11/03 Diagnosis / Faults and Alarms
SINAMICS G150
Operating Manual
10-17
Alarm value
(r2124):
Component number of non-assigned component
Remedy: Assign speed sensor and evaluation to a drive.
- Increase the number of sensor data sets (p0140)
- Assign evaluation (p0141)
- Assign speed sensor (p0142)
F1340 –
F1343
Topology: Too many components on one line
Reaction: NONE
Cause: Communication clock cycle of DRIVE-CLiQ ports insufficient for all write transfers.
The reason is that there are too many DRIVE-CLiQ components for the set communication
clock cycle on a line of the CU.
Remedy: - Increase basic clock cycle
- Check DRIVE-CLiQ cabling: The DRIVE-CLiQ ports of the CU should be interconnected to
the same number of components.
Acknowl.: Immediate
F1344 –
F1346
Topology: too many components connected
Reaction: NONE
Cause: Internal buffer overrun for useful data of a DRIVE-CLiQ connection.
Remedy: Check DRIVE-CLiQ connection: The DRIVE-CLiQ ports of the CU should be interconnected
to the same number of components.
Acknowl.: Immediate
F1350 Topology: Unable to read actual topology
Reaction: NONE
Cause: An error has occurred reading the actual topology from r9900 and r9901.
Remedy: Execute a POWER ON
Acknowl.: POWER ON
F1351 Topology: Actual topology Unable to write
Reaction: NONE
Cause: Cannot write actual topology internally in r9900 and r9901. As a result, the actual topology
cannot be read out correctly.
Remedy: Execute a POWER ON
Acknowl.: POWER ON
F1352 Topology: Unable to determine actual topology
Reaction: NONE
Cause: Unable to determine actual topology.
- Insufficient memory.
- Internal access to parameter failed.
- Unknown node identifier for a component
Remedy: - Reduce the number of data sets or drives.
- Perform POWER ON.
Acknowl.: POWER ON
F1355 Topology: Actual topology modified
Reaction: NONE
Cause: The number of components connected via DRIVE-CLiQ (incl. TBxx) is zero or it has been
changed after initial start-up.
This error occurs only if the topology is commissioned via the internal automatic option and
not with the PC tool.
