Segmentation Error

(Segmented error compensation)

For the operation method, refer to the instruction

manual or the simple manual (Segmented error

compensation).

Segmented error compensation function uses a scale

with reference point to correct mechanical errors for

each interval.

The range that can be corrected is the range of the

counter display based on the reference point position.

In order to use this function, it is necessary to

measure the section error of the machine with a laser

interferometer, length reference device, etc. in

advance.
