I had 2 do that just this last week
One was it was too hot where it was installed. And one was the guy I let wire up the motor didn't tape the butt splices up good.
I just did and new carwash 32 VFD the room where there at hit about 110 f
The one that shuts down has no cabinet fan.
The room did have air condition they figured it save money not to have it new air going in this week.
Your case tho with no motor it should not show error or most don't
read the manual and reset the VFD
Can you help me with this.
I've read the manual, off this equipment, but I'm having some difficulties on resetting this error, can you please advise.
this software is not the most intuitive.
As I mentioned, If the output is disconnected, there should not be an OL error, if it does it at switch on without any thing on UVW, then it points to a short in the VFD output, if so you cannot reset it until the defect/fault is resolved.
Max.
