Cause: A ring-type connection was detected when writing into the target topology.
Fault value (r0949, hexadecimal):
Byte 1: Component number of a component included in the ring
Byte 2: Component class
Byte 3: Connection number
Note:
Component class and connection number are described in F01375.
Remedy: Read-out the fault value and remove one of the specified connections.
Then, download the target topology again using the commissioning software.
201475 <location>Topology: Target topology duplicate connection between two
components
Reaction: NONE
Acknowledge: IMMEDIATELY
Cause: When writing the target topology, a duplicate connection between two components was
detected.
Fault value (r0949, hexadecimal):
Byte 1: Component number of one of the components connected twice
Byte 2: Component class
Byte 3: Connection number 1 of the duplicate connection
Byte 4: Connection number 2 of the duplicate connection
Note:
Component class and connection number are described in F01375.
Remedy: Read-out the fault value and remove one of the two specified connections.
Then, download the target topology again using the commissioning software.
201481 <location>Topology: Comparison, power module missing in the actual
topology
Reaction: NONE
Acknowledge: NONE
Cause: The topology comparison has detected a power module in the target topology that is not
used in the actual topology.
Alarm value (r2124, decimal):
Component number of the additional target components.
Note:
The drive system run-up is stopped. In this state, the drive control (closed-loop) cannot be
enabled.
Remedy: - delete the drive belonging to the power module in the commissioning software project and
download the new configuration into the drive unit.
- check that the actual topology matches the target topology and if required, change over.
- check DRIVE-CLiQ cables for interruption and contact problems.
201482 <location>Topology: Comparison, sensor module missing in the actual
topology
Reaction: NONE
Acknowledge: NONE
Cause: The topology comparison has detected a sensor module in the target topology that is not
used in the actual topology.
Alarm value (r2124, decimal):
Component number of the additional target components.
Note:
The drive system run-up is stopped. In this state, the drive control (closed-loop) cannot be
enabled.
