Diagnosis / Faults and Alarms
Fault value Byte 1: Component number of a component contained in the ring
(r0949): Byte 2: Connection type
Byte 3: Connection type
Note:
The connection type and number are described in F1375.
Remedy: Output the fault value and remove one of the specified connections. Then reload the target
topology using the commissioning software.
Acknowl.: Immediate
F1471
Topology: Target topology: Ring connection with control unit
Reaction: NONE
Cause: Ring connection originating from the control unit detected on writing target topology to p9902
and p9903
Fault value Byte 1: Component number of the component connected to the control unit
(r0949): Byte 2: Connection type
Byte 3: Connection number
Note:
The connection type and number are described in F1375.
Remedy: Output the fault value and remove one of the specified connections. Then reload the target
topology using the commissioning software.
Acknowl.: Immediate
F1475
Topology: Target topology Duplicate connection between two components
Reaction: NONE
Cause: Double connection between 2 components detected on entering the target topology in
p9902 and p9903
Fault value Byte 1: Component number of a double-connected component
(r0949): Byte 2: Connection type
Byte 3: Connection number 1 of double connection
Byte 4: Connection number 2 of double connection
Note:
The connection type and number are described in F1375.
Remedy: Output the fault value and remove the two specified connections. Then reload the target
topology using the commissioning software.
Acknowl.: Immediate
F1505
BICO: Interconnection cannot be set up
Reaction: NONE
Cause: The chosen interconnection cannot be set up.
Fault value Parameter to be modified.
(r0949): Exceptions:
922: Interconnection must not be changed because the current selection of the PROFIBUS
telegram in P0922 requires the present one.
Remedy: Set up another interconnection.
Acknowl.: Immediate
F1511
BICO: Message: BICO Interconnection Between Different Scalings
Reaction: NONE
Cause: Message: The required interconnection has been established, but a conversion is being
carried out between the BICO output and BICO input.
This occurs when the BICO output is scaled differently to the BICO input, or when you
switch between drives whose p2000 ff reference values are different.
The conversion is carried out using the p2000 ff reference values.
Example:
The BICO output is a voltage and the BICO input is a current. Factor p2002/p2001 is
calculated between the BICO output and BICO input.
Fault value Parameter number of the signal sink.
(r0949):
Remedy: No action required
