3.13.1 20-0* Feedback
20-00 Feedback 1 Source
Up to 3 dierent feedback signals can be used to provide the
feedback signal for the frequency converter’s PID controller.
This parameter denes which input is used as the source of the
rst feedback signal.
Analog input X30/11 and analog input X30/12 refer to inputs on
the optional General Purpose I/O board.
Option: Function:
[0] * No function
[1] Analog Input

[101] Bus Feedback
2
NOTICE
If feedback is not used, set its source to [0] No Function.
Parameter 20-20 Feedback Function determines how the
PID controller uses the 3 possible feedbacks.
20-01 Feedback 1 Conversion
This parameter allows a conversion to be applied to feedback.
Option: Function:
[0] * Linear
[1] Square root
20-03 Feedback 2 Source
The eective feedback signal is made up of up to 3 dierent
input signals. Select which drive input should be treated as the
source of the second of these signals.
Option: Function:
[0] * No function
[1] Analog Input

20-04 Feedback 2 Conversion
Select a conversion for the feedback 2 signal. Select Linear to
leave the feedback signal unchanged.
Option: Function:
[0] * Linear
[1] Square root
3.13.2 20-2* Feedback/Setpoint
20-20 Feedback Function
Select how the feedback should be calculated. The feedback can
be either a single feedback source or a combination of several
feedbacks.
Option: Function:
[0] Sum
[1] Dierence
[2] Average
[3] * Minimum
[4] Maximum
3.13.3 20-8* PI Basic Settings
20-81 PI Normal/ Inverse Control
Select either [0] Normal or [1] Inverse to control the output speed
when the process error is positive.
Option: Function:
[0] * Normal Set the process control to increase
the output speed when the process
error is positive.
[1] Inverse Reduce the output speed when the
process error is positive.
