Diagnosis
3.3 Fault and alarm messages
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 warning should, therefore, be remedied
outside the drive.

Forwarding of faults and alarms

Forwarding of faults and alarms of the CU
When faults or alarms are triggered on the drive object of the CU, it is always assumed that
central functions of the drive unit are affected. For this reason, these faults and alarms are
not only signaled on the drive object of the CU, but are also forwarded to all other drive
objects. The fault reaction affects the drive object of the CU and all other drive objects. This
behavior also applies to the faults and alarms set in a DCC chart on the CU with the aid of
the DCB STM.
A fault that is set on the drive object of the CU must be acknowledged on all drive objects to
which this fault was forwarded. In this way, the fault is then automatically acknowledged on
