Overview of Alarms
Cause: The topology comparison has detected a motor with DRIVE-CLiQ in the actual topology
that has been shifted with respect to the target topology.
Alarm value (r2124, hexadecimal):
Byte 1: Component number of the component shifted in the target topology
The connection in the actual topology where the shifted component was detected, is
described in bytes 2, 3 and 4.
Byte 2: Component class
Byte 3: Component number
Byte 4: Connection number
Note:
Component class 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: Adapting the topologies:
- undo the change to the actual topology by changing-over the DRIVE-CLiQ cables.
- commissioning software: Go online, upload the drive unit, adapt the topology offline and
download the modified project.
- automatically remove the topology error (p9904).
201416 <location>Topology: Comparison, additional component in actual
topology
Reaction: NONE
Acknowledge: NONE
Cause: The topology comparison has found a component in the actual topology which is not
specified in the target topology. The alarm value defines the connection at which the
additional component was detected.
Alarm value (r2124, hexadecimal):
Byte 1: Component number
Byte 2: Component class
Byte 3: Connection number
Note:
Component class and connection number are described in F01375.
Remedy: Adapting the topologies:
- remove the additional component in the actual topology.
- download the target topology that matches the actual topology (commissioning software).
201420 <location>Topology: Comparison, 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. There are differences in the electronic rating plate.
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 type
2: Different order number
3: Different manufacturer
4: Connection changed-over for a multi-component slave (e.g. double motor module) or
defective EEPROM data in the electronic rating plate
5: A CX32 was replaced by an NX10 or NX15.
6: An NX10 or NX15 was replaced by a CX32.
Note:
Component class and component type are described in F01375.
The drive system run-up is stopped. In this state, the drive control (closed-loop) cannot be
enabled.
