Hello JEYAPRAKASH SP,

The main point is, how you ensured that the drive/control card is having valid data? Unless & until it is confirmed, there is no point to proceed ahead.

Please provide enable signals & reference voltage externally, power ON drive & check if it works or gives error. If it works, you need to check CNC side. If not you need to restore drive data correctly.

One more point - where did you see F-07 fault?

Finally you response. Believe me or not--I have been working with SIMODRIVE 611A the 1st day when Siemens release it (or earlier) . In 1990 , i had worked in the Siemens factory for this drive system near Nuremberg , Germany as final inspector.

Now I need your machine / system story --is it used machine you just got it. and you are making set up to bring it into normal state? Or it was a running machine and something happened--made your 611A like what you said.

 also I want to see the picture of you E/R module status when you think it is ready --please post E/R module picture close look with 6 led's and better terminal block 

PS: safety remove the DC 600V cover most important the position from E/R module to the 1st drive (LT) module--I don't want you make low level mistake --DC bar not connected to drive.

Response--I am sure will help you    

I think I attached manual for , but here is troubleshooting page

 You response too slow, also I am busy . but you don't post any picture of whole drive system special I need to see power supply module when machine "you said is ready to run"

You told story is very important. do you know when using 840C , all 611A drive working good or? 

I suggest you many tips, If you don't post picture and don't try my tips I will stop to post for you

This machine is old one and we just changed control system from 840C to 840Di sl.. I will post again with pictures of all modules. 

Can you explain how to determine ground fault in 611A. From day one I had doubt on ground leakage, which is given for error code 7. i2t=0 & Ground fault. 

 Did you remember I told you try the drive and motor one by one?

anyway you found problem

Problem is solved. We changed IGBT in one of the LT Module. 

But even after energizing busbar, LT module doesn't trips. Also One module is stopping all the other drives function. It was clueless error which we were able to solve by mounting all the drives separately in other control panel. (In other factory) 

Problem was in one of the gate in IGBT which was root cause. Attached. 

Thanks to everyone for giving your ideas.
