Tool life arrival notice signal TLCHB <Fn064#3>
[Classification] Output signal
[Function] If the tool life management B function is enabled (bit 4 (LFB) of parameter No.
6805 = 1), a remaining life value until selection of a new tool may be set. Then,
when life counting shows that the remaining life of a group (the life value
minus the life counter value) becomes equal to or smaller than the remaining
life setting, the tool life arrival notice signal is output to report the end of the
tool life in advance.
The tool life arrival notice signal may be output for each tool or for the last tool
in a group, according to the setting of bit 4 (ARL) of parameter No. 6802.
As the remaining life setting, the setting in parameter Nos. 6844 and 6855 or
the value registered as tool life management data is used, one of which is
selected by bit 3 (GRP) of parameter No. 6802.
[Output condition] The signal is set to "1" when:
- If bit 7 (RMT) of parameter No. 6802 = 0
The remaining life (the life value minus the life counter value) is smaller than or equal to
the remaining life setting.
- If bit 7 (RMT) of parameter No. 6802 = 1
The remaining life (the life value minus the life counter value) equals the remaining life
setting.
The signal is set to "0" when:
- If bit 7 (RMT) of parameter No. 6802 = 0
The remaining life (the life value minus the life counter value) is greater than the remaining
life setting.
- If bit 7 (RMT) of parameter No. 6802 = 1
The remaining life (the life value minus the life counter value) does not equal the remaining
life setting.
NOTE
1 The signal status changes when life counting is performed.
2 When using a life count override, set bit 7 (RMT) of parameter No.
6802 to 0.
3 When the life count is specified by duration, the unit of the remaining
life and remaining life setting to be compared varies depending on the
life count interval (bit 0 (FCO) of parameter No. 6805). If the life is
counted every second, the unit of the values to be compared is one
minute; if the life is counted every 0.1 second, the unit of the values to
be compared is 0.1 minute.
