hello siemens big family, another new problem on my power modul which showed me a temperature fault the last time i posted the problem here. after having put a ventilator, my problem was solved. here is that yesterday a new fault F30021 which appears as soon as the operator starts the machine and I had worked until 1am but, I could not find the solution. I checked the ground connections of the power modul and that of the motor by disconnecting the earth wire, I checked the power cable between the motor and the power modul. I checked the motor windings and after all these checks, I noticed that there was no problem at these different levels. at the moment i'm a little stuck but i suspect the power modul which i think is defective. because when I read the help of the fault F30021 which says: the defective current transformer, additional cause in the cases cu310 / cua31. but, I'm not 100 percent sure. I really need your help to be able to find a solution to my problem. thanks and best regards. ------------------------------------------------------------------------------------------ |
