Tool Length Offset
When the control is in 7300 mode, tool length offsets are activated in the
same manner as on the 7300. The control supports 1- through 4-digit
T-words, and through AMP configuration, you have the flexibility of
specifying how the control activates offsets.
We recommend that you use this set-up when running your control in 7300
mode:
Set This Tool Length Offset Parameter:
To:
Explanation:
Tool Geometry Mode (AMP [202]):
immediate shift/immediate move
once the offset is programmed, the geometry offset
is activated immediately and the coordinate system
gets shifted immediately.
Tool Wear Mode (AMP [203]):
immediate shift/immediate move
once the offset is programmed, the wear offset is
activated immediately and the coordinate system
gets shifted immediately.
Tool Offset Cancel (AMP [204]):
cancel geometry & wear
both the geometry and wear offsets are cancelled
when the active offset is cancelled.
T-code Format (AMP [205]):
2-digit geometry & wear
The 2 right-most digits are used for geometry &
wear; and the leftover are used for tool number.
Example: T10 activates geometry offset 10 and
wear offset 10 on tool number 0.
Example: T915 activates geometry offset 15 and
wear offset 15 on tool number 9.
If the Tool Life Management option is present, set the following AMP
parameters for 7300 compatibility:
Set This Tool Length Offset Parameter:
To:
Explanation:
Tool Number/Group Boundary (AMP [131]):
9799
specify the division between ordinary tool numbers
and tool life groups.
T-word Programming Method (AMP [132]):
next Tool in T-word
for this method, the T-word to be activated is
programmed in a block that does not contain an
M06.
For systems with the Tool Life Management option, the T-word is limited
to four digits in the range of 1 to 9799.
Refer to the AMP manual for details on any of the above AMP parameters.
Important: When 7300 mode is active on the control, automatic tool
changing requires the proper PAL interface and may require changing the
AMP parameters described above. The random tool feature of the control
is also available to interface with special tool changers.
