20-20 Feedback Function
Option: Function:
This parameter determines how the 3 possible
feedbacks are used to control the output
frequency of the adjustable frequency drive.
[0] Sum Sets up the PID controller to use the sum of
feedback 1, feedback 2 and feedback 3 as the
feedback.
NOTICE!
Set any unused feedbacks to [0] No
Function in parameter 20-00 Feedback 1
Source, parameter 20-03 Feedback 2
Source, or parameter 20-06 Feedback 3
Source.
The sum of setpoint 1 and any other references
that are enabled (see parameter group 3-1*
References) are used as the PID controller’s
setpoint reference.
20-20 Feedback Function
Option: Function:
[1] Dierence Sets up the PID controller to use the dierence
between feedback 1 and feedback 2 as the
feedback. Feedback 3 is not used with this
selection. Only setpoint 1 is used. The sum of
setpoint 1 and any other references that are
enabled (see parameter group 3-1* References) are
used as the PID controllers setpoint reference.
[2] Average Sets up the PID Controller to use the average of
feedback 1, feedback 2 and feedback 3 as the
feedback.
NOTICE!
Set any unused feedbacks to [0] No
Function in parameter 20-00 Feedback 1
Source, parameter 20-03 Feedback 2
Source, or parameter 20-06 Feedback 3
Source. The sum of setpoint 1 and any
other references that are enabled (see
parameter group 3-1* References) are used
as the PID controllers setpoint reference.
[3]
*
Minimum Sets up the PID controller to compare feedback
1, feedback 2 and feedback 3 and uses the
lowest value as the feedback.
NOTICE!
Set any unused feedbacks to [0] No
Function in parameter 20-00 Feedback 1
Source, parameter 20-03 Feedback 2
Source, or parameter 20-06 Feedback 3
Source. Only setpoint 1 is used. The sum
of setpoint 1 and any other references
that are enabled (see parameter group
3-1* References) are used as the PID
controller’s setpoint reference.
[4] Maximum Sets up the PID controller to compare feedback
1, feedback 2 and feedback 3 and use the
highest value as the feedback.
NOTICE!
Set any unused feedbacks to [0] No
Function in parameter 20-00 Feedback 1
Source, parameter 20-03 Feedback 2
Source, or parameter 20-06 Feedback 3
Source.
Only setpoint 1 is used. The sum of setpoint 1
and any other references that are enabled (see
parameter group 3-1* References) are used as the
PID controllers setpoint reference.
