In the AFC.TAB table you can define as many control
settings (lines) as desired.
If there is no AFC.TAB table in the
TNC:\table
directory,
the control uses a fixed control setting for the teach-
in cut. If, alternatively, a tool-dependent reference
power value exists, the control uses it immediately.
HEIDENHAIN recommends to use the AFC.TAB table in
order to ensure a safe and well-defined operation.
Proceed as follows to create the AFC.TAB file (only necessary if the
file does not yet exist):
Select the
Programming
operating mode
To call the file manager, press the
PGM MGT
key
Select the
TNC:\
directory
Create a new AFC.TAB file
Press the
ENT
key
The control displays a list with table formats.
Select the AFC.TAB table format and confirm with the
ENT
key
The control creates the table that contains the control settings.
