composed of rectifier (AC DC converter), filter, inverter (DC AC converter), brake unit, drive unit, detection unit, micro processing unit and so on. The inverter adjusts the voltage and frequency of the output power by disconnecting the internal IGBT
Q:What are the differences between the two quadrant and the four quadrant of the inverter?
Simply put, the two quadrant ordinary inverter can only drag the motor forward or reverse. Work in one and three quadrants. The kinetic energy of the motor idle time can only be wasted. (of an electric motor)
Q:Application of ABB frequency converter
What are the differences between PWM and PAM?PWM is English Pulse Width Modulation (pulse width modulation), according to the law must change the pulse of the pulse width in a tone adjustment output and waveform.PAM is the abbreviation of Pulse Amplitude Modulation (pulse amplitude modulation) in English. It is a modulation way to change the pulse amplitude of pulse column according to a certain rule to regulate the output value and waveform.
Q:What is the difference between frequency converter and servo driver?
The general use of the situation, such as high-speed, high-precision positioning equipment, servo, high power speed control using frequency conversion.Like the central air conditioning system, elevators and so on, many places use frequency conversion; like the textile machine, the placement machine, the plug-in machine uses the servo. In fact, many cases are used in conjunction with the two systems, according to the needs of the design arrangements.
Q:Why does harmonic generator produce harmonic? What's his working principle?
Harmonic generation mechanism of inverter inputThe main circuit of inverter is composed of AC-DC-AC, external input 380V/50Hz power supply through the three-phase bridge rectifier, a DC voltage, AC voltage by the capacitor filter and high power transistor switching element for variable frequency inverter. In the rectifying circuit, the input current waveform is a rectangular wave irregular waveform, according to Fu Liye series is decomposed into fundamental and harmonics, the harmonic frequency is usually 6N + 1 harmonic, the harmonic interference input power supply system. If the reactance of the supply side is sufficiently small and the commutation overlap angle can be neglected, then the n order harmonic is the 1/n of the fundamental current.
Q:What is the main function of the frequency converter on the machine tools?
The following example to three inverter in the application of the note for example!CNC machine tool is a kind of flexible and efficient automatic machine tool. It can solve the complicated, precise and small batch processing problem. It is very important to improve the machining accuracy and efficiency of CNC machine tools by rationally controlling the spindle of NC machine tools.
