Normal
List Command micro_vector_abs_3d
Function moves the output point (of the laser focus) via a hard jump (without microvectorization)
directly from the current position to the specified position (absolute coordinate values)
within a three-dimensional process volume.
Restriction If the 3D option is not enabled or no 3D correction table has been assigned (see
select_cor_table ), then the command will have the same effect as micro_vector_abs .
Call
micro_vector_abs_3d( X, Y, Z, LasOn, LasOff )
Parameters
X, Y, Z
absolute coordinates of the micro vector end point in bits as signed 32-bit
values; allowed range:
• for
X
and
Y
: [–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 applica-
tions. The current coordinates will be clipped to [–524288 … 524287] (real
image field size) during runtime directly prior to use of the correction table.
• for
Z
: [–32768 … 32767] (out-of-range values will be edge-clipped).
LasOn,
LasOff
LaserOn delay and LaserOff delay as signed 32-bit values.
1 bit equals 0.5 µ s.
Allowed range (as with set_laser_delays ): [ – 2
31
… +(2
15
–
1)]

0: Delay will be newly set (values over (2
15
–1) will be clipped).
< 0: The previously defined delay continues unaffected.
Comments • Except for the additional motion in the third dimension, this command functions simi-
larly to the micro_vector_abs command (see the comments there).
• The X and Y axes can be controlled with 20-bit resolution, the Z axis with 16-bit resolu-
tion. The RTC
®
5 (in RTC
®
5 mode as well as in RTC
®
4 compatibility mode) automatically
upscales Z coordinate values internally to 20-bit values, so that the three dimensions of
space can be handled equivalently in terms of the supplied jump speed value.
• During calculation of the Z output value to the scan system, any previously defined
offset to the Z coordinate and focal length is taken into account (see page 126 ).

RTC

5 new command
In RTC
®
4 compatibility mode, the RTC
®
5 multiplies the specified value for the X and Y
coordinates by 16 and the specified delay values by 2 (the permissible range of values is
correspondingly reduced). The value range for Z coordinates is identical for the RTC
®
5 and
RTC
®
4.
