Mode
set_laser_mode (0) sets the CO
2
Mode
(“Laser Mode 0”).
The timing diagram, see Figure 52, shows the
corresponding signals using the example of an
isolated mark command.
For “laser active” operation:
• The LASERON signal is switched on
• 2 alternating modulation signals are outputted at
the LASER1 and LASER2 output port. Their
pulse length and period duration can be defined
by set_laser_pulses, set_laser_pulses_ctrl or
set_laser_timing.
For “laser standby” operation:
• The LASERON signal is switched off
• Alternating standby pulses are outputted at the
LASER1 and LASER2 output port.
Their pulse length and period duration can be
defined by set_standby or set_standby_list.
