3. Tool Offset (L system)
3.2 Tool Length Data
I-93
Refer to "3 (II). Tool Offset (M system)" for M system.
(4) Explanation of operations
(a) Setting the tool compensation amount
1) Zero point return
After turning the power ON, establish the coordinate system by carrying out dog-type zero point return.
When using the absolute position detection specifications, carry out initialization if the absolute
position is not established.
2) Select the mode
Set the mode selection switch to the manual mode (either [handle], [jog] or [rapid traverse]).
3) Input the tool measurement mode signal
Set the tool measurement mode signal to "1".
The tool measurement mode is entered with steps 1), 2) and 3).
4) Confirm measurement basic value (sensor position)
The following parameter must be set before carrying out tool setter operations.
#2015 tlml–, #2016 tlml+
(sensor position) Axis specification parameter p. 2
Z

Zm
Z axis
Xm
X axis
Xm : X axis – sensor machine coordinate value (position measured by moving in – direction)
→ #2015 tlml– X axis
Zm : Z axis – sensor machine coordinate value (position measured by moving in – direction)
→ #2015 tlml– Z axis
Xp : X axis + sensor machine coordinate value (position measured by moving in + direction)
→ #2016 tlml+ X axis
Zp : Z axis + sensor machine coordinate value (position measured by moving in + direction)
→ #2016 tlml+ Z axis
If the axis to be measured is the additional axis, the axis set with #2015 tlml-/#2016 tlml+ will differ
according to the additional axis tool compensation operation selection parameter (#1520 Tchg34).
#1520 Tchg34 #2015 tlml–/#2016 tlml+ setting
0 3rd axis
1 4th axis
5) Select the tool
Select the tool to be measured.
Set the compensation No. of the tool to be selected as a BCD code in R2970.
Set the compensation No. of the wear data to be cleared after measurement as a BCD code in R186.
(The tool No. data is input from the PLC to the NC.)
