Variable
List Command
laser_on_list
Function turns on the “laser active” laser control signals for a specified time interval.
Call
laser_on_list( Period )
Parameter Period time interval in bits as an unsigned 32-bit value.
1bit equals 10µs. Allowed range: 0 
Period  (2
31
–1)
Comments • As of Version OUT 531, bit #31 of
Period is ignored (also see comments and version
info at laser_on_pulses_list).
• The laser control signals for “laser active” operation must first be selected with
set_laser_mode, defined via further commands, and enabled via set_laser_control or
enable_laser before they can be switched on with laser_on_list (see page 128).
• While the laser control signals are turned on, the set position of the scanners is not
changed. The next list command will be executed when the programmed time interval
has passed.
• The currently set LaserOn delay is applied at the beginning of the programmed time
interval: The laser control signals turn on after a LaserOn delay.
– As with other mark commands (e.g. mark_abs), the laser control signals will not
explicitly turn off at the end of the time interval, but instead will only turn off with
a subsequent list command (e.g. jump_abs or list_nop). The currently set LaserOff
delay is applied.
• The command is useful for marking separate points (see page 96).
• Wobbel Mode (see page 167) will be retained, but will be ignored.
•For
Period = 0 the laser control signals won’t turn on; then the laser_on_list command
is a short list command.
