富士G9变频器（Fuji G9 converter） My inverter history (Fuji) Fuji G9 inverter 3.7 kw-7.5 KW has a common problem: its cooling fan power is large, the speed is high, when the working environment of the dust much will be short! When the fan is broken inverter will not immediately jump overheating protection (may be high temperature Settings), then the whole converter internal temperature is very high, make the drive circuit and power circuit of small capacitance is easy ageing, usually is the first switch power supply to stop working! Inverter does not display!! At this time, the fan and the two small capacitors of the power circuit can be replaced to enable the converter to return to normal! It is best to also change the capacitance of the drive circuit!! Because the frequency converter is relatively expensive equipment, the price difference of different brands is big, the failure rate is high again, so some people are buying the frequency of the frequency of the frequency to worry! We believe that the normal operation of the frequency converter has a great impact on your production; When your equipment is sold far away; When you dont want to give the mechanic a lot of trouble! You still use the famous brand changer with good performance and high price! But not all brands are for you! Some famous brand frequency converter is very delicate (afraid of wet, afraid of dust), must have good environment to have good quality! If your motor running smoothly, not stopped, the load is light, stable power supply voltage, frequency converter work environment is good, have fault also does not affect production, two years bad replacement, maintenance services and close, in order to save money, you might consider buying a lower prices, decent famous inverter! Some people fail to take into account the feel of the frequency converter when debugging the frequency converter. Only according to production needs under the deceleration time to 1 second, inverter often bad, when the speed is too f
