This is an important and necessary method to protect the frequency inverter components from damage. This fault cannot be shielded either. There is a bus voltage check mechanism inside the frequency inverter. When the measured value of the bus voltage is lower than a certain threshold, the frequency inverter will report an undervoltage fault. There are many reasons for the undervoltage of the DC bus, which should be analyzed according to the actual situation. If you find the right root cause and then prescribe the right medicine, it can usually be solved. 1. The first is the influence from the incoming line voltage. 2. The second is the influence from the output end, that is, the inverter side. 3. Finally, there is a hardware problem.XCD-E7000 product application industry: Processing centers, large complete sets of equipment, plastic machinery, textiles, printing, copper materials, printing and dyeing, packaging, woodworking machinery and other industries
