Parameter Setting value / Description / Note
Parameter
set
Available with option
P412 Process controller setpoint P Always visible
0.0 ... 10.0 V
[ 5.0 ] Fixed specification of a setpoint for the process controller that will only occasionally be altered.
Only with P400 = 14 ... 16 (process controller). Further details can be found in Chap. 10.2
P413 PID control P-component P Always visible
0 ... 400.0 %
[ 10.0 ] Only effective if the function Actual frequency PID is selected.
The P-component of the PID controller determines the frequency jump if there is a control deviation
based on the control difference.
E.g.: At a setting of P413 = 10% and a rcontrol difference of 50%, 5% is added to the actual
setpoint.
P414 PID control I-component P Always visible
0 ... 300.0 %/ ms
[ 1.0 ] Only effective if the function actual frequency PID is selected.
The I-component of the PID controller determines the frequency change, dependent on time.
P415 PID control D-component P Always visible
0 ... 400.0 %ms
[ 1.0 ] Only effective if the function actual frequency PID is selected.
If there is a rule deviation, the D-component of the PID controller determines the frequency change
multiplied by time (%ms).
If one of the analog inputs is set in the function actual value process controller, this parameter
determines the controller limitation (%) after the PI controller. For further details, see Section 10.2.
P416 Ramp PID controller P Always visible
0 ... 99.99s
[ 2.00 ] Only effective if the function actual frequency PID is selected.
Ramp for PID setpoint
Note: Further details about the PID and process controller can be found in Section 10.2 and 10.3
P417 Offset analog output 1 P
STD MLT
-10.0 ... +10.0 V
[ 0.0 ] In the analog output function an offset can be entered to simplify the processing of the analog signal
in other equipment.
If the analog output has been programmed with a digital function, then the difference between the
switch-on point and the switch-off point can be set in this parameter (hysteresis).
