SENS

Sensitivity (aggressiveness) of feedback control. 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 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.
