Initializing the Scan System Control

(1) Use load_correction_file
necessary correction file(s) to the
RTC6 PCIe Board (you can load a correction table
load_program_file
before or after
should load it before select_cor_table; you
should at least load a 1:1 correction table).
See Chapter 8.5 "Controlling 2D Scan Systems
and 3D Scan Systems", page
about using several different correction tables.
(2) Assign the previously loaded correction table(s)
to the scan head control port(s) by
(1)
select_cor_table . This causes the intended
Image Field correction to also be applied to the
default position (0|0) previously set by
load_program_file (in some circumstances,
Image Field correction can even shift the null
position).
After load_program_file, the default assignment
is:
– The first scan head control port uses
correction table #1.
– The second scan head control port is off.
The desired Image Field
active only after a subsequent select_cor_table,
select_cor_table_list,
Mark Command.
(3) Define the scanner delay mode by
set_delay_mode (among others, "Variable
Polygon Delay" or constant
(2)
(4) If necessary , load a table for the "Variable
Polygon Delay" by load_varpolydelay.
The remaining settings (Scanner
and mark speed) are set by further control
commands or list commands.
(1) load_correction_file automatically calls
select_cor_table
with the last assigned table numbers
after loading the correction table (if
load_correction_file follows after
load_program_file), see
(2) Step 4 can be omitted, if a new
by create_dat_file after loading the table. Then, this
table is automatically loaded with the next
load_program_file.

Initializing the Laser Control

(1) Set the laser mode by set_laser_mode.
(2) Set the polarity of the
appropriate to your laser system by
set_laser_control.
(3) Set the FirstPulseKiller length (only for
YAG modes) by set_firstpulse_killer.
(4) Set the delay of the Q-Switch signal (only for
YAG modes, in particular for YAG Mode 5) by
set_qswitch_delay.
(5) Set the stand-by pulses by
particular for Laser Mode 4
(6) Enable the Laser Control Signals
enable_laser), if they have been suppressed by
set_laser_control.
The remaining settings (such as laser timing or
Laser Delays) are set by further control commands or
list commands, for example, see
"Example Code (C)", page 142
"Laser Active" Operation", page

Loading and Executing Lists

(1) Load the list(s).
(2) If necessary, enable the external start input by
set_control_mode.
Notice!
• Carefully check your user program before
running it. Programming errors can cause a
break down of the system. In this case, neither
the laser nor the scan head can be controlled.
