Hi, I assume you are using standard PID blocks with Step7 classic. Have a look at the Standard PID Control under page 4.42: "In a PI controller, the D action is disabled. (D_SEL = FALSE). A PI controller adjusts the output variable PID_OUTV using the I action until the error signal ER becomes zero. This only applies when the output variable does not exceed the limits of the manipulated value." |
