3.5 Parameters: 3-** Reference/Ramps
Parameters for reference handling, definition of limitations,
and configuration of the reaction of the frequency
converter 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

1-00 Configuration Mode .
[0] Min -
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
[1] Speed
closed loop control or [3] Process is selected in
1-00 Configuration Mode .
