Remedy: Adapting the topologies:
- check the component soft-wired connections against the hardware configuration of the
drive unit in the commissioning software and correct differences.
- parameterize the topology comparison of all components (p9906).
- parameterize the topology comparison of one components (p9907, p9908).
201421 <location>Topology: Comparison, different components
Reaction: NONE
Acknowledge: NONE
Cause: The topology comparison has detected differences in the actual and target topologies in
relation to one component. The component class, the component type or the number of
connections differ.
Alarm value (r2124, hexadecimal):
Byte 1: Component number of the component
Byte 2: Component class of the target topology
Byte 3: Component class of the actual topology
Byte 4 (cause):
1: Different component class
2: Different component type
3: Different order number
4: Different number of connections
Note:
Component class, component type and connection number are described in F01375.
The drive system run-up is stopped. In this state, the drive control (closed-loop) cannot be
enabled.
Remedy: Check the component soft-wired connections against the hardware configuration of the
drive unit in the commissioning software and correct differences.
201425 <location>Topology: Comparison, serial number of a component is
different
Reaction: NONE
Acknowledge: NONE
Cause: The topology comparison has detected differences in the actual and target topologies in
relation to one component. The serial number is different.
Alarm value (r2124, hexadecimal):
Byte 1: Component number of the component
Byte 2: Component class
Byte 3: Number of differences
Note:
The component class is described in F01375.
The drive system run-up is stopped. In this state, the drive control (closed-loop) cannot be
enabled.
Remedy: Adapting the topologies:
- change over the actual topology to match the target topology.
- download the target topology that matches the actual topology (commissioning software).
Re byte 3:
Byte 3 = 1 --> can be acknowledged using p9904 or p9905.
Byte 3 > 1 --> can be acknowledged using p9905 and can be de-activated using p9906 or
p9907/p9908.

201428 <location>Topology: Comparison, connection of a component is
different
Reaction: NONE
Acknowledge: NONE
