1.1.5 Tool Life Count Restart M Code
Explanation
If the life count is specified by use count, the tool change signal is output if the life of at
least one tool group has expired when a tool life count restart M code is specified. After
the tool life count restart M code is specified, a tool group command (T code) selects, from a
specified group, a tool whose life has not expired, and the next tool change command (M06)
increments the tool life counter by one. This enables the tool life to be counted by a tool
change command (M06) even when the command is not the first tool change command
(M06) issued since the CNC enters the automatic operation start state from the reset state.
The tool life count restart M code is specified in parameter No. 6811.
Example: Suppose that M16 is a tool life count restart M code and that the tool life
management ignore number is 100.
Also suppose that the life count is specified by use count.

When the tool change type is the ATC type (bit 3 (TCT) of parameter No. 5040 = 1), the
same specifications as for the M series apply. See the description for the M series.
The following explanation assumes that the tool change type is the turret type (bit 3 (TCT)
of parameter No. 5040 = 0).
If the life count is specified by use count, the tool change signal is output if the life of at
least one tool group has expired when a tool life count restart M code is specified. When a
tool group command (T code) is specified after the tool life count restart M code is specified,
