CBD Alarms and faults

6.1.1

Alarms

Alarm A081:
A zero length PZD data telegram has been received through either the poll or bit strobe I/O message channel. The
alarm will be reset when a normal length PZD data telegram is received.
Effect: The telegram is ignored. Data which was last sent remains valid. Depending on the telegram failure
monitoring setting ("CB/TB TLg OFF Time"), fault F082 can be initiated (DPR telegram failure).
Counter-measures:
♦ Check the DeviceNet™ bus master. Some PLCs will send an idle condition when they are put in the "program"
mode.
Alarm A083:
Erroneous DeviceNet™ CAN messages are received or sent and the internal fault counter has exceeded the alarm
limit.
Effect: The erroneous CAN messages are ignored. Data which was last sent remains valid. If it involves
process data in the erroneous CAN messages, depending on the telegram failure monitoring setting
("CB/TB TLg OFF Time"), fault F082 can be initiated (DPR telegram failure). There is no response
in the drive if the PKW Object or other DeviceNet™ explicit messages are erroneous.
Counter-measures:
♦ Check and if required correct parameter "CB parameter 10" (baud rate) for every bus node.
♦ Check the cable connection between the bus nodes
♦ Check the cable shielding. Follow DeviceNet™ specifications.
♦ Replace board CBD
