10.2.5 Tool Life Count Restart M Code
Explanations
When the life count type is frequency, a tool-change signal is output if
at least one tool group has expired when the tool life count restart M
code is specified. After the tool life count restart M code is specified,
the 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 1. This makes it possible to count
the tool life using commands other than the first tool-change command
(M06) since the CNC entered the automatic operation start state from
the reset state. The tool life count restart M code is specified using
parameter No. 7442.
NOTE
1 The tool life count restart M code is treated as an M code
without buffering.
2 When the life count type is frequency, a tool-change signal is
output if at least one tool group has expired when the tool life
count restart M code is specified. When the life count type is
time, no operation is performed when the tool life count restart
M code is specified.
Example : Suppose that M16 is the tool life count restart M code and 100 is the tool life
management invalidation number. Also suppose that the life count type is
frequency.
