Laser power analog signal output. For glass tube laser power
supply, it is recommended to use this pin for power signal.
Please select the correct laser type in the factory parameter settings.
When a glass laser tube is used, and the control signal cable is very long
from the controller to the laser power, if L-AN is for the power control, the
long cable will cause interference and make the laser power unstable. So
for this situation, PWM signal can replace the L-AN to control the glass
tube’s power. And decrease the interference.
