Mes
sage value: Parameter: %1, supplementary information: %2
Component: Sensor Module Encoder 1
Response: ENCODER
Acknowledgment: IMMEDIATELY
Cause: An error was identi󹪝ed in t
he encoder parameter
ization.
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 the parame
ter speci󹪝ed 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, interpre
t decimal):
The fault value contains information regarding the fault source.
