11.3 Faults and alarms
Cause:
The logic unit of the DRIVE-CLiQ encoder has failed.
Fault value (r0949, interpret 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.
Fault value (r0949, interpret 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: Configuration 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, upgrade the firmware.
- 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 firmware.
This can occur if the firmware on this component is more recent than the firmware on the Control Unit.
Fault value (r0949, interpret decimal):
Fault number.
Note:
If required, the significance of this new fault can be read about in a more recent description of the Control Unit.
Remedy:
- Replace the firmware on the Sensor Module by an older firmware version (r0148).
- Upgrade the firmware 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
