10.4.8 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.

;in dependence on the path velocity (stored in $AC_VACTW) the
laser output control is controlled via analog output 1
