9.4 Tool Life Management Input/Output Signals
(1) Tool Skip Input Signal
If the tool skip input signal is “closed” during the exceution of the tool life management
function, the life status of the tool presently used is forcibly set as “skipped”.
This signal is also used to skip the tools in the specified groups. By setting these tool
group numbers by te tool skip number input signals (TGN0 to TGN7), the tools in these
groups are skipped when the tool skip input signal (TLSKP) is “closed” under the con-
dition that the parameter pm4029D1 = 1.
(2) Tool Life Count Ignore Input Signal
Tool life counting is suspended when this signal is “closed” during the execution of the
tool life management function.
(3) New Tool Selection Output Signal
When a new tool is selected in a tool group and if the status of use of
the new tool is “0”, this signal is “closed” at the same time that a T code
is output.
(4) Tool Change Output Signal
If all tools in a tool group have been used-up to life expiration during the
execution of the tool life management function, this signal is “closed”.
