Howdy folks
Just wondering if there's someone out there who's had this same issue i'm having.
Customer purchased a machine with a SEW Eurodrive VSD(VFD) fitted, the machine was powered up several times this morning with no issues, this afternoon the machine was powered up everything work except VSD, checked incoming power all fine - 3 phase @ 430volts present as it should be yet unit was not powering.
Rang SEW support who told me if not powering then the drive is fried, not sure how it could be when all the other 3 phase components are working fine. So went out and purchased an ABB VSD with matched specs, checked incoming 3 phase volt before powering up the new drive - all good, powered the new drive up and nothing, unit didn't even light up on the front panel, again checked incoming volt and all was correct.
Check both manufacturers manuals but no help on this problem.
Anyone have any ideas to why this is happening?
Any help would be appreciated.
Thanks in advance
