Propagation of faults
In the case of faults that are, for example, triggered by the Control Unit or a Terminal
Module, central functions of the drive are also often affected. As a result of propagation,
faults that are triggered by one drive object are therefore transferred to other drive objects.
This response also applies to the faults that are set in a DCC chart on the Control Unit using
a DCC block.
There are the following types of propagation:
● BICO
The fault is propagated to all active drive objects with closed-loop control functions
(infeed, drive) to which there is a BICO interconnection.
● DRIVE
The fault is propagated to all active drive objects with closed-loop control functions.
● GLOBAL
The fault is propagated to all active drive objects.
● LOCAL
The behavior of this propagation type is dependent on parameter p3116.
– With binector input p3116 = 0 (factory setting) the following applies:
The fault is propagated to the first active drive object with closed-loop control
functions.
– With binector input p3116 = 1 signal, the following applies:
The fault is not propagated.
