NEED HELP-During machining a part,1 leg of the 3 phase into my shop blew out,either due to or caused by a IGBT on the spindle drive that also blew out.After checking the motor and replacing the power section of the drive,I still can't get the spindle to turn.It continually faults.All other drives work fine. Any Thoughts?
Thanks


Simodrive 611 , 840D control

Turns out my replacement drive was bad,even though it would bench test OK,when power was applied it would fail. I had another shipped overnight and this one has me up and running.
The only problems I seem to have with this lathe are the Duplomatic turret with live tooling,and chasing down problems with the Siemans electrics.
Oh well, i'm learning more all the time!
Thanks.
