Example of a polynomial for straight section
With upper limit 1000, lower limit -1000, ordinate section
the polynomial is:
FCTDEF(1, -1000,1000,$AA_IM[X],1)
Example of laser output control
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.
