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 tool length
compensation value into Z length offset of the tool length offset number corresponding to the tool after
completing automatic tool alignment.

Set "Gap setting for the work coordinate system": Move the cursor to the "Work coordinate system" field, enter a
numerical value (from 54 to 59) in the input area and press the <Input> key. If the extended coordinate system
G54 is being used, the "Work coordinate system" field should be set as G54 before moving the cursor to the next
field (extended coordinate system), enter a numerical value (1 to 100) in the input area and pressing the <Input>
key.

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 designated
coordinate system.
Note: The setting method for tool length compensation values for each tool and the gap value for each workpiece are as
follows:
For example: There are two workpieces, one is based on the G55 coordinate system (workpiece A) and the other is based
on the G54P100 coordinate system (workpiece B). There are two tools T1 and T2 corresponding to tool offsets H1
and H2, and it also uses the automatic tool change (M6Tx) function.
Set the tool length compensation value for tool T1:
i. Move the cursor to the "Tool number" field, enter the value 1 in the input area and press the <Input> key.
ii. Move the cursor to the "Is automatic tool change required" field, enter the value 1 in the input area and
press the <Input> key.
Move the tool to a proper height (higher than the tool alignment instrument) and press the 【Start tool
iii.
alignment】 key to execute the automatic tool alignment procedure. The system will conduct the
automatic tool alignment procedure after automatically changing tools at T1. The system will then fill in
the tool length compensation value into the Z length offset of tool length offset number 1 corresponding
to the tool after completing automatic tool alignment.
Set the tool length compensation value for tool T2:
i. Move the cursor to the "Tool number" field, enter the value 2 in the input section and press the <Input>
key.
ii. Move the cursor to the "Is automatic tool change required" field, enter the value 1 in the input area and
press the <Input> key.
Move the tool to a proper height (higher than the tool alignment instrument) and press the 【Start tool
iii.
alignment】 key to execute the automatic tool alignment procedure. The system will conduct the
automatic tool alignment procedure after automatically changing tools at T2. The system will then fill in
the tool length compensation value into the Z length offset of tool length offset number 2 corresponding
