變頻器被送來時,有若干不同的報警記錄。在通電測試過程中同樣出現(xiàn)各種虛**報警。認(rèn)真清洗控制板與驅(qū)動板連接扁平電纜插座焊點后,問題解決。
硬件故障
這類故障主要指系統(tǒng)中的模板(特別是I/O模板)損壞而造成的故障。這類故障一般比較明顯,影響局部。

After preliminary inspection, the rectification part and inverter part of Siemens CNC axis card were in good condition, so it was powered on for inspection. The DC bus voltage is normal, but the starting voltage of the switching power supply control chip 3844 is only 2V. The resistance value of partial voltage resistance is much smaller in online detection, and it is normal in offline detection. The problem was solved after the Siemens CNC axis card was repaired by washing method. It turned out that the positive pin pad of a capacitor was very close to the 0V layer, and the residual flux made it in a semi conducting state.
When the frequency converter is sent, there are several different alarm records. Various false * * alarms also appear during the power on test. The problem was solved after carefully cleaning the welding point of the flat cable socket connecting the control board and the drive board.
Hardware failure
This kind of failure mainly refers to the failure caused by the damage of the template (especially the i/o template) in the system. This kind of fault is generally obvious and affects local parts.
