Hi I am having problems with a hitachi seiki 3ne with fanuc 6t control. the machine suddenly started to mis position / miscount on the x axis
I thought this might be an encoder issue so I changed it for a used one, and the problem still persists,
even with the servo disconnected mechanically when I jog the axis using mpg it will not return to the original position.
my question is : could this be a set up problem or u.s. servo control card thanks in advance for any help
