5.3.5  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. 
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 
the drive object of the CU. Alternatively all faults of all drive objects can also be 
acknowledged on the CU. 
If a set alarm is reset on the drive object of the CU, this alarm also disappears automatically 
on the other drive objects to which this alarm was forwarded. 
Forwarding of faults and alarms due to BICO interconnections 
If two or more drive objects are connected via BICO interconnections, faults and alarms of 
CU-type drive objects are forwarded to SERVO-type drive objects.
