Parameter Description
NOTE
If a feedback is not used, its source must be set to [0] No
Function. 20-20 Feedback Function determines how the
three possible feedbacks will be used by the PID
Controller.
20-01 Feedback 1 Conversion
Option: Function:
[0] Linear
*
[1] Square This parameter allows a conversion function to
root be applied to Feedback 1.
[0] Linear has no effect on the feedback.
[1] Square root is commonly used when a
pressure sensor is used to provide flow
feedback (
flow ∝ pressure )
(
20-02 Feedback 1 Source Unit
Option: Function:
This parameter determines the unit that is used
for this Feedback Source, before applying the
feedback conversion of 20-01 Feedback 1
Conversion. This unit is not used by the PID
Controller.

NOTE
This parameter is only available when using pressure to

If the choice [0] Linear is selected in 20-01 Feedback 1
Conversion, then the setting of any choice in
20-02 Feedback 1 Source Unit does not matter as conversion
will be one-to-one.
