Ultrasonic tuck cotton converter repair Yung economic electromechanical engineers meticulously maintained, always makes the user feel satisfied, because the whether machine internal power supply circuit, or parameter optimization settings, as well as the external cleanliness, do a new look. Ultrasonic tuck cotton inverter repair failure analysis, E9 error: check the three-phase input side of the power supply, J300 inverter with three-phase input voltage detection input voltage dividing resistor to the CPU processing, phase loss and The input voltage is too low in the case of error may have thrown E9. 2, E30 - IGBT error: the E30 alarm the possibility there are several aspects: the main damage to the power module, the SJ300 series inverter small and medium power produced by Japan's Fuji PIM modules, rectifier and inverter for integration module with IPM intelligent modules used in Japan and differences between them, of course, the the damage module will result in the generation of E30 fault. Ultrasonic tuck cotton inverter repair application performance, electrical energy and stepless speed dual utility. Automatically adjust the motor speed according to the load characteristics, the load to keep saving conditions, has a soft-start feature, does not start when the impact of current and mechanical vibration; throughout the optimization design: can effectively reduce the noise of the motor is running and fever, reduce motor maintenance extend motor life 2 to 4 times, lower maintenance cost; 3, has mains power saving state dual circuit automatically converted without interrupting the power supply circuit, automatic fault alarm does not affect the normal work; wide voltage design speed tracking feature to protect the economizer can still work in the case of frequent fluctuations in the grid voltage. Harmonic management: product design safe handling the EU WEEE scale design, in line with EU disable hazardous substances RoHS certification requirements. Built-in chokes, sine filters restrain harmonic, reduce pollution on the grid.
