Selecting the axis to be moved
You can activate directly through the axis address keys the principal
axes X, Y, Z and three other axes defined by the machine tool
builder. Your machine tool builder can also place the virtual axis VT
directly on one of the free axis keys. If the virtual axis VT is not on
one of the axis selection keys, proceed as follows:
Press the handwheel soft key F1 (AX): The TNC displays all
active axes on the handwheel display. The currently active axis
blinks
Select the desired axis with the handwheel soft keys F1 (->) or
F2 (<-) and confirm with the handwheel soft key F3 (OK)
Setting the handwheel sensitivity
The handwheel sensitivity specifies the distance an axis moves per
handwheel revolution. The sensitivity levels are pre-defined and are
selectable with the handwheel arrow keys (only when incremental
jog is not active).
Selectable sensitivity levels: 0.01/0.02/0.05/0.1/0.2/0.5/1/2/5/10/20
[mm/revolution or degrees/revolution]
