6.1.1 Flexible I/O conguraon
Use parameters 0x2631:xx (P400.xx) to individually adapt the inverter control to the respec-
ve applicaon. This is basically eected by assigning digital control sources ("triggers") to
funcons of the inverter.
NOTICE
A digital signal source can be assigned to several funcons.
Possible consequence: unforeseeable behaviour of the drive in case of incorrect assignment
▶
Carry out assignment of a digital signal source to several funcons with greater care.
Details
•
The exible I/O conguraon is acve if the selecon "Flexible I/O conguraon [0]"
(default) is set in 0x2824 (P200.00).
•
Each subcode of 0x2631 (P400) is permanently assigned to a specic funcon. Funcons
are for example "Enable inverter", "Acvate quick stop" or "Start forward (CW)".
•
For a funcon, exactly one (digital) trigger can be set:
Trigger Function
Digital input 1 Run
•
Possible triggers to be selected are for example the digital input and internal status signals
of the inverter.
•
A list of all available triggers can be found in the "Trigger list". ^ 64
•
The corresponding funcon is executed if the trigger condion is fullled.
Example: changing the funcon assignment of a digital input
Task for this example:
1.
The preset assignment of the digital input 3 for the funcon "Reverse rotaonal direcon"
is to be cancelled.
2.
Instead, the digital input 3 is to be assigned to the "Acvate DC braking" funcon.
For this purpose, the following two sengs are required:
