Dening the analog input type
The parameter p0756[x] and the switch on the converter specify the analog input type.
AI 0 Unipolar voltage input 0V…+10V p0756[0]= 0
Unipolar voltage input monitored +2V…+10V 1
Unipolar current input 0mA…+20mA 2
Unipolar current input monitored +4mA…+20mA 3
Bipolar voltage input ‑10V…+10V 4
No sensor connected --- 8
In addition, you must also set the switch associated with the analog input. You can nd the
switch on the Control Unit behind the front doors.
• Voltage input: Switch position U (factory setting)
• Current input: Switch position I
Dening the function of an analog input
You dene the analog input function by interconnecting a connector input of your choice
with parameter p0755. Parameter p0755 is assigned to the particular analog input via its
index, e.g. parameter p0755[0] is assigned to analog input0.
Connector inputs are designated in the parameter list with "CI".

In order to enter the supplementary setpoint via analog input AI0, you must interconnect
AI0 with the signal source for the supplementary setpoint.
Set p1075=755[0].
