The dynamics of the PID controller will depend on the value set in this parameter. Please see also par. 20-93
Proportional Gain.
Par. 20-13 and par. 20-14 also determine the feedback range when using feedback for display readout with
par. 1-00 Configuration Mode

BAS-SVX19C-EN
Function:
Enter the desired minimum value for the remote reference when oper-
ating with par. 1-00
tion. Units are set in par. 20-12
Minimum feedback will be -200% of either the value set in
par. 20-13 Minimum Reference/Feedb.
ence/Feedb., which ever numeric value is the highest.
Configuration Mode set for Open Loop [0], par. 3-02
Function:
Enter the maximum reference/feedback for closed loop operation. The
setting determines the highest value obtainable by summing all refer-
ence sources for closed loop operation. The setting determines 100%
feedback in open and closed loop (total feedback range: -200% to +200%).
Configuration Mode set for Open Loop [0], par. 3-03
set for Open Loop [0]. Same condition as above.
Function:
This parameter determines how the three possible feedbacks will be
used to control the output frequency of the frequency converter.
Sum [0] sets up the PID Controller to use the sum of Feedback 1, Feed-
back 2 and Feedback 3 as the feedback.
Any unused feedbacks must be set to
1 Source, par. 20-03
The sum of Setpoint 1 and any other references that are enabled (see
par. group 3-1*) will be used as the PID Controller's set-point reference.
Difference
[1] sets up the PID controller to use the difference between
Feedback 1 and Feedback 2 as the feedback. Feedback 3 will not be used
with this selection. Only Setpoint 1 will be used. The sum of Setpoint 1
and any other references that are enabled (see par. group 3-1*) will be
used as the PID controller's set-point reference.
Average
[2] sets up the PID Controller to use the average of Feedback 1,
Feedback 2 and Feedback 3 as the feedback.
