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 set the switch belonging to 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

Advanced commissioning
Changing the function of an analog input:
1. Define the analog input type using
parameter p0756[x] and the switch on the
inverter.
2. You define the analog input function by
interconnecting parameter p0755[x] with
a connector input CI of your choice.
