Position Error Compensation
24.1.1 Outline
(1) Memory-type pitch error compensation
According to the specified parameters, this method compensates an axis feed error caused by a ball screw pitch
error, etc.
You can set compensation amount for each division point obtained by equally dividing the machine coordinates
based on the reference position. (See the figure below.)
The compensation amount can be set by either the absolute or incremental amount method. Select the method with
"#4000 Pinc".
Machine position between division points "n" and "n+1" is smoothly compensated by the linear approximation of the
compensation amount.
