Cause : Configuration error comes when the configuration for encoder 1 is incorrect. When encountering a "Configuration Error" on a Siemens SINAMICS G120 drive, it indicates that there is an issue with the configuration settings or parameters of the drive.

Alarm value (r2124, interpret decimal):

1: Re-parameterization between fault/alarm is not permissible.

419: When the fine resolution Gx_XIST2 is configured, the encoder identifies a maximum possible absolute position actual value (r0483) that can no longer be represented within 32 bits.

Re alarm value = 1: No re-parameterization between fault/alarm.

Re alarm value = 419: Reduce the fine resolution (p0419) or deactivate the monitoring (p0437.25), if the complete multiturn range is not required.
