1. It is necessary to consider the touch and current size of the incoming terminal, if the terminal standard is small, perhaps the conductive function of the terminal is poor, which will directly cause the current carrying capacity of the terminal to be small and heated.
2. The incoming wire at the end of the line must be pressed well and the like, if it is not pressed, it may cause poor touch, and the local touch resistance is too large to cause heating, especially the high-power inverter, the current is very large, and the reasonable selection of materials and wire lugs must be selected in accordance with the electrical specifications, and the hydraulic tongs should be used to suppress the device.
3. Maybe there are problems such as wetting in the use environment, and the insulation at the inlet end is too thin or the quality is not good, which may cause arc breakdown and alternative ablation. Maybe move the inverter to a boring place to use, or install dehumidification equipment to solve the problem.
4. Perhaps the load is greatly shaken, so that the incoming current may fluctuate to a certain extent, and the instantaneous current is too large. You can properly optimize the parameters such as the voltage frequency ratio, and at the same time adjust the acceleration and deceleration time to a longer point, and set the carrier frequency lower to deal with it.
5. The bus has a large capacitance, and the aging of the capacitor will directly cause the current of the inverter to waver. When the inverter is just energized, because the bus capacitor voltage is relatively low, the voltage can not change suddenly, and there will be a large current, which is generally solved by the current limiting resistor.

Reynolds inverter frequency
That is, the upper and lower amplitudes of the output frequency of the inverter. Frequency is a maintenance function to avoid misoperation or failure of the external frequency setting signal source, which causes the output frequency to be too high or too low, so as to prevent damage to the equipment. You can set it according to the actual situation in the app. This function can also be used as a speed limit, so that ...
