Function symbol
Purpose
PID controller
Parameter
Function inputs
Function output
Description
The change in the output of the PID controller consists of a
proportional, an integral and a differential component. The
variable first changes by an amount (D share) depending on the
change speed of the input variable. After the rate time TV has
elapsed the variable goes back to a value corresponding to the
proportional part and then changes in accordance with the reset
time TN.
The values entered at function inputs KP and KD are internally
divided by 10 to achieve a finer resolution (e.g. KP = 17
corresponds to 1.7)
Variable Y is already normed to the PWM function (RELOAD-
Wert = 65535). Observe the inverse logic (65535 = minimum
value, 0 = maximum value).
If X > XS, the value is increased.
If X < XS, the value is decreased.
