Flexible I/O configuration

Use parameter 0x2631 (P400xx) to individually adapt the inverter control to the respective
application. This is basically effected by assigning digital signal sources ("triggers") to functions
of the inverter.
NOTICE
A digital signal source can be assigned to several functions.
Possible consequence: unforeseeable behaviour of the drive in case of incorrect assignment
▶ Carry out assignment of a digital signal source to several functions with greater care.
Details
Each subcode of 0x2631 (P400) is permanently assigned to a specific function. Functions
•
are for example "Enable inverter", "Activate quick stop" or "Start forward (CW)".
For a function, exactly one (digital) trigger can be set:
•
Trigger
Digital input 1
Possible triggers to be selected are for example the digital input and internal status signals
•
of the inverter.
A list of all triggers available can be found in the description for the parameter
•
(P400.01).
If the trigger condition is met, the corresponding function is executed. More details with
•
regard to the respective trigger conditions can be gathered from the functional descrip-
tions in the following subchapters.
Example: changing the function assignment of a digital input
Task for this example:
1. The preset assignment of the digital input 3 for "Reverse rotational direction" function is
to be cancelled.
2. Instead, the digital input 3 is to be assigned to the "Activate DC braking" function.
For this purpose, the following two settings are required:
Function
Default: 0x2631:013
New: 1. 0x2631:013
2. 0x2631:005
