Function:
Enter the desired minimum
value for the remote
reference when operating
with 1-00 Configuration Mode
set for Closed Loop [3]
operation. Units are set in
20-12 Reference/Feedback
Unit.
Minimum feedback will be
-200% of either the value set
in 20-13 Minimum Reference/
Feedb. or in 20-14 Maximum
Reference/Feedb., which ever
numeric value is the highest.
