Cause: A time slice overo
w 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 overow of the fast (current controller clock cycle) time slice.
x = A:
Time slice overow of the average time slice.
x = C:
Time slice overow 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:
F
or 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.
F
ault v
alue (r0949, int
erpret hexadecimal):
yyyyxxxx hex
yyyy: Memory area involved.
xxxx: Dierence between the checksum at POWER ON and the actual checksum.
Remedy: - Carry out a POWER ON (switch-o/switch-on).
- U
pgrade rmware 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 .
F
ault 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
