Meaning
A084 CB
alarm
Possible cause:
Errored CAN messages are being received or transmitted and the
internal error counter has exceeded the fault limit.
The errored CAN messages are ignored. The data last transmitted
remain valid. If the errored CAN messages are process data, the
message failure monitoring function (P722) may respond with error
F082 (DPR message failure). If the PKW CAN messages are
errored, the converter does not respond.
Remedial measure:
•
Check parameter P720 (baud rate) for every node and correct if
necessary.
•
Check the CAN bus master.
•
Check the cable connection between bus nodes.
•
Check the cable shield. The bus cable must be shielded at both
ends.
•
Reduce electromagnetic interference.
•
Replace the CBC board.
