A01421 Topology: Comparison different components
Drive object: All objects
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, interpret 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 is no longer booted. 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 commission-
ing software and correct differences.
Note:
Under "Topology --> Topology view" the commissioning software offers improved diagnostics capability (e.g. set-
point/actual value comparison).
A01425 Topology: Comparison serial number of a component is different
Drive object: All objects
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, interpret 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 is no longer booted. 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.
Note:
Under "Topology --> Topology view" the commissioning software offers improved diagnostics capability (e.g. set-
point/actual value comparison).
