4010 SET POINT SEL 0…20
Defines the reference signal source for the PID controller.
• Parameter has no significance when the PID regulator is by-passed
(see 8121
REG BYPASS CTRL
).
0 =
KEYPAD
– Control panel provides reference.
1 =
AI
1 – Analogue input 1 provides reference.
2 =
AI
2 – Analogue input 2 provides reference.
8 =
COMM
– Fieldbus provides reference.
9 =
COMM
+
AI
1 – Defines a fieldbus and analogue input 1 (
AI
1)
combination as the reference source. See Analogue input reference
correction on page 282 .
10 =
COMM
*
AI
1 – Defines a fieldbus and analogue input 1 (
AI

combination as the reference source. See Analogue input reference
correction on page 282 .
11 =
DI
3
U
,4
D
(
RNC
) – Digital inputs, acting as a motor potentiometer
control, provide reference.
•
DI
3 increases the speed (the U stands for “up”)
•
DI
4 decreases the reference (the D stands for “down”).
• Parameter 2205
ACCELER TIME
2 controls the reference signal’s rate
of change.
•
R
= Stop command resets the reference to zero.
•
NC
= Reference value is not copied.
12 =

U
,4
D
(
NC
) – Same as
DI
3
U
,4
D
(
RNC
) above, except:
• Stop command does not reset reference to zero. At restart the motor
ramps up, at the selected acceleration rate, to the stored reference.
13 =
DI
5
U
,6
D
(
NC
) – Same as
DI
3
U
,4
D
(
NC
) above, except:
• Uses digital inputs
DI
5 and
DI
6.

reference correction on page 282 .
19 =
INTERNAL
– A constant value set using parameter 4011 provides
reference.
20 =
PID
2
OUT
– Defines PID controller 2 output (parameter 0127
PID
2
OUTPUT
) as the reference source.
