Error: 45.7 (2D07hex \| 11527dec) 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 failure of the 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 a failure of the internal process data exchange, switch the device off and then on again.

Error: 45.7 (2D07hex | 11527dec)

Description: Invalid process output data

Response: Fieldbus – timeout response

Cause

Measure

– The fieldbus master sends invalid process output data.

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

– Restart the PLC.

– Check the configuration of the fieldbus master.

– In the event of a failure of the internal process data exchange, switch the device off and then on again.

Error: 45.9 (2D09hex \| 11529dec) Description: Warning
	Response: Warning
Cause	Measure
The inverter has detected a non-critical fault on the device-internal connection to the fieldbus interface.	– Switch the device off and on again. – If the warning occurs repeatedly, contact SEW‑EURODRIVE Service.
