1. Define the analog input type using
parameter p0756 and the switch on the
inverter (e.g. voltage input -10 V … 10 V or
current input 4 mA … 20 mA).
2. Interconnect parameter p0755 with a
connector input of your choice (e.g. as
speed setpoint).
Connector inputs are designated with "CI" in
the parameter list of the List Manual.
Define the analog input type
The inverter offers a series of default settings, which you can select using parameter p0756:
