2. Screen Operation of A985GOT
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.
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.
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 display reaches the service lifetime display, or when the count display
exceeds the service life count display, the corresponding tool No. (#) on the TOOL LIFE DATA
screen is highlighted.
The usage time and count are incremented, but no alarm is output to the user PLC, and the tool
No. (#) on the TOOL LIFE DATA screen is not highlighted.
