Selecting the axis to be moved
You can activate the principal axes X, Y, Z and three other axes
defined by the machine manufacturer directly through the axis
keys. 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 keys, proceed as follows:
Press the handwheel soft key
F1
(
AX
)
The control shows all active axes on the handwheel display. The
currently active axis flashes.
Select the desired axis with the handwheel soft keys
F1
(

F2
(

) and confirm with the
F3
(

) handwheel soft key
Refer to your machine manual.
The machine manufacturer can also configure the
turning spindle (option number 50) as an optional axis.
You can select whether only the position display should be shown,
or the position display with the offset value from the global

Setting the handwheel sensitivity
The handwheel sensitivity determines which path an axis takes per
revolution of the handwheel. The sensitivity levels are predefined
and are selectable with the handwheel arrow keys (only when
incremental jog is not active).
Selectable sensitivity levels:
0.001/0.002/0.005/0.01/0.02/0.05/0.1/0.2/0.5/1 [mm/revolution or
degrees/revolution]
Selectable sensitivity levels:
0.00005/0.001/0.002/0.004/0.01/0.02/0.03 [in mm/revolution or
degrees/revolution]
