Analog Input Reference Correction
Parameter values 9, 10, and 14…17 use the formula in the following table.
Where:
• C = Main Reference value ( =
COMM
for values 9, 10 and =
AI
1 for values 14…17).
• B = Correcting reference ( =
AI
1 for values 9, 10 and =
AI
2 for values 14…17).
Example:
The figure shows the reference source curves for
value settings 9, 10, and 14…17, where:
• C = 25%.
• P 4012
SETPOINT
MIN
= 0.
• P 4013
SETPOINT
MAX
= 0.
• B varies along the horizontal axis.
4011
INTERNAL SETPNT
-1000.0…1000.0%
0.1%
40.0%
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.

1
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
(
A
1,
A
2) – The smaller of
ACT
1 or
ACT
2 provides the feedback signal.
7 =
MAX
(
A
1,
A
2) – The greater of
ACT
1 or
ACT
2 provides the feedback signal.
8 =
SQRT
(
A
1-
A
2) – Square root of the value for
ACT
1 minus
ACT
2 provides the feedback signal.
9 =
SQA
1 +
SQA
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.

AI reference is calculated as following:
C + B
C value + (B value - 50% of reference value)
C * B
C value * (B value / 50% of reference value)
C - B
(C value + 50% of reference value) - B value
C / B
(C value * 50% of reference value) / B value
