List Command
para_mark_abs
Function
moves the laser focus at marking speed along a 2D vector from the current position to the
specified position (absolute coordinate values) within a two-dimensional image field and,
simultaneously as well as linearly, changes the signal parameter selected via
to the specified value.
Call
para_mark_abs( X, Y, P )
Parameters
X, Y
absolute coordinates of the mark vector end point in
bits
as signed 32-bit
values; allowed range: [–8388608 … 8388607] (out-of-range values will be
edge-clipped). The complete value range [–8388608 … 8388607] is only
usable as a virtual image field e.g. for (enabled) Processing-on-the-fly
applications. The current coordinates will be clipped to [–524288 … 524287]
(real image field size) during runtime directly prior to use of the correction
table.
P
End value of the signal parameter as an unsigned 32-bit value; allowed range:
dependent on the selection made via
Ctrl
parameter),
identical with
(
Value
parameter)
Comments
• If vector-defined laser control has not been previously activated via
then
para_mark_abs
will behave like
(see comments there). The parameter
P
will then be ignored.
• If vector-defined laser control is activated, then simultaneously with the laser focus’
motion (Sky writing isn’t taken into account here) the signal parameter selected via
will be linearly varied from the last valid value to
P
Defined Laser Control", page 147
).
• There is no abs mechanism for
P
.
P
will, if necessary, be clipped to the maximum allowed
value.
• If
para_mark_abs
is used along with position- and/or speed-dependent laser control
for the same control parameter, then the current value of
P
will be used as the basis of
the 100% value for laser control (see
"Vector-Defined Laser Control", page 147
).

5 new command
In RTC
®
4 compatibility mode, the RTC
®
5 multiplies the specified coordinate values by 16
(the permissible range of values is correspondingly reduced).
The parameter
P
does not have a RTC
®
4 compatibility mode. The original RTC
®
5 units
must be used.
