Parameter
Operation Mode MFI1 452 must be set to "5 - Current 4…20 mA". The coordinates of the
points relate, as a percentage, to the analog signal with 19.6 mA and parameter
Maximum Frequency
419 or parameter Maximum Reference Percentage 519. The zero-crossing of the frequency or the
percentage value lies at 4.4 mA. The deviations from 20 mA and 4 mA allow the operation even with
voltage supplies that have small deviations from the nominal values.

7.6.1.1.2 Voltage input characteristic and current input characteristic
For parameter
Operation Mode MFI1 452, "6 - Voltage, characteristic" or "7 - Current, characteristic"
must be selected.
6 -
Voltage, characteristic
Voltage signal (MFI1A), 0 V ... 10 V. The output signal is influ-
enced by the set characteristic. The characteristic can be set via
7 -
Current, characteristic
Current signal (MFI1A) 0 mA … 20 mA. The output signal is in-
fluenced by the set characteristic. The characteristic can be set
via parameters 454 … 457.

457 Characteristic Curve Point Y2
The analog input signal is mapped to a reference frequency or percentage. Parameterization can be
done via two points of the linear characteristic of the reference value channel.
Point 1 with coordinates X1 and Y1 and point 2 with coordinates X2 and Y2 can be set in four data
sets.
