set_wobbel_mode
Function Switches the Wobbel Mode on and off and defines the parameters for an ellipse-shaped
or figure-of-8 wobbel motion, see Chapter 8.4 ”Wobbel Mode”, page 232.
Call set_wobbel_mode( Transversal, Longitudinal, Freq, Mode )
Parameters Transversal Amplitude of the wobbel movement perpendicular to the momentary
direction of motion or to the one defined by set_wobbel_direction.
In bits.
As an unsigned 32-bit value.
Allowed value range: [0…131.071 (=2
17
-1)].
Excessive values are clipped.
Longitudinal Amplitude of the wobbel movement parallel to the momentary direction
of motion or to the one defined by set_wobbel_direction. In bits.
As an unsigned 32-bit value.
Allowed value range: [0…131.071 (=2
17
-1)].
Excessive values are clipped.
Freq Frequency of the wobbel movement in Hz (number of ellipses or figure-of-
8s per second).
As a 64-bit IEEE floating point value.
Allowed value range: [–6000…6000].
Larger values are clipped.
Mode Defines the wobbel shape.
As a signed 32-bit value.
= 0: Ellipse-shaped wobbel movement.
< 0: Figure-of-8 wobbel movement perpendicular to the
motion direction (vertical 8).
= 1: Figure-of-8 wobbel movement parallel to the
motion direction (horizontal 8).
> 1: “Freely definable wobbel shape”, see set_wobbel_vector.
Comments • If Mode = 0, set_wobbel_mode functions identically to set_wobbel
(see comments there).
• If Mode
 0, then a figure-of-8 wobbel movement is activated.
With figure-of-8s, broader mid-line processing can be achieved by appropriate
parameter values. If the specified transverse and longitudinal amplitudes are
identical, then the wobbel shape remains stationary in space; otherwise the
orientation of the wobbel shape follows the current direction of motion.
If set_wobbel_mode executes while a list contains a “freely definable wobbel shape”
(see set_wobbel_vector and Chapter 8.4 ”Wobbel Mode”, page 232),
then Mode > 1 selects this shape, otherwise the horizontal figure-8 shape is
selected similarly to Mode = 1. If you subsequently define a wobbel shape and
the Wobbel Mode has been activated with the parameter Mode > 1, then a switch from
the horizontal figure-8 to the wobbel shape automatically occurs. But beware: it is
then not possible to vary the power along the wobbel figure, see set_wobbel_control.
