Traversing direction
The traversing direction depends on the direction of rotation:
● Clockwise
● Counterclockwise
Activation of the function
The function can be activated via interface signals or via the NC program:
● Activation via interface signal
● Activation via the NC program
Contour-handwheel simulation
When the contour handwheel is activated, it can also be simulated.
After activation via interface signal
DB21, ... DBX30.3 (contour-handwheel simulation),
the feedrate is no longer defined by the contour handwheel; the programmed feedrate is
used instead.
The direction is also defined via an interface signal:
DB21, ... DBX30.4 (negative direction simulation contour handwheel)
When the simulation is deselected or the direction is changed, the current movement is
decelerated using a braking ramp.
Note
The override is effective as for NC-program execution.

→ Results in travel in the programmed direction
Here, the axes can only traverse to the appropriate block start. Pulses are not collected if
the handwheel continues to rotate.
Switching-in/switching-out is realized via the interface signal:

The contour handwheel can be activated in the NC program non-modally using
