Start-Up
23.3. PID.PARAMETER – Parameterizing the process
controller
The following control parameters of the process controller are manually set in this menu.
DBND 1.0 % Insensitivity range (dead band) of the process controller
KP 1.00 Amplification factor of the (P-contribution of the PID controller)
TN 999.0 Reset time (I-contribution of the PID controller)
TV 0.0 Hold-back time (D-contribution of the PID controller)
X0 0.0 % Operating point
FILTER 0 Filtering of the process actual value input
The automatic parameterization of the PID controller integrated in the process controller
(menu options KP, TN. TV) can be implemented with the aid of the P.TUNE function
(see Chapter "23.5. P.TUNE – Self-optimization of the process controller").
Basic information for setting the process controller can be found in Chapters "35. Properties of PID Con-
trollers" and "36. Adjustment rules for PID Controllers".
