POS soft key.
 Move the touch probe to a starting position near the
touch point.
 Select the probe axis and direction in which you wish
to set the datum, such as Z in direction Z–. Selection
is made via soft keys.
 To probe the workpiece, press the machine START
button.
 Datum: Enter the nominal coordinate and confirm your
entry with SET DATUM, or write the value to a table
(see “Writing the measured values from touch probe
cycles in datum tables,” page 30, or see “Writing the

bases the probed value on the active preset (or on the
reference point most recently set in the Manual operating
mode), although the datum shift is included in the position
display.
