17.1.68 L_Curve_2
Alternatively, this FB represents a characteristic curve or cam function y=f(x), whereby the input
signal of the X-axis and the output signal of the Y-axis correspond.
A limitation of the input value can be set in C01026/1
(upper limit) and C01026/2 (lower limit).
The output value is internally limited to ±199.99 %. If a limitation of the output value is active,
bLimit is set to TRUE.
