Hello, thank you for your response. The machine is runing good for years (but need every day to let it 30minutes before put the power on the drives, or the indeef module will not come on) and an alarm comes when the mahine was cutting: infeed module error. When i have restart the machine, when pushing the power button the led green goes off BUT the yellow led don't come on, and after 3 seconds an alarm of infeed module not ready come. I have check the DC BUS that goes to 550V and drop. I have check it alone and the same problem the yellow led don't come on, or for some second only. So, i have unmount the module and opened it, checking the power section (with the help of pdf's in the forum) with multimeter diode mode and the power section seem's good. After that i have check all the fuse in the control card and the fuses are ok. I have check the main contactor auxiliary contact, and THERE is a bad contact's (100ohm on NC), so i have exchange it. I have checked the all the internal relay by dismanting from the card and seem's ok. After that, i have mount the module in the machine and now the alarm of infeed module not ready comes on startup before pushing the power button, but the yellow led goes on now when pushing the power button. The machine is a lathe CNC with 3 axis: X Z and C rotary axis + spindle. The module is a 6SN1146-1BB02-0CA1 (is the same as 1145 but heating is external). The DIP switch is all on OFF. We never change it. I have check the ribbon cable with continuity tester and seem's ok. I have check in the service display that the DC BUS is measured correctly, have 575~585V on each drive, and have the drive ready = 1 for each drive. I have check the emergency circuit and seems ok.

I send PM to you again please check. you can continue try to fix the module by yourself. here I attached X151 connecter pin out , maybe help you a little . IGBT is not big problem, but if the Siemens hybrid --there are some small brown colour circuits, soldiered vertical on the mother board , if they are defective , the module possible not worth to repairer. there is also some seller selling that parts on line but not in eBay. contact me by email good luck
