Analog inputs

Overview
Connector inputs are marked with "CI" in the parameter list of the List Manual.
Defining the analog input type
The inverter offers a series of default settings, which you can select using parameter p0756:
AI 0
AI 1
In addition, you must also set the switch associated with the analog input. You
can find the switch on the Control Unit behind the lower front door.
● Voltage input: Switch position U (factory setting)
● Current input: Switch position I

The parameter p0756[x] and the switch on the
inverter specify the analog input type.
Define the function of the analog input by inter‐
connecting parameter p0755[x] with a connec‐
tor input CI of your choice.
