Propagation of faults
Forwarding faults to the Control Unit
When faults are triggered on the "Control Unit" drive object, it is always assumed that central
functions of the drive are affected. For this reason, these faults are also forwarded to all
other drive objects (propagation). The fault responses act on the Control Unit drive object
and all 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.
A fault propagated from the Control Unit must be acknowledged at all drive objects to which
this fault was transferred. In this way, this fault on the Control Unit is automatically
acknowledged. Alternatively, the faults of the drive objects can also be acknowledged on the
Control Unit.
Alarms are not propagated from the Control Unit, i.e. transferred to other drive objects.
Example
Drive object faults are only transferred to the drives, i.e. a fault on a TB30 stops the drive -
however, a fault on the drive does not stop the TB30.
Forwarding of faults due to BICO interconnections
If two or more drive objects are connected via BICO interconnections, faults of drive objects
of type Control Unit, TB30, DMC20, DME20, all Terminal Modules or ENCODER DO are
transferred to drive objects with closed-loop control functions, e.g. infeed units or Motor
Modules. There is no forwarding of faults within these two groups of drive object types.
This behavior also applies to the faults set in a DCC chart on the above drive object types
with the aid of DCC STM.
