AB 1333 phase loss

There is no phase loss protection or parameter. The drive output has to be run thru a overload block. That overload block can provide the phase loss protection.
There is a diagram of this on page 4-11 in the user manual. The 1333 is built like a tank with a massive heat sink. I have one.

It appears that this drive is undesirable because of the external protection that is needed. I'm no marketing type but I once saw one of these drives in
a large control cabinet with all kinds of other stuff too. So perhaps it was not made for stand-alone operation to fill a need somewhere else.
 
I have one runs fine on 3 phase but nothing on single. Don't have a manual but from info I can find you are right. Guess cant make it run single phase

I use mine on single phase. Just connect per the manual.
Only takes two incoming wires from 220 Vac connected to any 2 of the 3-phase terminals. The drive peformance
will be de-rated but does not hurt anything. Except ones feeling if you are a persistent power hog...
