Function:
Function:
[ 0 - 4999 Enter the minimum reference. The
Reference minimum reference is the lowest value
Feedback obtainable by summing all references.
Unit] The minimum reference is active only
when parameter 3-00 Reference Range is
set to [0] Min.–Max.
The minimum reference unit matches:
•
The option in
parameter 1-00 Configuration
Mode.
•
The unit selected in
parameter 3-01 Reference/
Feedback Unit.
Function:
[-4999.0 - 4999 Enter the maximum reference. The
ReferenceFeed- maximum reference is the highest
backUnit] value obtainable by summing all
references.
The maximum reference unit
matches:
•
The option selected in
parameter 1-00 Configuration
Mode.
•
The unit selected in
parameter 3-00 Reference
Range.
Function:
Sum both external and preset reference
sources.
Use either the preset or the external
reference source. Shift between external and
preset via a command or a digital input.
