MFI1D Assign to a function, e.g. select signal source for parameter.
7.6.2 Multifunction input MFI2
562 Operation Mode MFI2 (Multifunction input 2)
Multifunction input MFI2 can be configured as a voltage, current or a digital input. In the configuration
as a digital input, the evaluation can be selected as PNP (high-switching) or NPN (low-switching).
Depending on the selected
Operation Mode MFI2 562, various functions of the frequency inverter
can be controlled.
Voltage signal (MFI2A), 0 V … 10 V. Fixed characteristic.
2 -
Current 0…20 mA Current signal (MFI2A), 0 mA … 20 mA. Fixed characteristic.
3 -
Digital NPN (active: 0 V)
Digital signal (MFI2D) 0 V … 24 V. Low-switching (with negative
signal). Factory setting.
4 -
Digital PNP (active: 24 V)
Digital signal (MFI2D) 0 V … 24 V. High-switching (with positive
signal).
5 -
Current 4…20 mA Current signal (MFI2A), 4 mA … 20 mA. Fixed characteristic
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.
By default, multifunction input MFI2 is set as a digital input for connection of a motor thermal contact.
Alternatively, you can select the operation mode for an analog voltage or current signal. The current
signal is continuously monitored and the fault message "F1407" displayed if the maximum figure is
exceeded.
7.6.2.1 Multifunction input set as analog input MFI2A
The Multifunction input can be evaluated either as analogue or digital signal. In the following the
evaluation for analogue signals is described.
7.6.2.1.1 Voltage input and current input
For parameter
Operation Mode MFI2 562, "1 - Voltage 0…10 V", "2 - Current 0…20 mA" or “5 - Cur-
rent 4…20 mA” must be selected.
1 -
Voltage 0…10 V Voltage signal (MFI2A), 0 V … 10 V. Fixed characteristic.
2 -
Current 0…20 mA Current signal (MFI2A), 0 mA … 20 mA. Fixed characteristic.
5 -
Current 4…20 mA Current signal (MFI2A), 4 mA … 20 mA. Fixed characteristic
