The tool compensation amount screen is displayed.
The tool compensation number of the selected tool is
displayed at the top, and the cursor is located on the first
line.
<Note>
If the parameter "#8972 T code offset disp" is set to
"0", the tool compensation number of selected tool
is not displayed at the top. Locate the cursor onto
the tool compensation number of the tool to be mea-
sured.
When you enter "Z", the cursor is moved to the Z axis col-
umn.
<Note>
If you input an axis name that does not exist, the cur-
sor does not move.
The second and subsequent characters are not con-
sidered to be the axis name and, therefore, the cur-
sor does not move. (Example: If you enter "XZ", the
cursor moves on the X axis, but the cursor does not
move on the Z axis.)
Also, if anything other than tool length data is dis-
played, the cursor does not move even when the
first input value is the axis name.
Value "Z0." is displayed in the input column.
The measured value (Z axis machine position - Input val-
ue (0)) is set in the tool length data at the cursor position.
The input column is cleared.
