Q:What is the frequency converter through function?: Some inverter has this function, such as the ACS800 series has lost power across functions, can be in a temporary loss of power grid when using mechanical transducer can keep running, as long as the rotation of the motor and the inverter to provide energy, although the speed will decrease, but the converter will run normally (power mode), and if the grid connected inverter in the state power grid voltage recovery after the inverter can be immediately put into normal electric state.The undervoltage controller needs to be activated (parameter 20.06).

Q:There is a feed and send system. Now due to the severity of the material is not the same as the two converters often change speed, the workers do not understand their own, often by, often bad now how to use the best way you can use a potentiometer or other method, control of the two frequency converter, synchronous operation. Is to adjust one, and the other also with the kind of frequency, so that you can let the workers themselves to open, and the two inverters, the same manufacturer, the same model, the same load,: Two start with frequency conversion. The frequency converter is controlled by a potentiometer, and the analog output signal (AO.GND) is sent into the converter and connected to the AI.GND port of the converter. If the pulse port can also be connected to the pulse port.

Q:Which brand of converter is better?: Supporting the use of Sinopec group, double coin group and other national key projects, the quality of product quality and good customer service service won the praise of users!

Q:How does the frequency converter change the voltage and change the speed of the motor?: The inverter does not change the voltage to adjust the speed of the motor. Under the premise of constant voltage, the frequency of the alternating current is changed to adjust the speed of the motor. Typically, at the frequency of 50Hz, the synchronous speed of the quadrupole motor is 1500 rpm, and if the frequency is increased to 60Hz, the synchronous speed should be 1800 rpm; if it falls to 40Hz, the synchronous speed should be 1200 rpm. In the limited frequency range, the power is constant, the higher the speed, the smaller the torque, the lower the speed, the greater the torque. Formula for speed calculation (Rev / min):60 seconds * / log polar frequency. The middle pole of a pair is 2 poles of 1 pairs, i.e., the quadrupole motor is 2 pairs of magnetic poles.The frequency of the converter is stepless, continuous and adjustable, so the speed of the motor is continuously adjustable in a certain range.

Q:What are the contents of frequency converter maintenance?: Regular maintenanceClean air filter, cooling air duct and interior dust. Check whether the screws, bolts and plug are loose, the input and output reactor ground and interphase resistance is short circuit, the normal should be more than tens of megabytes of europe. The conductor and insulator are corrosion phenomenon, if in time to wipe clean with alcohol. If the conditions permit, use the oscilloscope to measure the stability of the switching power supply output voltage, such as: 5V, 12V, 15V, 24V and other voltage. Is there any distortion in the square wave of the measuring circuit?. Is the UVW phase waveform sinusoidal?. The contact of a contactor whether traces the strike, serious to change with the same or greater than the original capacity of new products; confirm the correctness of the control voltage, the order of protection test; confirm that there is no abnormal loop protection; confirm the balance of the inverter output voltage in a single run time.

Q:I would like to ask vector control of the frequency converter, how the motor does not turn. What parameters are set up: Because the dynamic mathematical model of induction motor is a high order, nonlinear and strong coupling multivariable system. In the 70s of last century, SIEMENS Engineer F.Blaschke first proposed asynchronous motor vector control theory to solve the AC motor torque control problem. The basic principle of vector control is achieved through the measurement and control of induction motor stator current vector, according to the principle of field orientation respectively, excitation current and torque current of induction motor control, so as to achieve the purpose of controlling the torque of asynchronous motor. In particular the stator current vector is decomposed into a component of current magnetic field (excitation current) and the torque producing current component (torque) to control respectively, and at the same time to control the amplitude and phase of the two components, namely the control of stator current vector, so that this control method is called vector control mode. In brief, the vector control is to decouple the magnetic flux and the torque, which is beneficial to design the regulator of both of them, so as to realize the high speed control of the AC motor. There are vector control methods based on slip frequency control, speed sensorless vector control method and vector control method with speed sensor. Thus, a three-phase induction motor can be equivalent to a DC motor to control, so as to obtain the same static and dynamic performance as the DC speed regulating system. Vector control algorithm has been widely used in Siemens, AB, GE, Fuji and other international large company frequency converter.

Q:Delta inverter fault output which parameter is set?: Overload overload fault include frequency overload and overload. The electric machine may be accelerated in short time, the DC brake is too large, the grid voltage is too low, the heavy load causes. Usually by extending the acceleration time and prolong the braking time, check the power voltage. The heavy load, the motor and inverter can not drag this may be due to mechanical load, lubrication is not good. The former must replace high power motor and inverter; if the latter want to overhaul production machinery.

Q:What are the benefits of installing economizer in industrial enterprises?: The input and output filter and the DC reactor in the economizer can prevent the harmonic produced by the converter and cause the pollution of the power grid and the surrounding electricity environment.3 、 no disturbance power supply / electricity saving conversion system is beneficial to ensure that the customer load can be put into use quickly when the machine fails, and the normal production of the customer will not be affected. At the same time, the protection function of the economizer is perfect, and it has the protection function of over voltage, under voltage, over current, over temperature and surge resistance.4, reactive power compensation, improve the power factor of the system, reduce reactive power loss.

Q:The frequency converter works with sharp noises. What's the process of converting electrical energy into mechanical energy?. The mechanism of sound making. Thank you: The input is AC 50Hz sine wave output frequency variable, but still want to be sinusoidal. But due to various reasons such as the efficiency and control it is not directly output sine wave. It is the original inverter with high frequency sine wave modulation is Fang Bo, will be on the radio. As the modulation principle this is also called the square wave carrier. Between hundreds to thousands of HZ. In the range of our hearing. When it can be produced by mechanical vibration equipment such as reactors will sound when conducting ]. This is the voice we heard.The frequency of electromagnetic waves is high, that is, the corresponding mechanical vibration can occur, and it is also the frequency that the human ear can not hear, so it can not be heard

Q:Why does the frequency converter cause interference?: Method for solving interference caused by frequency converter:Adopt software anti-interference measures: specifically, the carrier frequency of the inverter is lowered through the man-machine interface of the inverter, and the value is reduced to an appropriate range. If this approach does not work, then only the following hardware anti-interference measures can be taken.Carry out the correct grounding: through the field investigation, we can see that the site of the ground is not ideal. The correct grounding can not only effectively suppress external interference, but also reduce the interference of the equipment itself to the outside. It is the most effective measure to solve the interference of frequency converter. Specifically, do the following two points:
