Interconnecting a digital input via BICO
● Deselect the pre-assignment (corresponding parameter value acc. to the tables above =
0)
● Interconnect the input with the corresponding binector input.
Example: If you wish to open a motor holding brake via a digital input, set p0855.0 = 722.5.
For more information, see the parameter list and in the function block diagrams 2220 ff of the
List Manual. A list of all of the binector inputs is also provided in the List Manual.
