Why can't I walk up to brand x VFD, punch a few keys on the keypad and perform a megohmeter test? Doesn't the VFD contain the necessary hardware to pull this off with modest accuracy?
I know of some old Telemechanique drives we had that do a test when you enable them whether you want them to or not. There was no parameter to disable/enable this feature which lead to faults at times.
By why can't I get a meghohms test at up to 600V and a readout plus or minus a few k?
