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.
P14.12
PID-controller
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
Actuator moves on signal failure of external actual values
to the OPEN position.
3: Close
Actuator moves on signal failure of external actual values
to the CLOSED position.
4: Emergency
position
Actuator moves on signal failure of external actual values
to the EMERGENCY position (see param P13.7)
P14.13
PID-controller
Calibration of
ext. actual
value
-10.0. . . +10.0%
Calibration process: By applying 20 mA to the external
actual value input, this parameter is corrected until the
readout matches to 20 mA.
P14.14
PID-controller
Process begin
-32768. . . +32767
Mantissa of the real process variable (begin of external
actual value).
P14.15
PID-controller
Process end
-32768. . . +32767
Mantissa of the real process variable (end of external
actual value).
P14.16
PID-controller
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-controller
Process unit
–
Unit of the real process variable
P14.18
PID-controller
Dead Band
-0.1. . . 10.0%
Tolerance range for the control deviation (set point -
external actual value) where no adjustment occurs.
