SENS Sensitivity (aggressiveness) of regulation. A value
between 50 and 200 can be entered. 50 is for slow
control, 200 for a very aggressive control. An aggressive
control reacts quickly and with strong changes to the

100
PLC Value that the TNC is to transfer to the PLC at the
beginning of a machining step. The machine tool builder
defines the function, so refer to your machine manual.
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:\ directory, the TNC
uses permanently defined internal control settings for the
teach-in cut. It is best, however, to work with the AFC.TAB
table.
