I posted in another thread while searching but there was no solution. In case it's not the same issue, I decided to create this thread.
We have 6 powerflex 40 in a panel (more elsewhere in the plant), when we shut-down power either for maintenance or when they are cleaning (lock out tag out) and we restart. Once in a while, a drive will not communicate anymore and if we wait 10-30 minutes, it will come back alive. That's been going on for nearly 3 years when the equipment was install. (before I got here).
Now I am starting to have the same issue but worst with another drive in the same system.
There was no communication, even if we waited 30 minutes. Last week-end during shutdown, same issue and it took 1hour something before comeback alive. We got the equipment running by installing a contactor but 60hz isn't what we are looking for on this, we need a drive.
It eventually came back but after something like 3 hours.
I don't think my guys tested it on "manual" even if I asked.
Was wondering if anyone ever found the problem and fixed it ?
We don't have all the tools and the knowledge to work on drive and plc, mostly cause we don't have enough issue to keep us busy on this.
When we connect to the drive on a computer, we can see the communication but it will sometimes blink.
On the ones that's been going on for years, we replaced the communication pannels, we replaced the drive and still same issue. I suppose it's ethernet or IT, but how does I find the issue ?
Thank you
