西門子6SE7021伺服器報F025/F008維修，西門子伺服控制器/伺服驅動器6SE7021售后維修廠家，故障維修分析法：對于6SE70系列變頻器，由于質量較好，故障率明顯降低，經常會碰到的故障現象有（直流電壓低），由于是直接通過電阻降壓來取得采樣信號，所以故障F008的出現主要是由于采樣電阻的損壞而導致的。此外，還會碰到F025、F026、F027關于輸入相缺失的報警，故障原因一是由于6SE70系列本身帶有輸入相檢測功能，輸入檢測電路的損壞會導致輸入缺相報警，如排除此故障原因，報警信號還不能消除，那故障很有可能就是CU板的損壞了。此外F011（過電流）故障也是一個常見的故障，電流傳感器的損壞是引起此故障的原因之一，此外，在維修中經常會碰到驅動電路和開關電源上的一些貼片的濾波電容的損壞也會引起F011報警，要特別注意由于這種原因而引起的故障報警。
