Laser power control

Programming example
Polynomial definition using variables
One of the possible applications of polynomial
definition is the laser output control.
Laser output control means:
Influencing the analog output in dependence on, for
example, the path velocity.
$AC_FCTLL[1]=0.2
$AC_FCTUL[1]=0.5
$AC_FCT0[1]=0.35
$AC_FCT1[1]=1.5EX-5
