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.

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.

• Clear the external fault input in the MFDI.
Examine cooling fan operation.
• Check reference and reference gain.
• Check F1-08 [Overspeed Detection Level] and F1-09 [Overspeed
Detection Delay Time] settings.
• Check load, acc/dec times and system mechanics.
• Check F1-10 [Speed Deviation Detection Level] and F1-11 [Speed
Deviation Detect DelayTime] settings.
Check PG card connections.
The drive input power voltage is changing too much.
• Check for broken wire/loose terminals.
• Check motor rating.
-
Remove the keypad and connect it again.
• Cycle drive power.
• If the fault stays, replace the drive.
-
• Check DeviceNet network cable connections.
• Check 24 Vdc power supply voltage.
Check DeviceNet Option Card installation and connections.
• Cycle drive power.
• Replace DeviceNet Option or drive if fault continues.
• Check motor parameters.
• Auto-tune
• Examine the operation of the controller program.
• Check MI switch setting.
• Check DeviceNet Option Card LEDs for fault indication.
No Fault
Option card failure.
PLC is sending polled I/O with all data set to zero.
Network sent a message to force this node to the fault state.
Power on DeviceNet network is off.
This nodes timer (Expect Packet Rate) timed out.
This node and at least one other node have the same MAC ID. Another node sent its
MAC ID to the network first.
CAN transceiver senses network error.
