Fault 45 Fieldbus interface

Subfault: 45.1 Description: No response from fieldbus interface
	Response: Emergency stop + output stage inhibit
Cause	Measure
The fieldbus interface does not start properly and is therefore not functional.	– Switch the device off and on again. – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 45.3 Description: Process output data timeout
	Response: Fieldbus – timeout response
Cause	Measure
Timeout in process data transfer during fieldbus communication.	– Check the communication connection between the fieldbus master and the fieldbus interface for interruption. – Check the configuration of the fieldbus master. – Adjust the timeout monitoring of the fieldbus interface.

Subfault: 45.3

Description: Process output data timeout

Response: Fieldbus – timeout response

Cause

Measure

Subfault: 45.5 Description: Fault in engineering
	Response: Warning
Cause	Measure
Engineering via fieldbus interface no longer works, or only works to a limited extent.	– Switch the device off and on again. – Check the network load in the communications network. – Close unneeded engineering connections that are open in parallel (e.g., parameter access via managing EDGE devices, asset management tools, network scanners, etc.). – If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 45.5

Description: Fault in engineering

Response: Warning

Cause

Measure

Engineering via fieldbus interface no longer works, or only works to a limited extent.

– Switch the device off and on again.

– Check the network load in the communications network.

– Close unneeded engineering connections that are open in parallel (e.g., parameter access via managing EDGE devices, asset management tools, network scanners, etc.).

– If the fault occurs repeatedly, contact SEW‑EURODRIVE Service.

Subfault: 45.7 Description: Invalid process output data
	Response: Fieldbus – timeout response
Cause	Measure
– The fieldbus master sends invalid process output data. – The fieldbus interface has detected an internal fault in the exchange of process data exchange and marks the process output data as invalid.	– Check whether the PLC is in "Stop" state. – Restart the PLC. – Check the configuration of the fieldbus master. – In the event of an error in the internal exchange of process data, switch the device off and then on again.

Subfault: 45.7

Description: Invalid process output data

Response: Fieldbus – timeout response

Cause

Measure

– The fieldbus master sends invalid process output data.

– The fieldbus interface has detected an internal fault in the exchange of process data exchange and marks the process output data as invalid.

– Check whether the PLC is in "Stop" state.

– Restart the PLC.

– Check the configuration of the fieldbus master.

– In the event of an error in the internal exchange of process data, switch the device off and then on again.

Subfault: 45.9 Description: Warning
	Response: Warning
Cause	Measure

Subfault: 45.9

Description: Warning

Response: Warning

Cause

Measure

Inverter detected non-critical fault on device-internal connection to fieldbus interface.

– Switch the device off and on again.

– If the warning occurs repeatedly, contact SEW‑EURODRIVE Service.
