3. BASIC OPERATIONS
NOTE
If the following operations 1 and 2 are repeated at the occurrence of an overflow when
using the AT100 series linear scale, an overflow error (Error30) may occur even if a value
smaller than the maximum preset value shown below is preset.
If presetting a large value and error occurrence are repeated multiple times, the
above-mentioned situation will be encountered due to overflow of offsetting in the
counter. If this is the case, perform offset correction procedure described below for the
axis where Error30 has occurred, then the normal state will be restored.
Exercise care when presetting a large value exceeding the maximum preset value.
• Operation at the occurrence of an overflow
1. Preset a value (larger than the maximum preset value).
2. An error occurs. (E.g. Error20)
3. Repeat steps 1 and 2.
• Maximum preset value

+200.00000 inch
• Overflow correction procedure
a. Press the [▼], [SET], [X] (or [Y] or [Z]), [0], and [LOAD] keys in this order.
b. Move the linear scale to pass through the origin mark.
For the user who is using the KA counter with a minimum resolution of 0.0005 or
0.0001mm.
When data to be preset is smaller than or equal to 1m, the display method of the most
significant digit and the sign differ from the normal preset. It alternately displays the sign
and the most significant digit as shown in the figure below.
• Example) +9999.9999
Alternately displays a cursor and a numeric.
