We have CNC(Butler) with Heidenhain control having Siemens servo drives.
Problem comes at the time of referencing.At the time of referencing of X axis(horizontal axis for travel)
Y axis(verical for Up-down) coming down suddenly,we need to press emergency stop quickly to prevent any damage.
Someone told us the problem might be in X-axis,it may be jammed not getting freely move.So we opened the whole ball screw assembly for travel(x axis) lubricate it thoroughly & refix it.Stii Y axis coming down rapidly at the time of referncing x-axis.On screen error displyed "Gross position error D"
sometimes "Gross position error A".Facing big trouble...please help!
Thank you!
