7.6.2.1.2 Voltage input characteristic and current input characteristic
For parameter
Operation Mode MFI2 562, "6 - Voltage, characteristic" or "7 - Current, characteristic"
must be selected.
6 -
Voltage, characteristic
Voltage signal (MFI2A), 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 (MFI2A) 0 mA … 20 mA. The output signal is in-
fluenced by the set characteristic. The characteristic can be set
via parameters 564 … 567.
564 Characteristic Curve Point X1
565 Characteristic Curve Point Y1
566 Characteristic Curve Point X2
567 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.

The coordinates of the points relate, as a percentage, to the analog signal with 10 V or 20 mA and
parameter
Maximum Frequency 419 or parameter Maximum Reference Percentage 519. The direc-
tion of rotation can be changed via the digital inputs and/or by selection of the points.
WARNING
The monitoring of the analog input signal via the parameter Error/Warning Behaviour
563 demands the check of parameter Characteristic Curve Point X1 564.
