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: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 your description of the problem, the patrol instrument shows that there has been a disturbance, then it shows that the patrol meter itself has been greatly disturbed and the work is out of order! If you can't add these two options, you can only change the test scenario.

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: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:Schneider 303 4KW frequency converter F 013 trouble shooting method: You see when the alarm is started, or stable operation alarm amount, different times, different analysis

Q:What are the parameters of the frequency converter? Thank you: Also called torque compensation, in order to compensate for the motor stator winding resistance caused by low-speed torque reduction, and the low frequency range f/V increased method. When the utility model is set as an automatic, the voltage in the acceleration can be automatically raised to compensate the starting torque, and the motor can be accelerated smoothly. If manual compensation is adopted, according to the load characteristics, especially the starting characteristics of the load, the better curve can be selected through the test. For variable torque load, such as improper selection, the output voltage is too high at low speed, while the phenomenon of waste of electricity, and even the emergence of motor load with a large current, while the speed does not go.

Q:If you don't plug in the PG card, do you use PLC's PID control?Plug in the PG card and the PLC PID control, which is reliable and precise?: There are several kinds of closed loop, speed closed loop, temperature / pressure / flow closed loop.Since you're talking about PG cards, then obviously you have to control speed.Generally speaking, the control precision is related to the hardware, and the PLC can also output pulses.If you are small system, simple control, it is recommended that you use PG card + encoder to save the cost, you can inverter internal PID, and control accuracy is also ok.My feeling, as if the speed control precision is high, is PG card.

Q:Application of ABB frequency converter: When the motor is powered by an industrial frequency power supply, the current increases when the voltage drops; for the inverter, if the voltage drops when the frequency drops, then does the current increase?When the frequency drops (low speed), if the output is the same power, the current increases, but the current remains almost constant under a certain torque.

Q:The difference between soft starter and converter: The soft starter is during the start-up of the equipment to take blood pressure or other ways to reduce the starting current of the inverter machine, the device is in operation according to the equipment load by changing the size of the power frequency and regulating equipment output.
