poss. setting Notes / comments
1: Position
The output of the PID controller corresponds to the
position setpoint of the actuator. The positioning
(tracking of the actual position to the setpoint) is
done by the positioner (see 7.12).
2: Speed
The output of the PID controller corresponds to the
change of the position setpoint (speed) of the
actuator. The positioning (tracking of the actual
position to the setpoint) is done by the positioner
(see 7.12).

P14.2
PID-
controller
External
Setpoint
0: fixed
The PID controller uses an internal, fixed setpoint
(see param P14.3).
1: external
The PID controller uses the external setpoint. The
adjustment of this setpoint is done with the params
P13.2 and P13.3 (see 7.12).
P14.3
PID-
controller
Fixed setpoint 0 – 100% Specification of the internal fixed setpoint
P14.4
PID-
controller
Start (at 0%) 0 – 20.5 mA mA value at 0% of the external actual value
P14.5
PID-
controller
End (at
100%)
0 – 20.5 mA mA value at 100% of the external actual value
P14.6
PID-
controller
Gain (P) +50.0 - 50.0 Gain (proportional value) of the PID-controller
P14.7
PID-
controller
Reset time (I) 0 – 100.0 s
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 – 100.0 s
The larger the lead time (differential/derivative
value), the stronger is the effect of the derivative
component of the PID-controller. To reduce the
influence of noise, a first-order lag element with
1sec time constant is added (DT
1
) .
P14.9
PID-
controller
Offset -200 – 200%
The offset value will be added to the output value of
the PID controller.
P14.10
PID-
controller
Dead band
0.1 – 10.0%
{1,0%}
Tolerance range for the control deviation (set point
– external actual value) where no adjustment
occurs.
5)
P14.11
PID-
controller
Period 2.0 – 20.0 s Equal to param P13.10 (see section 7.12)
6)
P14.12
PID-
controller
Min. pulse
time
0.1 – 20.0 s Equal to param P13.9 (see section 7.12)
7)
P14.13
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.
