Hey guys,
I need urgent assistance regarding an issue that I am facing with power flex 753 drive, Rockwell Automation installed in one machines here.The HIM unit of the drive was not starting up & hence I had suspected the power interface card to be faulty.
Subsequently , I had replaced the card & when I switched on the power the HIM unit had started working,but as soon as I issued a start command to the drive the IGBT burst open !!& the entire unit smoked out.
I am at loss to understand as to what happened??I had checked the connections multiple times after installing the card & didnt find anything wrong
Pls help!
