2.3.4.3 Setting Tool Life Management Data
(1) T
o set tool life management data, set the tool No. in # ( ). Then set the tool service lifetime and
service life count data in the corresponding setting areas, and press the [INPUT] key.
(2) The operations in (1) update the tool life management data display, increment the tool No. in # ( ) by 1,
and deletes the service lifetime (life count) data in ( ).
(3) If a tool No. and tool life management data is set for a tool No. other than the ones displayed, the
screen will change to one corresponding to the set tool No. when the [INPUT] key is pressed once. The
tool life management data can be set by pressing the [INPUT] twice.
(4) The tool No. that appears in # ( ) can be continually incremented or decremented by pressing the [↑]
and [↓] keys.
2.3.4.4 Erasing Tool Life Management Data in Display Screen Units
T
en set
s of tool life management data appear in one screen. All the displayed tool life management data
(time-used, time-max, count-used, count-max) can be set to 0 by pressing the [INPUT] key, and then
pressing the [SHIFT] [C.B CAN] key and [INPUT] key.
2.3.4.5 Cautions
(1)
The
cumulative time (count) is incremented, even if the service lifetime (service count) is set to "0".
Note that a warning (tool life expiration signal: X62E) is not output.
(2) For tool life management by time, a warning will not be output to the PLC if the usage time reaches the
service lifetime during cutting. Instead, the warning will be output when the next tool selection
command is issued. During that interval, the usage time will continue to increment.
(3) When there are 20 offset pairs, the No. of tools whose lifetime can be managed is 20.
(4) The TOOL LIFE screen cannot be selected in systems without the tool life management function. If the
tool life management menu key is pressed, alarm "E06 NO SPEC" will occur and the screen will not
change.
(5) If a tool selection (T) command is carried out during cutting feed modal, the count will be incremented
at that time.
