Propagation Of Faults - Siemens SINAMICS G150 Operating Instructions Manual

6.3.5

Propagation of faults

Forwarding faults to the Control Unit
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 forwarded to other drive objects.
This behavior also applies to the faults that are set in a DCC chart on the Control Unit with
the aid of the DCC block.
Propagation types
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:
– With binector input p3116 = 1 signal, the following applies:

The fault is propagated to the first active drive object with closed-loop control
functions.
The fault is not forwarded.
