I am working in China at the moment commissioning a new automation system here. They have, amongst other things, a revolve built into the rear wagon. As I cant speak the same language as anyone else onsite I cant find out why there is a limit switch that marks 'zero' position.
The machine has an encoder and I can tune it in degrees or millimeters or what ever so why wouldn't the operator just be allowed to 'move up 180' or 'move down 720' - who cares where 0 is? As long as it really turns 180 degrees when asked why not just use the position it is in on the day of the bump-in - irrespective of the position reading. Mechanically there is no reason it cannot revolve infinately so can anyone thing of a good reason to have a zero position marker - and would you want me to stop the machine there or just let you know it has past that position with an indicator on the operator interface? Or should I just ignore it?
Any thoughts welcome. Cheers all.
