6.3 Fault and alarm messages
Once an external fault (1 to 3) has been triggered on the Control Unit drive object, this fault is
also present on all associated drive objects. If one of these external faults is triggered on a
different drive object, it is only present on that particular drive object.

Note
An external fault or alarm is triggered by a 1/0 signal.
An external fault and alarm do not usually mean that an internal drive message has been
generated. The cause of an external fault and alarm should, therefore, be remedied outside the
drive.
6.3.3

Propagation of faults

Overview
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.
Propagation types
The following types of propagation are available:
• 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.
– For binector input p3116 = 0 signal, the following applies (factory setting):
– For binector input p3116 = 1 signal, the following applies:
340
––> External fault 1
––> External fault 2
––> External fault 3
––> External alarm 1
––> External alarm 2
––> External alarm 3
The fault is propagated to the first active drive object with closed-loop control functions.
The fault is not propagated.
