Handwheel assignment
The assignment of the connected handwheels to the axes is analogous to the "Handwheel
travel in JOG (Page 154)" via the user interface or via the PLC user interface with one of the
following interface signals:
● Machine axes:
● Geometry axes:
If handwheel override is programmed for an axis to which no handwheel is assigned, a
distinction is made between the following cases:
● For velocity override:
● For path definition:
Handwheel weighting
The traverse path of the axis that is generated by rotating the handwheel by one detent
position is dependent on several factors (see Section "Handwheel travel in JOG
(Page 154)"):
● Selected increment size:
● Weighting of an increment:
● Number of handwheel pulses per detent position:
For example, the axis traverses by 0.001 mm per handwheel detent position if machine
function INC1 and the default setting of the above machine data are selected.
In the case of velocity override, the velocity results from the traverse path covered using the
handwheel within a certain period of time.

The axes traverse at the programmed velocity.
A self-acknowledging alarm is output (without response).
No traversing movement is performed because the velocity is zero.
A self-acknowledging alarm is output (without response).
Note
When the velocity override is applied to path axes, only the handwheel of the 1st
geometry axis acts on the path velocity.
