Communication / CBC CANopen Communication Board
Alarm 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.
A085 CB alarm
A "Life guarding event" has occurred. The converter has changed
state according to the setting in P719.
Cause: No node guarding messages have been received from the
master.
A086 CB alarm
The PDO received is shorter than the parameterized PDO. Alarm
A086 has been activated. The identifier to which the alarm applies
is displayed in bytes 6 and 7 (fault value). The alarm will be
canceled again when the next PDO is positively received.
