Life arrival signal TLARV<F043#4>
[Classification] Output signal
[Function] Posts that the service life of a selected tool group has ended.
[Output condition] This signal is set to 1 in the following cases:
- When time is specified as the life count type:
The tool group for which life management is started by the tool
change M code command (M06) is in one of the following
conditions:
i) The last tool is currently being used, and the life counter
indicates a value greater than or equal to the life value.
ii) The last tool is currently being used, and a tool skip operation
is performed.
- When frequency is specified as the life count type
The tool group for which the life counter is incremented by the
tool change M code command (M06) is in one of the following
conditions:
i) The last tool is currently being used, and the life counter
indicates a value greater than or equal to the life value.
ii) The last tool is currently being used, and a tool skip operation
is performed.
This signal is set to 0 in the following case:
- When TLARV is 1, and completion signal FIN for the tool change
M code command (M06) is set to 1.
CAUTION
1 The signal status remains as is even when the tool
group service life has been zeroed or when the CNC
is reset.
2 Once the status of this signal changes from 1 to 0
after completion signal FIN for M06 is set to 1,
specifying a T command to select the same group
again does not set this signal to 1 if the tool data is
not yet updated by, for example, the tool change
reset signal (that is, if the tool life expired state is
maintained).
