CAN: Telegram loss
Message class:
Communication error to the higher-level control system (9)
Reaction:
NONE
Acknowledge:

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
CAN: Message buffer overflow
Message class:
Communication error to the higher-level control system (9)
Reaction:
NONE
Acknowledge:
NONE
Cause:
A message buffer overflow.
Alarm value (r2124, interpret decimal):
1: Non-cyclic send buffer (SDO response buffer) overflow.
2: Non-cyclic receive buffer (SDO receive buffer) overflow.
3: Cyclic send buffer (PDO send buffer) overflow.
Remedy:
- check the bus cable.
- set a higher baud rate (p8622).
- check the bit timing and if required optimize (p8623).
For alarm value = 2:
- reduce the cycle times of the SDO receive messages.
- SDO request from master only after SDO feedback for previous SDO request.

A08754
CAN: Incorrect communications mode
Message class:
Error in the parameterization / configuration / commissioning procedure (18)
Reaction:
NONE
Acknowledge:
NONE
Cause:
In the "operational" mode, an attempt was made to change parameters p8700 ... p8737.
Remedy:
Change to the "pre-operational" or "stopped" mode.
