List Manual (LH2), 07/2016, A5E03263479A
A31920 (F, N) Encoder 1: Temperature sensor fault
Message value: Fault cause: %1, channel number: %2
Message class: External measured value / signal state outside the permissible range (16)
Drive object: B_INF, ENC, VECTOR_G
Component: Sensor Module Encoder 1 Propagation: LOCAL
Reaction: NONE
Acknowledge: NONE
Cause: When evaluating the temperature sensor, an error occurred.
Fault cause:
1 (= 01 hex):
Wire breakage or sensor not connected.
KTY: R > 1630 Ohm, PT1000: R > 1720 Ohm
2 (= 02 hex):
Measured resistance too low.
PTC: R < 20 Ohm, KTY: R < 50 Ohm, PT1000: R < 603 Ohm
Additional values:
Only for internal Siemens troubleshooting.
Note regarding the message value:
The individual information is coded as follows in the message value (r0949/r2124):
0000yyxx hex: yy = channel number, xx = error cause
See also: p0491 (Motor encoder fault response ENCODER)
Remedy: - check that the encoder cable is the correct type and is correctly connected.
- check the temperature sensor selection in p0600 to p0603.
- replace the Sensor Module (hardware defect or incorrect calibration data).
Reaction upon F: Vector: NONE (ENCODER, IASC/DCBRK, OFF1, OFF2, OFF3, STOP2)
Infeed: NONE (OFF1, OFF2)
Acknowl. upon F: IMMEDIATELY
Reaction upon N: NONE
Acknowl. upon N: NONE
A31930 (N) Encoder 1: Data logger has saved data
Message value: -
Message class: Error in the parameterization / configuration / commissioning procedure (18)
Drive object: B_INF, ENC, VECTOR_G
Component: Sensor Module Encoder 1 Propagation: GLOBAL
Reaction: NONE
Acknowledge: NONE
Cause: For the activated function "Data logger" (p0437.0 = 1) a fault has occurred with the Sensor Module. This alarm
indicates that the diagnostics data corresponding to the fault was saved on the memory card.
The diagnostics data is saved in the following folder:
/USER/SINAMICS/DATA/SMTRC00.BIN
...
/USER/SINAMICS/DATA/SMTRC07.BIN
/USER/SINAMICS/DATA/SMTRCIDX.TXT
The following information is contained in the TXT file:
- Display of the last written BIN file.
- Number of write operations that are still possible (from 10000 downwards).
Note:
Only Siemens can evaluate the BIN files.
Remedy: Not necessary.
The alarm disappears automatically.
The data logger is ready to record the next fault case.
Reaction upon N: NONE
Acknowl. upon N: NONE
