
Set "Whether to use a reference point": Move the cursor to the "Whether to use a reference point" field, enter a
numerical value (from 0 to 1) in the input field and press the <Input> key. If a reference point is to be used, it
should be switched to hand wheel mode (MPG), and the tool should be moved to the position above the tool
alignment instrument. After confirming that the tool tip is right above the tool alignment instrument, the cursor
should be moved to the "Tool alignment instrument's X coordinate reference point" field, press the 【XY axis
guide】 key to set up both "Tool alignment instrument's X coordinate reference point" and "Tool alignment
instrument's Y coordinate reference point". If a reference point is not used, please move the tool to the position
above the tool alignment instrument manually.

Replace the current tool with the longest tool, use the hand wheel to move the tool (and stop when the tool tip
is at a certain distance away from the tool alignment instrument) while making sure the tool tip is not in contact
with the tool alignment instrument. Move the cursor to the "Tool alignment starting point Z" and press the 【Z
axis guide】 key for guided input.

Replace the current tool with the shortest tool, use the hand wheel to move the tool such that the tool tip is
deviated from the tool alignment instrument by a small distance (not directly above the tool alignment
instrument), move the tool tip to a location at around 2 mm (not too much) lower than the normal position of
the tool alignment instrument and stop right here. The cursor should be moved to the "Z axis lowest machine
coordinate" field before pressing the 【Z axis guide】 for guided input. (With the protective mechanism, when
the tool alignment instrument has malfunctioned, the Z axis will not be moved further downward)

Set the numerical value for the "Return to safety point Z after tool alignment" field.

Move the tool to a proper height (higher than the tool alignment instrument) and press the 【Start tool
alignment】 key to execute the automatic tool alignment procedure. The system will fill in the designated
coordinate system with the tool length compensation value after completing automatic tool alignment.

Switch to hand wheel mode (MPG), move the tool to a position above the workpiece such that the tool tip is just
touching the surface of workpiece, and then press the 【Z gap】 key to set the gap value into the 00 coordinate
system.
《Single tool/multiple workpieces》
For the single tool/multiple workpieces method, the tool length of automatic tool alignment will be saved into the 00
coordinate system, and the gap value between the tool alignment instrument and workpiece surface should be saved into
the designated work coordinate system in accordance with Z axis gap settings. The operation is described below:
