Changing the function of individual terminals

In the parameter list, the abbreviation CI, CO, BI or BO as prefix indicates as to whether the
parameter is available as signal for the function of the terminal.
Defining the function of a digital input
Procedure
To define the function of a digital input, proceed as follows:
1. Select the function marked using a BI parameter.
2. Enter the parameter number of the required digital input 722.x into the BI parameter.
You have defined the digital input function.

Advanced settings
When switching over the master control of the inverter (for example, if you select default
setting 7), you must select the correct index of the parameter:
● Index 0 (e.g., P840[00]) applies for the interface assignment on the left side of the macro
illustration.
● Index 1 (e.g., P840[01]) applies for the interface assignment on the right side of the
macro illustration.

Example: p0840[00] = 722.2 → switch on the motor using DI 2

The function of the terminal is defined through a
signal interconnection in the inverter:
• The inverter writes every input signal into a
readable parameter. Parameter r0755 makes the
signal of the analog input available, for example.
To define the function of the input, the
appropriate parameter (connector CI or BI) must
be set to the parameter number of the input.
• Every inverter output is represented by a
parameter that can be written to. The value of
parameter p0771 defines the analog output
signal, for example.
To define the output function, you must set the
parameter number of the output to the parameter
number of the matching signal (binector CO or
BO).
