Well this interview lasted four hours and i really couldnt get a chance to ask any questions, they just want to sell you the company. Aparantly its a good thing they arent making money because otherwise they would be paying tax?! They must think im a retard to think its good not to make a profit! I was told they have spend 10 years working on the automation of their warehouses and basically it didnt work for 6 of those years because the idiotic management outsourced the programming to different firms. As you can guess when they bolted it together it didnt work. The last 4 years since then they have something they call "unified code" and now write all the function blocks for the plcs. These blocks have no servo control, just single bit i/os all the servo systems must be third party. Basically they wasted millions of bankers money and still cant get it run properly/efficiently to make profit.

What thinking process or series of steps would you go through if you were operating a stepper motor and you encounter one of the four leads to the stepper motor was in some way damaged or disconnected but you don't know how or why. You can't look to see or try to fix it, so what would you do from a control standpoint to look into the issue.
