Encoder 1: Encoder Evaluation, Internal Software Error - Siemens Sinamics S120 Diagnostic Manual

SINAMICS alarms
Remedy: - check the DRIVE-CLiQ wiring (interrupted cable, contacts, ...).
- check the electrical cabinet design and cable routing for EMC compliance
- if required, use another DRIVE-CLiQ socket (p9904).
- replace the component involved.
231845 <location>Encoder 1 DRIVE-CLiQ: Cyclic data transfer error
Message value: Component number: %1, fault cause: %2
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: ENCODER (IASC/DCBRAKE, NONE)
Acknowledge: IMMEDIATELY
Cause: A DRIVE-CLiQ communication error has occurred from the Control Unit to the encoder involved.
Fault value (r0949, interpret hexadecimal):
yyxx hex: yy = component number, xx = fault cause
xx = 0B hex:
Synchronization error during alternating cyclic data transfer.
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: Carry out a POWER ON.

231850 <location>Encoder 1: Encoder evaluation, internal software error
Message value: %1
Drive object: SERVO_COMBI, SERVO_SINUMERIK828
Reaction: ENCODER (IASC/DCBRAKE, NONE)
Acknowledge: POWER ON
Cause: An internal software error has occurred in the Sensor Module of encoder 1.
Fault value (r0949, interpret decimal):
1: Background time slice is blocked.
2: Checksum over the code memory is not OK.
10000: OEM memory of the EnDat encoder contains data that cannot be interpreted.
11000 ... 11499: Descriptive data from EEPROM incorrect.
11500 ... 11899: Calibration data from EEPROM incorrect.
11900 ... 11999: Configuration data from EEPROM incorrect.
16000: DRIVE-CLiQ encoder initialization application error.
16001: DRIVE-CLiQ encoder initialization ALU error.
16002: DRIVE-CLiQ encoder HISI / SISI initialization error.
16003: DRIVE-CLiQ encoder safety initialization error.
16004: DRIVE-CLiQ encoder internal system error.
