I bought an ABB vfd years ago to power an old milling machine, single phase to three phase, it was a bit of a pain to set up but i got it done. I have fitted a bridgeport vari-speed head to the mill and now need to run the bridgeport motor in both directions.
But it is resisting all attempts to work for me. No matter what i do i can only get the mill spindle to turn in one direction.
It is an ACS50 made by ABB, has anyone any experience of these particular inverters, that could give a bit of help ? I need guidance on how to wire a start-stop-reverse switch. I am following the diagram in the manual (pdf below) and it simply will not work.
