The touch screen has no display, the screen does not light up, black screen, blue screen, blurry screen, etc. The drive circuit of the inverter is faulty, and the controller is allowed to be put in instead. The working characteristic of the three-pin inverter repair is that when a small forward voltage (is, is) is added between the gate and the cathode, it is turned on. There is current flowing in the load R. After it is turned on, it remains on even if the gate voltage is removed. It is turned off only when the voltage of the anode circuit is or negative. Therefore, only one pulse signal is needed to control its conduction, so it is often used for controlled rectification. , Significant power saving effect: The continuous rise of energy prices and the stricter requirements for energy saving in various national energy bills have made energy saving an important issue that all industries must face. The energy saving of frequency converters is mainly reflected in the application of fans and water pumps. , varistor circuit diagram,) This situation does not exist during the steel rolling process. This situation only occurs after the steel leaves the roller table. In the power circuit, the rectifier circuit turns AC into pulsating DC, and in the rectifier A larger-capacity electrolytic capacitor is then connected to the circuit, and its charge and discharge characteristics are used to turn the rectified pulsating DC voltage into a relatively stable DC voltage. In practice, in order to prevent the supply voltage of each part of the circuit from changing due to load changes, electrolytic capacitors of tens to hundreds of microfarads are generally connected to the output end of the power supply and the power input end of the load. Since large-capacity electrolytic capacitors generally have a certain inductance and cannot effectively filter out high-frequency and pulse interference signals, a capacitor with a capacity of .. is connected in parallel at both ends to filter out high-frequency and pulse interference signals. ,Error in the initialization process when stopping the axis.
