Parameters
4011
INTERNAL SETPNT
Depends on Units
-
40.0%
and Scale
Sets a constant value used for the process reference.
• Units and scale are defined by parameters 4006 and 4007.
4012
SETPOINT MIN
-500.0%…500.0%
0.1%
0.0%
Sets the minimum value for the reference signal source.
• See parameter 4010.
4013
SETPOINT MAX
-500.0%…500.0%
0.1%
100.0%
Sets the maximum value for the reference signal source.
• See parameter 4010.
4014
FBK SEL
1…13
1
1 (
ACT
1)
Defines the PID controller feedback (actual signal).
• You can define a combination of two actual values (
ACT
1 and
ACT
2) as the feedback signal.
• Use parameter 4016 to define the source for actual value 1 (
ACT
1).
• Use parameter 4017 to define the source for actual value 2 (
ACT
2).
1 =
ACT
1 – Actual value 1 (
ACT
1) provides the feedback signal.
2 =
ACT
1-
ACT
2 –
ACT
1 minus
ACT
2 provides the feedback signal.
3 =
ACT
1+
ACT
2 –
ACT
1 plus
ACT
2 provides the feedback signal.
4 =
ACT
1*
ACT
2 –
ACT
1 times
ACT
2 provides the feedback signal.
5 =
ACT
1/
ACT
2 –
ACT
1 divided by
ACT
2 provides the feedback signal.
6 =
MIN
(
ACT
1,2) – The smaller of
ACT
1 or
ACT
2 provides the feedback signal.
7 =
MAX
(
ACT
1,2) – The greater of
ACT
1 or
ACT
2 provides the feedback signal.
8 = sqrt(
ACT
1-2) – Square root of the value for
ACT
1 minus
ACT
2 provides the feedback signal.
9 = sq
A
1+sq
A
2 – Square root of
ACT
1 plus the square root of
ACT
2 provides the feedback signal.
10 = sqrt(
ACT
1) – Square root of
ACT
1 provides the feedback signal.
11 =
COMM
FBK
1 – Signal 0158
PID
COMM
VALUE
1 provides the feedback signal.
12 =
COMM
FBK
2 – Signal 0159
PID
COMM
VALUE
2 provides the feedback signal.
13 =
AVE
(
ACT
1,2) – The average of
ACT
1 and
ACT
2 provides the feedback signal.
4015
FBK MULTIPLIER
-32.768…32.767 0.001
0.000
(
NOT
SEL
)
Defines an extra multiplier for the PID feedback value FBK defined by parameter 4014.
• Used mainly in applications where the flow is calculated from the pressure difference.
0.000 =
NOT
SEL
– The parameter has no effect (1.000 used as the multiplier).
-32.768…32.767 – Multiplier applied to the signal defined by parameter 4014
FBK
SEL
.
