Siemens SINAMICS S210 User Manual

Cause: Serial communication protocol transfer error between the encoder and evaluation module.
Fault value (r0949, interpret binary):
Bit 0: Alarm bit in the position protocol.
Bit 1: Incorrect quiescent level on the data line.
Bit 2: Encoder does not respond (does not supply a start bit within 50 ms).
Bit 3: CRC error: The checksum in the protocol from the encoder does not match the data.
Bit 4: Encoder acknowledgment error: The encoder incorrectly understood the task (request) or cannot execute it.
Bit 5: Internal error in the serial driver: An illegal mode command was requested.
Bit 6: Timeout when cyclically reading.
Bit 7: Timeout for the register communication.
Bit 8: Protocol is too long (e.g. > 64 bits).
Bit 9: Receive buffer overflow.
Bit 10: Frame error when reading twice.
Bit 11: Parity error.
Bit 12: Data line signal level error during the monoflop time.
Bit 13: Data line incorrect.
Bit 14: Fault for the register communication.
Bit 15: Internal communication error.
Note:
For an EnDat 2.2 encoder, the significance of the fault value for F3x135 (x = 1, 2, 3) is described.
Remedy: For fault value, bit 0 = 1:
- Enc defect F31111 may provide additional details.
For fault value, bit 1 = 1:
- incorrect encoder type / replace the encoder or encoder cable.
For fault value, bit 2 = 1:
- incorrect encoder type / replace the encoder or encoder cable.
For fault value, bit 3 = 1:
- EMC / connect the cable shield, replace the encoder or encoder cable.
For fault value, bit 4 = 1:
- EMC / connect the cable shield, replace the encoder or encoder cable, replace the Sensor Module.
For fault value, bit 5 = 1:
- EMC / connect the cable shield, replace the encoder or encoder cable, replace the Sensor Module.
For fault value, bit 6 = 1:
- Update Sensor Module firmware.
For fault value, bit 7 = 1:
- incorrect encoder type / replace the encoder or encoder cable.
For fault value, bit 8 = 1:
- check parameterization (p0429.2).
For fault value, bit 9 = 1:
- EMC / connect the cable shield, replace the encoder or encoder cable, replace the Sensor Module.
For fault value, bit 10 = 1:
- check parameterization (p0429.2, p0449).
For fault value, bit 11 = 1:
- check parameterization (p0436).
For fault value, bit 12 = 1:
- check parameterization (p0429.6).
For fault value, bit 13 = 1:
- check data line.
For fault value, bit 14 = 1:
- incorrect encoder type / replace the encoder or encoder cable.
