table until the lathe tool is aligned with point O, and zero
the X axis, Y axis)
3) The machine table is moved when power is off;
4) Power on, switch to ABS coordinate. The DRO maybe
displays as the right.
5)
Search the RI of X axis and Y axis. After RI is found, the
ABS coordinate is restored.
6)
Align the lathe tool with point O, “0.000” is displayed in
X window and Y window, which means the point O is the
origin and the ABS coordinate is restored.
NOTE:
The linear scale has a RI every 50 mm. For the sake of search identical RI, move the scale around the red
mark “
” to search RI.

Clear the Error message
If ERROR message is enabled, the message window will display “E1” if the signal of phase A and
phase B of the linear scale changes at the same time; the message window will display “E2” if the linear
scale runs too fast; the window will display “E3” if these two conditions occur simultaneously. When error
information appears, the display value has an error of 1-2 count. So users need search RI to restore ABS
coordinate. If you think that doesn’t affect your work, press
AC
to clear error message and continue your
work. .
Example : When signal of A phase and B phase is same in Y
axis the window displays as the right figure.
Press
AC
to clear the error information. Y window
displays the value, but it is error. The difference between the
display value and the true value is about 1- 2 times of
resolution. For instance, the resolution of scale is 5µm; the
difference is 5-10µm.

Lathe Function
As the right figure, if two scales are installed
in one axis, the position of the work-piece should
be the sum of these two values (X+Y) in this
