• The INTERNAL-BUSY list execution status is set while the jump to the corrected
galvanometer scanner position is executed.
• If the values for parameters
HeadA
or
HeadB
are invalid (values >
number_of_correction_tables) or 0, then select_cor_table turns off the
corresponding scan head signals. The galvanometer scanners then remain in their last
position.
• If the Option “Second Scan Head Control” is not enabled, select_cor_table does not
assign a correction table to the second scan head connector.
• The default setting (after load_program_file) is
(1,0)
, that is, correction table #1 is
used for scan head A, whereas the output signals for scan head B are turned off (this
corresponds to parameter values
HeadA
= 1 and
HeadB
= 0). Initially however, after
load_program_file and until select_cor_table is called or the galvanometer scanners
are explicitly moved, the galvanometer scanners stay in the position (0|0), even if the
correction table content is different.
• If the Option “Second Scan Head Control” is not enabled, then signals of the second
scan head remain permanently turned off; even so, multiple correction tables can still
be loaded and used at any time by the first scan head. Even with one scan head, you
can thereby quickly switch back and forth between several correction tables, for
example, one for a pointer laser and one for the main laser with a different
wavelength, see also Chapter 8.5 ”Controlling 2D Scan Systems and
3D Scan Systems”, page 236.
• In a double scan head system, table #1 is typically used for scan head A,
and table #2 is used for scan head B:
select_cor_table(1,2)
. But you can make a
different assignment at any time.
• For 3D systems, the Option “3D” must be enabled. Provided the RTC6’s Option “3D” is
enabled, you can load several (2D or 3D) correction tables. If the is not enabled, then
the xy axis must be connected to the first scan head connector, the z axis to the x or
y channel of the second scan head connector. If a 3D correction table is assigned to the
first scan head connector, corrected signals for an xy scan head are then transmitted
by the first scan head connector and corrected signals for the z axis are transmitted by
both channels of the second scan head connector. If multiple RTC6 boards with
enabled Option “3D” are installed in a PC, then that many 3-axis systems can be
simultaneously controlled.
