I'm trying to configure Altivar 312 VFDs, but my safety circuit drops 3-phase input and currently that also causes the logic/communications to go down as well. All the documentation I've looked at seems to indicate the 24VDC on the drive is and output to provided a convenient source for the logic inputs. I'm wondering if I can back drive this to power the logic side of the drive without hurting it.
I'm just sitting on my hands right now since all the guard doors are open and I need to be troubleshooting a communications issue.
