7.3 Analog terminals
The analog input terminals together with the analog output terminals are located on the X3 plug
connector.
Analog input terminals
The drive controller has four analog input terminals for detecting two current signals and two
voltage signals:
• Voltage signals in the ± 10 V range
The voltage signal can be e.g. an analog speed setpoint or the signal of an external sensor
(temperature, pressure, etc.).
• Current signals in the 0/+ 4 ... + 20 mA range
For open-circuit monitoring, the current signal can be evaluated with regard to "Life Zero" or
"Dead Zero":
• 0 ... 20 mA, without open-circuit monitoring
• 4 ... 20 mA, with open-circuit monitoring
Analog output terminals
The drive controller has four analog output terminals.
• Two output terminals output an analog current signal (O1I, O2I)
• Two output terminals output an analog voltage signal (O1U, O2U)

Note!
To avoid undefined states, free input terminals of the controller must be assigned as
well, e.g. by applying 0 V to the terminal.

Note!
Initialisation behaviour:
• After mains switching up to the start of the application, the analog outputs remain
set to 0 V.
Exception handling:
• In case of a critical exception in the application (e.g. reset), the analog outputs are set
to 0 V.
