F31905 Motor encoder: Encoder parameterization error
Message class: Error in the parameterization / congur
ation / commis
sioning pr
ocedure (18)
Message value: Parameter: %1, supplementary information: %2
Component: Sensor Module Encoder 1
Response: ENCODER
Acknowledgment: IMMEDIATELY
Cause: An error was identied in t
he encoder parame
terization.
It is possible that the parameterized encoder type does not match the connected encoder.
Determine the parameter number using the fault value (r0949).
Fault value (r0949, interpret decimal):
yyyyxxxx dec: yyyy = supplementary information, xxxx = parameter
yyyy = 0:
No additional information available.
yyyy = 10:
The connected encoder is not supported.
Remedy: - Check whether the connected encoder type matches the encoder that has been parameterized.
- Correct t
he parameter specied by the fault value (r0949).
F31950 Motor encoder: Internal software error
Message class: Hardware/software error (1)
Message value: %1
Component: Sensor Module Encoder 1
Response: ENCODER
Acknowledgment: POWER ON
Cause: An internal software error has occurred.
F
ault value (r0949, int
erpret decimal):
The fault value contains information regarding the fault source.
Only for internal Siemens troubleshooting.
