One would think that there should be some attempt at standardising Error codes accross all VSD manufacturers . Any one have a thought on this?

That would be quite a task, given what a range of features there are out there from simple drives that just follow a speed reference to ones that have hundreds of features and consequently hundreds of things that can go wrong.

This is why i encourage asset owners to find a product that works for them, and stick with it. If you have a plant full of Brand X drives, then very soon everyone learns what fault messages actually mean and what to do about them.

If every fly by night salesman gets given the opportunity to chuck their product in, soon you have such a mish mash of gear that no one is a specialist, it's too expensive to carry direct replacements, and managing drive parameters and configuration is a nightmare.

Since there's no real benefit to manufacturers to standardize I don't see it happening, personally.
 
+1 For Brand X
I did a program conversion for 3 identical machines from relay logic to PLC and had to do the installs one at a time over weekend each was in a different state. The drives were to be updated to 60 hp VFD purchased and delivered by each plant and I had requested ABB
Drive since I was familiar with programming it. Instead each plant purchased different drives that they thought they got a "deal" on and I wasted a day at each plant reading a 500 page manual.
 
Somehow the manufacturers (at least the major ones?) keep to the same standard for protective relays. But I guess they are much simplier, it's always the same type of faults you can have basically.

Otherwise I agree with Saffa and roxusa. The standard should be at the plant/factory to use same brand/model line-up. Or two if you want to get some competition between manufacturers. Should be the same for PLC/DCS as well... And all other more advanced equipment.
 
The only way to do that would be to find the lowest common demonenator in every fault, resulting in bland generic messages that would not tell you anything useful on your specific drive.

And also, this

I could see possibly standardizing on fault ranges 100-199 is temp faults, 200-299 is incoming power faults, etc. That way glancing at the number would at least give you a hint at what is going on.

However, since a lot of the device manufacturers also have existing legacy fault numbering, you would need an additional setting to choose to display their new "standardized" numbers compared to the older preexisting fault numbers.

Manufacturers will sell what people buy. If users push hard enough, it could happen. But I don't see it happening, and there are enough purchasing people who buy based on cost and nothing else that plenty of manufacturers could ignore the standard and do just fine.
 
So if you have a VFD that displays fault information in text using a language of your choice, you must abandon that in favor of a set of numbers? No matter how universal you make the numbers, that is a step backward in my book...
