Hi all...
this morning my 5-axis machine didn't want to reference--- it gives me the 411 servo alarm: B axis excess err... after I reset it, I can move the B axis to the opposite direction and if it goes too far I get the alarm 1002 overtravel hardware or AP69.
it seems that the B axis just lost where it is and the travel range is much small now... Can't figure out what it is...
anyone can help me out? do i have to replace a battery on this servo thing? where is the battery?
machine specs --- vertical 5-axis with fanuc series 16i-MB
5th axis --- LEHMANN EA-407 table with single spindel
5th axis --- servo type A860-2005-T301
thanks all!
