27 Setting the Machine Error Compensation
(2) Memory-type relative position error compensation
This function compensates the relative position error between two orthogonal axes caused by deflection of the
moving according to the specified parameters.
You can set compensation amount in the compensated axis direction for each division point obtained by equally
dividing the machine coordinates of the basic axis. (See the figure below.)
"Basic axis" refers to the one axis of two orthogonal axes on which relative position compensation is made. This
axis is used as the criterion for relative-error measurement. "Compensation axis" refers to the coordinate axis that is
orthogonal to the basic axis. The compensation is actually made for this coordinate axis.
Machine position between division points "n" and "n+1" is smoothly compensated by the linear approximation of the
compensation amount.
