Function
This parameter determines how a T-word may be programmed in
conjunction with an M06 code. There are 4 methods available:
Method
Description
Return tool in M06
With this method, the T-word to be activated is programmed in a
block that does not contain an M06. The T-word is stored until
some later block that contains an M06. When the M06 is
executed, the currently active tool is replaced with the last tool
number programmed with a T-word. With this method, the tool
number (or group number) that is being replaced as the active tool
must be programmed in the block that contains the M06
command. If the M06 block does not contain the previously active
tool number/group number, or if the wrong number is programmed
with the M06, the control will generate an error.
Next tool in T-word
This method is identical to the “Return tool in M06” method with
the exception that the block containing an M06 cannot contain a
T-word. The new tool/group number is programmed in some block
before the M06 block. It is not necessary to program the
previously active tool number/group number in the M06 block.
M06 Required
This method defines that a tool is only activated in an M06 block.
A T--Word that is programmed by itself becomes the next tool
activated at an M06 block. Programming an M06 by itself activates
the next tool. If a T--word is programmed in an M06 block, that
T--word is used as the active tool and any other unactivated
T--word is discarded.
Activate Tool in T-word
For this method, no M06 needs to be programmed to change
tools. When the T-word is executed, a tool change occurs. It is
not necessary to program the previously active tool number/group
number in the M06 block.

Notes
This is a global parameter; the value set here applies to all axes. For Dual
Processing controls, this is a per process parameter. The value set in the
parameters applies to all of the axes assigned to that process. This is a mill
only parameter.
