Command
para_mark_abs
Function Moves the laser focus at mark speed along a 2D vector from the current position to the
specified position (absolute coordinate values) within a 2D Image Field. Simultaneously
varies the signal parameter selected by set_vector_control linearly to the specified value.
Call
para_mark_abs( X, Y, P )
Parameters
X
Absolute x coordinate of the mark vector end point. In bits.
As a signed 32-bit value.
Allowed value range: [–268,435,456…+268,435,455].
Out-of-range values are clipped to the boundary values.
The complete value range is only usable as a virtual Image Field for example,
for (enabled) Processing-on-the-fly applications.
Y
Like
X
(analogously).
P
End value of the signal parameter.
As an unsigned 32-bit value.
Allowed values: dependent on the selection made by set_vector_control
(
Ctrl
parameter), identical with set_vector_control (
Value
parameter).
Comments • If “vector-controlled laser control” has not been previously activated by
set_vector_control, then para_mark_abs behaves like mark_abs (see comments
there). The parameter
P
is then ignored.
• If “vector-controlled laser control” is activated, then simultaneously with the laser
focus’ motion the signal parameter selected by set_vector_control is linearly varied
from the last valid value to
P
see Section ”Vector-Defined Laser Control”, page 206.
• There is no abs mechanism for
P
.
P
is clipped to the maximum allowed value.
• OUT 618:
For mark vector lengths = 0, no change of signal parameter
P
must be programmed:
– This change is not outputted
– The following [*]para[*] Command (only this one) produces incorrect signal
parameter outputs
• OUT 619:
For mark vector lengths = 0 where a change of signal parameter
P
is programmed, the
following applies:
– These are handled as timed vectors with
T
= 10 µs
– The end value of the signal parameter
P
is outputted
• If para_mark_abs is used along with position-dependent or speed-dependent laser
control for the same control parameter, then the current value of
P
is used as the basis
of the 100% value for laser control (see Section ”Vector-Defined Laser Control”,
page 206).
• [*]para_mark[*] commands generally do not take Sky Writing into account.
