Synchronized function (SYNFCT)

Function
SYNFCT calculates the output value of a polynomial 3 grade weighted using the input
variables. The result is in the output variables and has maximum and minimum limits.
The evaluation function is used
● in AC control (adaptive control),
● in laser output control,
● with position feed-forward
Syntax
SYNFCT (Polynomial_No., main run variable output, main run variable
input)
Significance
For the output variable, it is possible to select variables that
● with additive influencing
● with multiplicative influencing
● as a position offset or
● directly
affect the machining process.
