Manual and Handwheel Travel (H1)
Contour handwheel/path default using handwheel (optional for SINUMERIK 840D)
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 (contour-handwheel-simulation negative direction)
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
If the block-change criterion (IPO end) is reached, the program advances to the next
block (response identical to G60).
→ 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.
The function is activated/deactivated via interface signal
DB21, ... DBX30.0, 30.1, 30.2 (activate handwheel x as a contour handwheel)
The contour handwheel can be activated in the NC program non-modally using FD=0,
that is, velocity F from the block before the contour handwheel applies in the following
block without the need for additional programming.
Note
If no feedrate was programmed in the previous blocks, a corresponding alarm is output.
FD and F cannot appear in the same NC block (triggers an alarm).
