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
Programming
SYNFCT (Polynomial_No., main run variable output, main run variable
input)
Parameters
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.
