16 Control inputs and outputs

The modular structure of the frequency inverters enables a wide spectrum of applications 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.
16.1

Multifunction input MFI1

Multifunction input MFI1 can be configured as a voltage, current or a digital input. Depending on the
selected
Operation Mode
is possible. The unused operation modes are assigned the signal value 0 (LOW).
Operation Mode 452
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, S2IND, etc. For this reason, this input should only be used for signals which
are not time-critical.
16.1.1

Analog Input MFI1A

Multifunction input MFI1 is configured by default for an analog reference value source with a voltage
signal of 0V to 10V.
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 error signal "F1407" displayed if the maximum
figure is exceeded.

16.1.1.1 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.
