6811 Tool life count restart M code
[Data type] 2-word
[Valid data range] 0 to 255 (not including 01, 02, 30, 98, and 99)
When 0 is specified, it is ignored.
• For tool life management:
1 When the life is specified by the number of times, the tool
exchange signal is output when a tool life count restart M
code is specified if tool life of at least one tool group is
expired. A tool in life is selected in the specified group
when a T code command (tool life management group
command) is specified after the tool life count restart M
code is specified. A tool life counter is then incremented by
one.
2 When the life is specified by time, a tool in life is selected
in the specified group when a T code command (tool life
management group command) is specified after the tool life
count restart M code is specified.
• For the tool management function:
When a tool life count restart M code is specified, the counting
of the life of the tool attached to the spindle position is started.
1 When the life is counted by the number of times, the life
count target is switched to the tool attached to the spindle
position, and the life count is incremented by 1.
2 When the life is counted by time, only an operation for
switching the life count target to the tool attached to the
spindle position is performed.
When the tool attached to the spindle position is not a tool life
management target, no operation is performed.

Remaining tool life (use count)
[Data type] Word
[Unit of data] Count
[Valid data range] 0 to 9999
This parameter sets a remaining tool life (use count) used to output the
tool life arrival notice signal TLCHB <F064#3> when the tool life is
specified as a use count.
NOTE
1 When the remaining life (use count) of a selected
tool reaches the value specified with this
parameter, tool life arrival notice signal TLCHB is
output to the PMC.
2 If a value greater than the life of a tool is specified
with this parameter, the tool life arrival notice signal
TLCHB is not output.
