Tool wear monitoring
Activate cut-related tool wear monitoring by entering a value not
equal to 0 in the AFC-OVLD1 column in the tool table.
The shutdown response depends on the AFC.TAB column OVLD.
In conjunction with cut-related tool wear monitoring the control
only evaluates the two options M and L in the OVLD column,
whereby the following responses are possible:
Pop-up window
Lock current tool
Insert replacement tool
If the AFC.TAB columns FMIN and FMAX each have a
value of 100%, adaptive feed control is deactivated but
cut-related tool wear monitoring remains active.

and page 538
Tool load monitoring
Activate cut-related tool load monitoring (tool breakage control) by
entering a value not equal to 0 in the AFC-OVLD2 column in the
tool table.
As shutdown response, the control always executes a machining
stop and locks the momentary tool.
If the AFC.TAB columns FMIN and FMAX each have a
value of 100%, adaptive feed control is deactivated but
cut-related tool load monitoring remains active.
