Hi I am new to the forum. I am not sure of the model of my drive. It is installed in an Atlas Copco Compressor GA45VSD 60 HP. I have one #6SY7000-0AD76. Also the cooling fan is KE220AB06-09. I am hoping these numbers mean something. I have a F025 fault. It tries to start the motor then fails. I found a shorted IBGT in U phase and replaced it thinking that was the fault. But when put back together I still had F025. I tried rotating the motor phases with no change in the error. But noticed the inrush current on start was very low on U phase. Tried changing the CT's no go. On pulling it apart again I found a lower diode check reading on the A100 circuit of what I believe is the IVI board. (The board that fires the IBGT's) I found a shorted Diode S413 but am having troubles sourcing 1. I ordered what I thought was the correct one from Mouser and got a 1MM square one instead of a 2mmX4mm surface mount device. Would anyone have an idea where I would find the proper diode? Thanks ------------------------------------------------------------------------------------------ |
