6.2 Analog terminals
The controller is provided with two analog input terminals (O1U and O1I) at the socket X50 for
detecting a current or voltage signal.
• Voltage signal in the 0 ... + 10 V range
The voltage signal can be e.g. an analog speed setpoint selection or the signal of an external
sensor (temperature, pressure, etc.).
• Current signal 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, unassigned inputs of the controller must be assigned as well,
e.g. by applying 0 V to the terminal.
