SENS Sensitivity (aggressivity) of the control. Input possible
between 50 and 200. 50 is for slow control, 200 for a
very aggressive control. An aggressive control reacts
quickly and with strong changes to the values, but it
tends to overshoot. Recommended value: 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.
