15 Control Inputs and Outputs

The modular structure of the frequency inverters enables a wide spectrum of appli-
cations on the basis of the available hardware and software functionality. The control
inputs and outputs of terminals X210A and X210B described in the following can be
linked to software modules freely via the described parameters.
15.1

Multi-Function Input MFI1

Multifunction input MFI1 can be configured as a voltage, a current or a digital input.
Depending on the selected
various functions of the software is possible. The unused operation modes are as-
signed the signal value 0 (LOW).
Operation mode
1 - Voltage Input
2 - Current Input
3 - Digital Input
The sampling rate of multi-function input MFI1D is slower than that of digital signals
S1IND/STOA, S2IND, etc. For this reason, this input should only be used for signals
which are not time-critical.

15.1.1 Analog input MFI1A

Multifunction input MFI1 is configured by default for an analog reference value source
with a voltage signal of 0 V to 10 V.
Alternatively, you can select the operation mode for an analog current signal of 0 mA
to 20 mA. The current signal is continuously monitored and the fault message
"F1407" displayed if the maximum figure is exceeded.

15.1.1.1 Characteristic

Mapping of the analog input signal onto a reference frequency value or a reference
percentage value is possible for various requirements. 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.
No.
454 Point X1
455 Point Y1
456 Point X2
457 Point Y2
The coordinates of the points relate, as a percentage, to the analog signal with 10 V
or 20 mA and parameter
age reference
and/or by selection of the points.
WARNING
The monitoring of the analog input signal via the parameter
453 demands the examination of the parameter
