First, Its nice to read all of above posts.. I feel like we all are sitting at one round table and talking about pasts and all... Now, why only for PLC??? I would like to write about my first drive commissioning Well, I studied so many times and checked panels at our office but never commissioned and my first commissioning was for crane in one of the steel plant very far from my place It was a bit exciting for me because I was commissioning alone and for the first time I went that far - but guess what For in my first commissioning, when we gave 3 phase supply to drive, pre charging resistor blew up... I was shocked... to add my shock, customer replaced drive and when we started that, again smoke came out... oh.. what a feel.. then we replaced DBU too and again start same drive and thank god .. this time it was working (don't know problem was forming or DBU) Then, I commissioned so many drives, and then I went abroad first time - here I faced some hardware fault and first time I opened drive, more over I faced some problem in parameter settings too - at this time I first joined this forum to get help and at that time, campaign was running (I didn't knew that time) and for each question, I was getting very quick reply. This thing attracted me to come here often, and today I must say whatever I know about drives, 50% contribution is from this forum I would like to thank AMAZINGAHMEDfor starting such a wonderful thread which refreshed nice memory Regards, Devesh Vithani |

Thank you for sharing those nice (not so nice for you at the past) memories. But looking at your consecutive drive blows, do you think that you should have fed the 3 phase to the drive from the output side (with incandescent lamps in the way) for the capacitors to charge at first?beacuse drives tend to loose charge due to storage.
