12.3 Faults and alarms
Cause:
A time slice overflow for the motor encoder has occurred.
Fault value (r0949, interpret hexadecimal):
yx hex: y = function involved (Siemens-internal fault diagnostics), x = time slice involved
x = 9:
Time slice overflow of the fast (current controller clock cycle) time slice.
x = A:
Time slice overflow of the average time slice.
x = C:
Time slice overflow of the slow time slice.
yx = 3E7:
Timeout when waiting for SYNO (e.g. unexpected return to non-cyclic operation).
Remedy:
Increase the current controller sampling time
Note:
For a current controller sampling time = 31.25 µs, use an SMx20 with Article No. 6SL3055-0AA00-5xA3.
F31804
Motor encoder: Sensor Module checksum error
Message class:
Hardware/software error (1)
Message value:
%1
Component:
Sensor Module Encoder 1
Response:
ENCODER
Acknowledgment: POWER ON
Cause:
A checksum error has occurred when reading-out the program memory on the Sensor Module.
Fault value (r0949, interpret hexadecimal):
yyyyxxxx hex
yyyy: Memory area involved.
xxxx: Difference between the checksum at POWER ON and the actual checksum.
Remedy:
- Carry out a POWER ON (switch-off/switch-on).
- Upgrade firmware to later version.
- Check whether the permissible ambient temperature for the component is maintained.
F31805
Motor encoder: EEPROM checksum error
Message class:
Hardware/software error (1)
Message value:
%1
Component:
Sensor Module Encoder 1
Response:
ENCODER
Acknowledgment: IMMEDIATELY
Cause:
Data in the EEPROM corrupted .
Fault value (r0949, interpret hexadecimal):
01: EEPROM access error.
02: Too many blocks in the EEPROM.
Remedy:
Replace the module.
F31813
Motor encoder: Hardware logic unit failed
Message class:
Hardware/software error (1)
Message value:
Fault cause: %1 bin
Component:
Sensor Module Encoder 1
Response:
ENCODER
Acknowledgment: PULSE INHIBIT
