Q:How do you set the frequency with panels?. What are the specific steps?: Concrete steps are:1, the parameter 700 is the starting signal, the 1 is the panel button starting, and the 2 is the external signal starting;2, the parameter 1000 is the frequency setting value, and the 1 is the panel lifting mark key to change the frequency, and 2 is the external analog signal change.3, the starting signal is set automatically, then the parameter 1000 is 1, the panel is set frequency, and the parameter 1031 is set to 1 so that the frequency value after the change is saved automatically.

Q:PT100 temperature patrol instrument, when the converter is not open, the measurement is normal. Once opened, it shows completely disorder, and sometimes there are puzzling characters. How can I solve this problem? Please enlighten master!: In the complex electromagnetic environment, AnyWay advocates the idea of digital front end, that is, in the vicinity of being measured, the signal will be digitized, and then the uploaded information will be uploaded to the host computer through digital communication. Digital transmission is much better than analog transmission in anti-interference ability. If the electromagnetic interference is very large, the transmission line can be changed into optical fiber transmission. In this way, the transmission link can completely avoid interference.

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:Check the fault information is the power supply voltage instability, but other inverters are running well, what is the matter? Will there be any other parameters are not set correctly, thank you!: This example is obvious, due to undervoltage, to find the problem of power, the first to exclude external problems, from the inverter inside to find the reasons.

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 inverters with the same frequency and start signal, so that it can be synchronized; another way is to do in front of a given frequency inverter with potentiometer, given analog output signal of the first station to do second machines, it can be done simultaneously; but you have to say clearly what is what specific brand series in order to further clear the inverter parameters, otherwise only vague answers.

Q:I do mining equipment, recently I used ABB frequency converter to put into our equipment, but the problem of interference really gives me a headache! We have two pieces of equipment of SIEMENS S7-200 PLC, and is used in point to point protocol communication with each other, when the converter work PLC communication interference! There are monitoring equipment, converter work, there are a large number of snowflakes on the screen, simply do not see! Not even an internal phone! I've done well in grounding, but I still can't do it! Is there any master who can teach me a trick?: Solution of interference caused by inductive coupling:The control circuit using shielding line, when connected to the control line and the inverter, the shielding layer can not only be grounded, one end connected to the transducer signal terminal can pay attention to public, regardless of whether the public or end shield grounding, only in the end, and can not be connected at both ends.

Q:Application of ABB frequency converter: What is the difference between a voltage type and an electric current type?The main circuit of the inverter can be divided into two categories: voltage is DC voltage source converter for AC inverter, the DC circuit is the filter capacitor current is DC converter; current source for AC inverter, the DC circuit filter inductance stone.

Q:Why does the frequency change when the frequency converter regulates the frequency?: Main flux of motorM = U/ (4.44*f*N)In the upper model, the U is the stator voltage, that is, the output voltage of the inverter, f is the frequency, and N is the stator winding turn number.N is a constant.Obviously, when the frequency changes, if the voltage is constant, then the flux will change.The iron core of the motor is nonlinear, and when the flux changes, both too large (saturated) or too small (weak magnetic) is detrimental to the motor.Therefore, when changing the frequency, the voltage is changed, and the constant value of U/f is kept, so that the magnetic flux can be kept unchanged.

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:What is the difference between inverter energy consumption braking and motor energy consumption braking?: A direct current is generated in the stator winding so that a fixed magnetic field is generated. At this point, the rotor cuts the magnetic field lines in the direction of rotation, resulting in a braking torque. Because the braking method is not like regenerative braking (using frequency converter), the energy generated by braking is fed back to the grid, but the energy is dissipated by the motor alone, so it is called energy consumption braking. The utility model is also used for braking by direct current in the stator winding, so the energy consumption braking is called DC injection braking. By using the backward switch Q to return the point voltage back to the grid, the armature current will become a copy, and the current will be of the same magnitude, resulting in a great braking torque of the motor, which will stop the motor.
