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

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.
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!
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.
