The values given for these tuning parameters are valid under the following conditions:
• The values assume that the minimum configurable PID function block execution period (T
s
) is
0.125 seconds.
• Algorithm typesetting (A, B, or C) has no effect on the validation of these tuning parameters.
The PID function block rejects all values outside the following ranges:
