TOOL CHANGE RESET

(L SYSTEM)
[Function]
This signal is used to clear all tool usage data in the group of the lathe system tool life management
II function.
[Operation]
Select whether the group to be cleared is all groups which have exceeded the life or specific group
with the tool group No. designation (file register R930).
When the next group is selected after this signal is input, the head tool of that group will be
selected.
(Note) The usage data will be counted in respect to the tool used when the signal is input until the
tool change is reset or until the next tool is selected when tool skip is carried out on the
currently selected group. Thus, when changing the selected tool along with the signal input,
select the group beforehand. However, if there is no movement command up to the next
group selection after this signal is input, a tool may not be selected because of the
preceding process. In this case, turn the "Recalculation request (CRQ)" signal ON before
selecting the group to invalidate the details of the preceding process.
[Related signals]
(1) Recalculation request (CRQ: Y72B)
(2) Tool group No. designation (R930)
