Special Functions
• Synchronization of scan system and laser control
– Automatic delay adjustments (see
)
– Sky Writing (see
)
• Pixel output mode (scanning bitmaps, see
– Pixel frequencies up to 300 kHz, irrespective of
the 10
µ
s clock
– 15 ns resolution
– 0–100% laser pulse length
– Pixel-Mode 0 not supported
– Reading of analog voltages is not supported
– Pixel marking on sloped surfaces
• Commands for conditional execution of any list
command (see
)
• Possible wobbel motion shapes include not only
circles, but also ellipses, horizontal figure-of-8s,
vertical figure-of-8s, and “freely definable wobbel
shapes”. Options for the orientation of the
wobbel shapes are: stationary in space, continu-
ously and automatically adjusted to the current
direction of motion, or any other freely assigned
motion direction. Unlike “classic” wobbel shapes,
“freely definable wobbel shapes” have an option
to vary the laser power (see
• Processing-on-the-fly (see
– two encoder inputs (RS422) with 32-bit counter
for Processing-on-the-fly correction with
encoder signals on 2 axes (see
); alter-
natively: Processing-on-the-fly correction with
McBSP signals (see
– 24-bit vector coordinates: objects larger than
the image field are possible (virtual processing
field, see
and
– up to 8 objects within the Processing-on-the-fly
track delay (between trigger and marking posi-
tion, see
"External List Start", page 210
– Accurate “external list start”:
If accordingly configured via
, the encoder counter can
be reset via external start signals for synchro-
nizing a Processing-on-the-fly process. The
reset occurs fully simultaneously (without 10
µ
s
jitter) with the external start signal.
– Compensation of 2D motions (XY table)
• Enhanced signal recording (see
).
