Flexible I/O configuration
Use parameter 0x2631 (PAR 400) to individually adapt the inverter control to the respective
application. This is basically effected by assigning digital control sources ("triggers") to func-
tions of the inverter.
DANGER!
Do not assign a digital input to several functions!
Possible consequence: unforeseeable behaviour of the drive
▶
Ensure that a digital input is always only assigned to one function.
Details
•
Each subcode of 0x2631 (PAR 400) is permanently assigned to a specific function. Functions
are for example "Controller enable", "Quick stop" or "Forward start (CW)".
•
For a function, exactly one (digital) trigger can be set:
Trigger
Function
Digital input 1 Start enable
•
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
0x2631:001
(PAR 400/001)
.
•
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 descriptions
in the following subchapters.
•
If certain assignment guidelines are not complied with (depending on whether the keypad
control or terminal mode has been selected), a corresponding error message is output.
Example: changing the function assignment of a digital input
In order to, for example, cancel the default assignment of digital input 4 to the "Reversal"
function and to assign digital input 4 to the "DC braking" function instead, the following two
settings are required:
