6. G, F signals relevant to tool life function
a） Tool change signal TLCH（F064＃0）
［Type］ output signal
［Function］ inform PLC that the last tool life ends of in this group
［Output condition］ the signal is set to 1, the last tool life in one group ends, all other tool
life ends.
b） New tool selection signal TLNW（F064＃1）
［Type］ output signal
［Function］ inform a new tool in some tool group has been selected
［Output condition］ the signal is set to 1 and a new tool in some tool group has been
selected.
c） Tool change reset signal TLRST（G048＃7）
［Type］ input signal
［Function］ clear all execution data
［Operation］ when the signal is set to 1, the control unit clears the used tool life data of in
all groups; the tool state is reset to the unused.
Note: when the automatic operation signal OP is “0”, the tool change reset signal TLRST is valid.
d） Tool skip signal TLSKP（G048＃5）
［Type］ input signal
［Function］use the following two methods to change the tools which have not reached
the
life:
1） When LIFJ（NO.2#4）is set to 1，the selection signals of the tool group number
（G47#0~#4）specify the tool group number, then, the tool skip signal TLSKP
becomes “1”，the next T command skips the tool which is being used of the
current group, and the tool which life has not reach in the group specified by
G47#0~#4 is used.
2）When LIFJ（NO.2#4）is set to 0，the group numbers specified by the tool group
number signal （G47#0~#4）are invalid, the tool skip signal TLSKP becomes “1”,
the machine skips to the next tool in the current used tool group.
［Operation］when the signal is set to 1, the operation described in [Function] is executed.
Note: When cycle start light signal(STL) and feed pause light signal(SPL) must be “0”, inputting
TLSKP signal
is valid.
e） Tool group number selection signal TL01~TL16（G47#0~#4）
［Type］ input signal
［Function］ when TLSKP is input, using the tool group selection signal TL01~TL16
specifies the tool group number with the binary system. The specified tool
group number = G47#4~#0＋1.
［Operation］ specify the selected tool group
