A30999
Power unit: Unknown alarm
Message class:
Power electronics faulted (5)
Message value:
New message: %1
Component:
Power Unit
Response:
NONE
Acknowledgment: NONE
Cause:
An alarm has occurred on the power unit, which cannot be interpreted by the converter firmware.
This can occur if the firmware on this component is more recent than the firmware on the converter.
Alarm value (r2124, interpret decimal):
Alarm number.
Note:
If required, the significance of this new alarm can be read about in a more recent description of the converter.
Remedy:
- Replace the firmware on the power unit by an older firmware version.
- Upgrade the converter firmware.
F31110
Motor encoder: Serial communication faulted
Message class:
Position/speed actual value incorrect or not available (11)
Message value:
Fault cause: %1 bin
Component:
Encoder 1
Response:
ENCODER
Acknowledgment: PULSE INHIBIT
Cause:
There is an error in the transfer of the serial communication protocol between the encoder and internal or external
evaluation module.
Fault value (r0949, interpret binary):
Bit 0: Alarm bit in the position protocol.
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 6: Timeout when cyclically reading.
Bit 7: Timeout for the register communication.
Bit 14: Register communication error.
Remedy:
For fault value, bit 0 = 1:
- Encoder defect F31111 may provide further details.
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 6 = 1:
- Update the firmware
For fault value, bit 7 = 1:
- Incorrect encoder type / replace the encoder or encoder cable.
For fault value, bit 14 = 1:
- Incorrect encoder type / replace the encoder or encoder cable.
