Vector-Defined Laser Control
The “vector-controlled laser control”
allows a a signal parameter to be varied linearly along
a mark vector or jump vector.
To initialize the ““vector-controlled laser control””,
set_vector_control must be used to specify which
signal parameter is to be varied with which initial
value (parameters Ctrl and Value ).
Then the signal parameter is varied linearly along a
parameterized mark or jump vector. The end value is
automatically the start value for a subsequent
[*]para[*] Command.
Notes
• List commands for explicitly changing the signal
parameter output value are temporarily effective
or not at all.
• [*]para[*] Commands always use the end value of
the previous [*]para[*] Command as their start
value.
Control commands that write to the same
output port should be avoided while processing a
list of [*]para[*] Commands.
• If the same output port is selected via
set_auto_laser_control for Ctrl , the control
parameter from the [*]para[*] Commands acts as
100% value for the laser control.
Special care should be taken with
set_vector_control ( Ctrl = 7) (Defocus): The
setting of the signal value is always done
immediately. This can lead to Hard Jumps on the
varioSCAN.
• During execution of [*]para[*] Commands, the
Sky Writing mode, see Chapter 7.2.4
”Sky Writing”, page 160, is not taken into
account (but also not deactivated).
