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 DeviceNetModule
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 Busvoltageremains below85% nominalon powerup
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 installdynamic brake optionor 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.
