Siemens SINAMICS S200 - Page 476

Cause: The logic unit of the DRIVE-CLiQ encoder has failed.
Fault value (r0949, interpre
t binary):
Bit 0: ALU watchdog has responded.
Bit 1: ALU has detected a sign-of-life error.
Remedy: When the error reoccurs, replace the encoder.
F31850 Motor encoder: Encoder evaluation 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 in the Sensor Module of the motor encoder.
F
ault value (r0949, interpre
t decimal):
1: Background time slice is blocked.
2: Checksum over the code memory is not correct.
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: Con󹪝guration data from EEPROM incorrect.
12000 ... 12008: communication with analog/digital converter faulted.
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.
Remedy: - Replace the Sensor Module.
- If required, upgr
ade the 󹪝rmware.
- Contact Technical Support.
F31899 Motor encoder: Unknown fault
Message class: Position/speed actual value incorrect or not available (11)
Message value: New message: %1
Component: Sensor Module Encoder 1
Response: ENCODER
Acknowledgment: IMMEDIATELY
Cause: A fault has occurred on the Sensor Module for the motor encoder, which cannot be interpreted by the Control Unit 󹪝rm
ware.
This can occur if the 󹪝rm
ware on this component is more recent than the 󹪝rmware on the Control Unit.
Fault value (r0949, interpret decimal):
Fault number.
Note:
If required, the signi󹪝cance of this new fault can be read about in a more recent description of the Control Unit.
Remedy: - Replace the 󹪝rmware on the Sensor Module b
y an older 󹪝rmware version (r0148).
- Upgrade the 󹪝rmware on the Control Unit (r0018).
A31902 Motor encoder: SPI-BUS error occurred
Message class: Hardware/software error (1)
Message value: %1
Component: Sensor Module Encoder 1
Response: NONE
