PID Coefficients
This tab appears as follows:
This tab sets values that effect the algorithm used by the PID controller. This tab
allows you to set that following configuration properties:
P The proportional term of the PID controller. Its units
are percent output per process variable unit as specified
on the PID tab. For example, if the process variable
units are degrees C, then the units of this property are
percent output/degree C.
I The integral term of the PID controller. A larger value
results in a smaller action (output change per scan). Its
units are seconds. Enter 0 to disable this coefficient.
D The derivative term of the PID controller. A larger
value results in a larger action. Its units are seconds.
Enter 0 to disable this coefficient.
