DeviceNet Option Fault Monitors U6-98 [First Fault] and U6-99 [Current Fault]
The DeviceNet option can declare error/warning conditions via drive monitor parameters on the drive keypad as
shown in
Table 12.3 .
Table 12.3 DeviceNet Option Fault Monitor Descriptions
Fault Condition Fault Declared

Network Power Loss bUS 1000 Power on DeviceNet network is off.
Connection Time-out
bUS
1001 This nodes timer (Expect Packet Rate) timed out.
Dup MAC ID
bUS
1002
This node and at least one other node have the same MAC ID. Another node sent its
MAC ID to the network first.
Bus Off
bUS
1003 CAN transceiver senses network error.
Two drive monitor parameters, U6-98 [First Fault] and U6-99 [Current Fault] , assist the user in network
troubleshooting.
• U6-98 displays the first declared fault since the last fault reset or power cycle. U6-98 is only cleared upon drive
power-up.
•
U6-99 displays the present option status.
These parameters are accessible from the DeviceNet network or the drive keypad. U6-98 and U6-99 are cleared
upon a drive fault reset and upon power-up.
Note:
In the event of a PLC idle state, the action taken by the DeviceNet Option SI-N3 depends upon the value of parameter F6-54 [Net Idle
Fault Detection] .
