6-51 Terminal 42 Output Min Scale
Range: Function:
0.00 %* [0.00 - 200.00 %] 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 par.6-50

6-52 Terminal 42 Output Max Scale
Range: Function:
100.00 %* [0.00 - 200.00 %] Scale for the maximum output (20 mA) of the analog signal at terminal 42.
Set the value to be the percentage of the full range of the variable selected in par.6-50

.
It is possible to get a value lower than 20 mA at full scale by programming values >100% by using
a formula as follows:
20 mA / desired maximum current × 100 %
i . e . 10 mA :
20 mA
10 mA
× 100 % = 200 %
