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 (->) or
F2 (<-) and confirm with the F3 (OK) handwheel soft key
Setting the handwheel sensitivity
The handwheel sensitivity determines which path an axis takes per
revolution of the handwheel. The sensitivity levels are predefined

incremental jog is not active).
