NOTICE!
Values for setting the minimum reference are found in
open-loop
parameter 3-02 Minimum Reference and for
closed-loop parameter 20-13 Minimum Reference/Feedb. -
values for maximum reference for open-loop are found
in
parameter 3-03 Maximum Reference and for closed-
loop parameter 20-14 Maximum Reference/Feedb. .
6-51 Terminal 42 Output Min Scale
Range: Function:
0 %
*
[0 - 200
%] Scale for the minimum output (0 or 4 mA) of
the analog signal at terminal 42.
Set the value to be the percentage of the full
range of the variable selected in
parameter 6-50 Terminal 42 Output .
6-52 Terminal 42 Output Max Scale
Range: Function:

[0 - 200 %]
20 mA/desired maximum current × 100 %
