Faults and Alarms
List of faults and alarms
Cause:
The memory or the buffer status of the message channel has an error.
Alarm value (r2124, decimal):
0: Error in the buffer status.
1: Error in the memory.
Remedy:
Check communication line.
Reaction upon F:
NONE (OFF1, OFF2, OFF3)
Acknowledge
IMMEDIATELY
upon F:
A08700 (F)
CBC: Communications error
Reaction:
NONE
Acknowledge:
NONE
Cause:
A CAN communications error has occurred.
Fault value (r0949, decimal):
1: The error counter for the send telegrams has exceeded the BUS OFF value 255. The bus disables the CAN con-
troller.
- bus cable interrupted.
- bus cable not connected.
- incorrect baud rate.
- incorrect bit timing.
2: The master no longer interrogated the CAN node status longer than for its "life time". The "life time" is obtained
from the "guard time" (p8604[0]) multiplied by the "life time factor" (p8604[1]).
- bus cable interrupted.
- bus cable not connected.
- incorrect baud rate.
- incorrect bit timing.
- master fault-
Remedy:
- check the bus cable
- check the baud rate (p8622).
- check the bit timing (p8623).
- check the master.
Reaction upon F:
NONE (OFF1, OFF2, OFF3)
Acknowledge
IMMEDIATELY
upon F:
A08751
CBC: Telegram loss
Reaction:
NONE
Acknowledge:
NONE
Cause:
The CAN controller has lost a receive message (telegram).
Remedy:
- reduce the cycle times of the receive messages
A08752
CBC: Error counter for error passive exceeded
Reaction:
NONE
Acknowledge:
NONE
Cause:
The error counter for the send or receive telegrams has exceeded the value 127.
Remedy:
- check the bus cable
- set a higher baud rate (p8622).
- check the bit timing and if required optimize (p8623).
A08753
CBC: Message buffer overflow
Reaction:
NONE
Acknowledge:
NONE
Cause:
A message buffer has overflowed.
Alarm value (r2124, decimal):
1: Non-cyclic send buffer (SDO response buffer) has overflowed.
2: Non-cyclic receive buffer (SDO receive buffer) has overflowed.
3: Cyclic send buffer (SDO response buffer) has overflowed.
