The following section discusses how to activate a tool using tool life
management. Here are some considerations to keep in mind when using
tool life management.
The system installer sets up a boundary for T--words used with tool life
management in AMP. Any T--word that is programmed less than or
equal to this number will be used as a normal tool number. Any T--word
that is programmed greater than this number is used as a tool group
number for tool management.
When a T--word is programmed using tool life management the group
that is called with the T--word is equal to the programmed T--word,
minus the value of the boundary set in AMP by the system installer. For
example if the system installer sets the boundary as 100, programming
T101 would call a tool from group 1. T102 would call a tool from
group 2, programming a T--word of 100 or less would call the specific
tool number that is programmed. This manual assumes that a boundary
of 100 is set in AMP. Refer to the system installers documentation for
details on the boundary value for a specific system.
The system installer determines in AMP when the control activates a
tool after a T--word is programmed. This manual assumes that an M06
block is required to activate the tool change process, and any T--word
that is programmed in the M06 block must be the tool number or group
number of the tool that is being replaced. This may not be the case in a
specific system (see section 20.1 for the four different types). Refer to
the system installers documentation for details on activating a T--word.
Any time after a tool from a tool group has been activated and a D-- or
an H--word is programmed, the newly programmed D or H value will
take priority. The values in the tool management table for the tool
length offset number and tool radius offset number are ignored until a
different tool is selected or that same tool is reselected.
