Scan-System-Error-Induced Laser-Signal
Auto-Suppression
set_laser_control (bits#16 – 27) can be used to
define that the laser control signals shall be automat-
ically suppressed when one or more scan-system
status signals indicate an error. It can also be used to
select, which status signals to be used for this laser-
signal auto-suppression: PowerOK, TempOK and/or
PosAck status signals of heads A and/or B and axes X
and/or Y.
If – in case of an error – at least one of the selected
status signals switches to 0, then
• output of the laser control signals (enabled via
set_laser_control or enable_laser) will be
automatically interrupted and will only be
continued if all selected status signals are simul-
taneously 1 (laser control signals disabled via
set_laser_control, disable_laser
remain disabled regardless of the status signals'
current value),
• internal error bits are (cumulatively) set, which
can be read-out via get_marking_info
version DLL 527, OUT 529).
• if accordingly set via
set_laser_control(bit#28 = 1), a /STOP-Signal is
automatically generated (list will stop, laser
control signals get permanently switched off).
• if accordingly set via
set_laser_control(bit#28 = 1), a /STOP signal is
automatically generated (list will stop, laser
control signals get permanently switched off).
Galvanometer Position Exceedance-Induced
Laser-Signal Auto-Suppression
range_checking can be used to define that the laser
control signals shall be automatically suppressed
when a galvanometer exceeds a given position limit.

7.4.2 Configuring the Laser
To configure the laser signal types to be put out on
pins 1, 2 and 9 at the LASER connector, you can use
the control command
version DLL 535, OUT 535, RBF 524) and the list
command
DLL 537, OUT 537).
If you employ a variety of lasers or laser operational
modes, then these commands might eliminate the
need to configure at the hardware level (i.e. using
various cables and switches).
Whereas the default setting (for normal vector
marking) outputs the LaserOn signal as a laser start
signal on the LASERON channel, you could, for
example, configure the LASER2 signal as a gate signal
outputted on the LASERON channel in pixel mode
or pause_list
with pulse picking.
For other operational modes, you could also, for
example, configure the FirstPulseKiller signal as the
laser start signal on the LASERON channel. This way,
(as of
LASER1 signals can be outputted even before a
delayed switch-on of the laser (which isn't possible in
the default setting, see
config_laser_signals/config_laser_signals_list
command description).
The following description of the various laser modes
applies to the default setting for laser signal output.
