3.5 Parameters: 3-** Reference / Ramps
Parameters for reference handling, defining limitations and
configuring the reaction of the adjustable frequency drive to
changes.
3.5.1 3-0* Reference Limits
3-00 Reference Range
Option: Function:
Select the range of the reference signal and the
feedback signal. Signal values can be positive only,
or positive and negative. The minimum limit may
have a negative value, unless Speed closed-loop [1]
control or Process [3] is selected in 1-00 Configu-
ration Mode .
[0] Min to
Max
Select the range of the reference signal and the
feedback signal. Signal values can be positive only,
or positive and negative. The minimum limit may
have a negative value, unless Speed closed-loop [1]
control or Process [3] is selected in 1-00 Configu-
ration Mode .
[1]

-Max to
+Max
For both positive and negative values (both
directions, relative to 4-10 Motor Speed Direction ).
3-01 Reference/Feedback Unit
Option: Function:
Select the unit to be used in process PID
control references and feedback. 1-00 Configu-
ration Mode must be either [3] Process or [8]
Extended PID Control.

3-02 Minimum Reference
Range: Function:

[Application
dependant]
Enter the minimum reference. The
minimum reference is the lowest
value obtainable by summing all
references.
Minimum Reference is active only
when 3-00 Reference Range is set to
Min.- Max. [0].
The minimum reference unit matches:
•
The choice of configuration
in 1-00 Configuration Mode
Configuration Mode : for
Speed closed-loop [1], RPM;
for Torque [2], Nm.
•
The unit selected in
3-01 Reference/Feedback
Unit .
