7 Basic Functions for Scan Head Control and Laser Control

Lamp Current (Laser Power)
To control the lamp current of a YAG laser, the 12-bit
analog output ports, ANALOG OUT1 or
ANALOG OUT2 can be used. They are available at the
LASER Connector, see Figure 17. ANALOG OUT2 is
also available at the MARKING ON THE FLY
socket connector, see Figure 25.
To define the analog output signal, the control
command write_da_x and the delayed short
list command write_da_x_list are provided.
Alternatively, the lamp current can be controlled
digitally via the 8-bit digital output port (at the
EXTENSION 2 socket connector, see Figure 24), see
also Section ”8-Bit Digital Output Port”, page 81.
The commands for setting the 8-bit output port are
write_8bit_port, write_8bit_port_list or
write_port_list.
When the lamp current is changed, list execution can
be halted by long_delay until a constant laser power
has been achieved.
