Input options
Soft key Function
Directly transfer the actual position of the tool (the
measuring dial) as the new preset: This function
only saves the preset in the axis in which the
cursor is currently hovering.
Assign any value to the actual position of the tool
(the measuring dial): This function only saves the
preset in the axis in which the cursor is current-
ly hovering. Enter the desired value in the pop-up
window
Incrementally shift a preset already stored in the
table: This function only saves the preset in the
axis in which the cursor is currently hovering. Enter
the desired corrective value with the correct sign in
the pop-up window. If inch display is active: Enter
the value in inches, and the control will internally
convert the entered values to mm
Directly enter the new preset without calculation
of the kinematics (axis-specific). Only use this
function if your machine has a rotary table, and you
want to set the preset to the center of the rotary
table by entering 0. This function only saves the
value in the axis in which the cursor is currently
hovering. Enter the desired value in the pop-up
window. If inch display is active: Enter the value in
inches, and the control will internally convert the
entered values to mm
Select the BASE TRANSFORM./OFFSET view. The
standard BASE TRANSFORM. view shows the X,
Y and Z columns. Depending on the machine,
the columns SPA, SPB, and SPC are displayed in
addition. The control saves the basic rotation here
(with the Z tool axis the control uses the SPC col-
umn). The OFFSET view shows the offset values
for the preset.
Write the currently active preset to a selectable line
in the table: This function saves the preset in all
axes, and then activates the appropriate row in the
table automatically. If inch display is active: Enter
the value in inches, and the control will internally
convert the entered values to mm
