Fault Code
Fault
Indication
Description
Corrective Action
50
No DeviceNet
Power
24 volt network power is not detected.
Check DeviceNet connector at Communication Module.
Also, check network’s power supply.
51
DeviceNet Module
EEPROM Fault
DeviceNet Module EEPROM has invalid data.
Reset to factory defaults P56 - [Reset Defaults].
52
DeviceNet Lost
I/O Connection
Polled I/O connection timed out.
Check DeviceNet Master for correct operation (i.e., pow-
ered up, scanner online, etc.).
53
DeviceNet Unre-
coverable Fault
No communication is occurring. Fault occurs when dupli-
cate node address exists or wrong baud rate is set.
Check DIP switch settings for proper baud rate and node
address.
54
DeviceNet Trans-
mit Fault
A transmit timeout occurred.
Power drive off and then cycle power on.

Fault
Indication
Description
Corrective Action
1100
Max Retries Fault Drive failed to reset fault within the max retries specified. Repair system fault.
2213
Power Test
Fault detected during initial start sequence.
Check drive wiring. Check motor wiring. Reset drive to
factory defaults.
2220
Over Current
Overcurrent detected in hardware trip circuit.
Check short circuit at the drive output or excessive load
conditions at the motor.
2331
Phase U
Phase to ground fault detected between drive and motor
phase U.
Check wiring between drive and motor. Check motor for
grounded phase.
2332
Phase V
Phase to ground fault detected between drive and motor
phase V.
Check wiring between drive and motor. Check motor for
grounded phase.
2333
Phase W
Phase to ground fault detected between drive and motor
phase W.
Check wiring between drive and motor. Check motor for
grounded phase.
2341
UV Short
Excessive current has been detected between these two
drive output terminals.
Check the motor and external wiring to the drive output
terminals for a shorted condition.
2342
UW Short
Excessive current has been detected between these two
drive output terminals.
Check the motor and external wiring to the drive output
terminals for a shorted condition.
2343
VW Short
Excessive current has been detected between these two
drive output terminals.
Check the motor and external wiring to the drive output
terminals for a shorted condition.
3120
Power Loss
DC Bus voltage remains below 85% nominal on power up
for longer than 5 seconds.
Monitor incoming AC line for low voltage or line power
interruption.
3210
Over Voltage
DC Bus maximum voltage exceeded.
Bus overvoltage caused by motor regeneration. Extend
the decel time, or install dynamic brake option or external
capacitor module.
3220
Under Voltage
DC Bus voltage fell below the minimum value while the
motor was running.
Monitor incoming AC line for low voltage or line power
interruption.
