management methods can be selected.

Set to "0".
(1) Tool life management by time
The cutting time (G01, G02, G33, etc.) after a tool selection (T) command is carried out is
incremented to the usage time corresponding to the commanded tool.
If the usage time reaches the service lifetime when a tool selection command is executed, a
warning is output to the user PLC.
When the usage time reaches the service lifetime, the corresponding tool No. (#) on the TOOL
LIFE DATA screen is highlighted.
(2) Tool life management by count
The count for the commanded tool is incremented when the first cutting feed starts after a tool
selection (T) command is carried out. If no cutting feed is executed after the selection of a tool, the
count is not incremented.
If the count equals the service life count for the commanded tool when a tool selection command
is executed, a warning is output to the user PLC.
When the count exceeds the service life count (when the cutting feed starts after a tool selection
command), the corresponding tool No. (#) on the TOOL LIFE DATA screen is highlighted.
(3) Tool life management by time and count
The tool life is managed simultaneously by time and count.
If the usage time reaches the service lifetime, or the count equals the service life count for the
commanded tool when a tool selection command is executed, a warning is output to the user
PLC.
When the usage time reaches the service lifetime, or when the count exceeds the service life
count, the corresponding tool No. (#) on the TOOL LIFE DATA screen is highlighted.
(4) No management
The usage time and count are incremented, but no warning is output to the user PLC, and the tool
No. (#) on the TOOL LIFE DATA screen is not highlighted.
3.4.2 Conditions for Counting (incrementing)
The usage time (or count) is incremented when a cutting feed (G1, G2, G3, G33) is executed. Note
that they are not incremented in the following conditions:
• When the base specification parameter "#1103 T-Life" is OFF.
• During machine lock
• During miscellaneous function lock (input signal from the PLC)
• During dry run
• During single block operation
• When the count ON signal of the data used is OFF. (Input signal from the PLC)
