Spindle Axis Fault
		Hyundai Hit-30 lathe w/Siemans drive. Machine Alarmed out during production.Blew 1 of the 150amp fuse of the 3 legs into the machine.New fuse installed.Upon powering up,all working untill trying to turn spindle.Inspected Spindle drive power 6SN1123-1AA00-0EA1 which had a blown IGBT. We replaced the Drive but are still getting a spindle drive fault when I try to rotate the spindle. It will also alarm if I turn the spindle by hand.The spindle drive motor tested good. Could I have damaged the software board? (6SN1118 ODG23 0AA0)

Maybe try swapping out the I/R module?

Check the motor winding resistance after disconnecting the power cable. Check whether the DC link voltage is present. Regards Syam

I have checked everything out and now I suspect the replacement drive I put in is faulty (6SN1123-1AA00-0EA1). It is a used unit that was purchased from a reputable company that had tested the unit before I recieved it. I bench tested it according toSiemans recomended procedure and it test out fine,But it fails when power is applied.I found this out by swapping it out for a known good part in a another running machine. (Same failure,same fault codes.) Ishould recieve another replacement drive today and will try again.I'll post the results. Thanks.

The replacement Spindle drive would fault out when power was applied to it, even though it would bench test OK. I had another shipped overnight and now all is good. Although the lathe was down for a week,at least I learned much about Siemans Drives! Thanks all and take care.
