(Noob here)
I have a machine with a series of PowerFlex 40s.
When the machine is idled and no motors are moving, or being told to move, the frequency displays should be reading 0.
One VFD, that drives a motor for a system that we are having a problem is flickering between 0 and some number I can't really read .3 or 3.
I was wondering if this indicates a problem with the drive? Should the display be rock solid 0 or 0.0 when not being commanded, or is this normal? There are about 5 other drives, all which are rock solid at 0 or 0.0 (not at work so can't see)
We are having a little problem with the "system" that VFD drives and aren't sure if the VFD is causing a problem, or if it something else.
(Searched this forum and Google for flickering PowerFlex display and got no results, so I tried to do some homework before asking here.)
Thanks for any help.
