P14.6
PID
contoller
Gain (P) +50 - 50, Gain (proportional value) of the PID controller
P14.7
PID
contoller
Reset time (I) 0 – 100s
The shorter the reset time (integral time, integral
value), the stronger is the effect of the integral
component of the PID controller. Values below 1.0
will disable the integral component.
P14.8
PID
controller
Lead Time
(D)
0 – 100s
The larger the lead time (differential/derivative
value), the stronger is the effect of the dervative
component of the PID controller. To reduce the
influence of noise a first order lag element with
1s time constant is added (DT1) .
P14.9
PID
contoller
Offset -200 – 200% The offset value will be added to the output value
of the PID controller.
P14.10
PID
contoller
Dead Band
0.1 – 10%
{1%}
Tolerance range for the control deviation (setpoint
external actual value) where no adjustment
occurs.
P14.11
PID
contoller
Period 2.– 20 s Equal to parameter P13.10 (see Section 18.12 )
P14.12
PID
controller
Actual Value
Monitoring
Ignore
The monitoring of the external actual value is
disabled.
Stop
Actuator stops on signal failure of external actual
value.
Open
Actuator moves on signal failure of external actual
values to the OPEN position.
Closed
Actuator moves on signal failure of external actual
values to the CLOSED position.
Emergency
position
Actuator moves on signal failure of external actual
values to the EMERGENCY position. (see
parameter P13.7).
