P14.9
PID-contoller
Offset
-200 – 200%
The offset value will be added to the output value of
the PID controller.
P14.12
PID-contoller
Live zero
detect.
0: Ignore
The monitoring of the external actual value
is disabled.
1: Stop
Actuator stops on signal failure of external,
actual value
2: Open
On signal failure of external actual values, actuator
moves to the OPEN position.
3: Closed
On signal failure of external actual values, actuator
moves to the CLOSED position.
4: Emergency
Position
On signal failure of external actual values, actuator
moves to the EMERGENCY position
(see param P13.7).
5: Emergency
PID
Reserved for future use
P14.13
PID-contoller
Calibration of
ext. actual
value
-10.0 -
+10.0%
Calibration process: By applying 20mA to the
external actual value input, this parameter is
corrected until the readout matches 20 mA.
P14.14
PID-contoller
Process
begin
32768 -
+32767
Mantissa of the real process variable
(begin of external actual value)
P14.15
PID-contoller
Process
end
32768 -
+32767
Mantissa of the real process variable (end of
external actual value)
P14.16
PID-contoller
Process
comma shift
-3 - +3
Position of the comma for process begin/end
(P14.14, P14.15), e.g.: mantissa = 200, comma
shift = -2/2, process value = 2.00/20000
P14.17
PID-contoller
Process unit
-
Unit of the real process variable
P14.18
PID-contoller
Dead band
0.1 - 10.0%
{1.0%}
Tolerance range for the control deviation (set point
– external actual value) where no adjustment
occurs.
