SINAMICS DCP
418 List Manual (LH21), 05/2016
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 topologies:
- change over the actual topology to match the target topology.
- download the target topology that matches the actual topology (commissioning software).
Re byte cc:
cc = 1 --> can be acknowledged using p9904 or p9905.
cc > 1 --> can be acknowledged using p9905 and can be de-activated using p9906 or p9907/p9908.
Note:
Under "Topology --> Topology view" the commissioning software where relevant offers improved diagnostics
capability (e.g. setpoint/actual value comparison).
A01428 Topology: Incorrect connection used
Drive object: CU_DCP, TM150, TM15DI_DO, TM31
Cause: The topology comparison has detected differences in the actual and target topologies in relation to one component.
For a component, another connection was used.
The different connections of a component are described in the alarm value.
Alarm value (r2124, interpret hexadecimal):
ddccbbaa hex:
dd = connection number of the target topology (%4)
cc = connection number of the actual topology (%3)
bb = component class (% 2)
aa = component number (%1)
Note:
Component class 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: Adapting topologies:
- reinsert the DRIVE-CLiQ cable to the component (correct the actual topology).
- adapt the project/parameterization in the commissioning software (correct the target topology).
- automatically remove the topology error (p9904).
Note:
Under "Topology --> Topology view" the commissioning software where relevant offers improved diagnostics
capability (e.g. setpoint/actual value comparison).
F01451 Topology: Target topology is invalid
Drive object: CU_DCP, TM150, TM15DI_DO, TM31
Cause: An error was detected in the target topology.
The target topology is invalid.
Fault value (r0949, interpret hexadecimal):
ccccbbaa hex: cccc = index error, bb = component number, aa = fault cause
aa = 1B hex = 27 dec: Error not specified.
aa = 1C hex = 28 dec: Value illegal.
aa = 1D hex = 29 dec: Incorrect ID.
aa = 1E hex = 30 dec: Incorrect ID length.
aa = 1F hex = 31 dec: Too few indices left.
aa = 20 hex = 32 dec: component not connected to Control Unit.
Remedy: Reload the target topology using the commissioning software.
A01481 (N) Topology: power unit not inserted
Drive object: CU_DCP, TM150, TM15DI_DO, TM31
Cause: The topology comparison has detected a power unit that is missing in the actual topology with respect to the target
topology.
