of parameter No. 6805. The time required for single block stop, feed hold, rapid traverse,
dwell, machine lock, and interlock operations is not counted.
By setting bit 2 (LFV) of parameter No. 6801, the life count can be overridden using tool
life count override signals. An override from 0 to 99.9 can be applied. When 0 is
specified, counting is not performed.
When the tool change type is the ATC type (bit 3 (TCT) of parameter No. 5040 = 1), the
same specification method as for the M series applies. See the description for the M
series.
The following explains the specification method for the turret type (bit 3 (TCT) of parameter
No. 5040 = 0):
- Use count specification (LTM=0)
When a tool group command (T○○99 code) is specified, a tool whose life has not expired
is selected from the specified tool group, and the life counter for the selected tool is
incremented by one. Unless a tool life count restart M code is specified, selection of a new
tool and the increment operation can be performed only when a tool group number command
and a tool change command are specified for the first time since the control unit enters the
automatic operation start state from the reset state.
CAUTION
Even if the same tool group number is specified more than once in a
program, the use count is not incremented, and no new tool is
selected.
- Duration specification (LTM=1)
When a tool group command (T○○99 code) is specified, a tool whose life has not expired
is selected from the specified tool group, and tool management for the selected tool starts.
Life management (counting) is performed by measuring the time during which the tool is
actually used in the cutting mode at regular intervals (every second or 0.1 second). The life
count interval is specified by bit 0 (FCO) of parameter No. 6805. The time required for
single block stop, feed hold, rapid traverse, dwell, machine lock, and interlock operations is
not counted.
By setting bit 2 (LFV) of parameter No. 6801, the life count can be overridden using tool
life count override signals. An override from 0 to 99.9 can be applied. When 0 is
specified, counting is not performed.
