Fault
Indication
Description
Corrective Action
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. Check for high line voltage.
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.
4310
Over Temperature
Excessive heat detected.
Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
5300
Drive Reset
Stop input not present.
Check stop input at TB3 terminal 8.
6310
EEPROM Fault
EEPROM has invalid data.
Reset EEPROM.
6311
DeviceNet Module
EEPROM Fault
DevicNet 160-DN2 module EEPROM has invalid data.
Reset to factory defaults using P56 - [Reset Defaults].
7121
Motor Stalled
Motor has stalled. Motor load is excessive.
Longer accel time or reduced load required.
7122
Motor Overload
Internal electronic overload trip. Excessive motor load
exists.
Reduce motor load.
7421
Reprogramming
Fault
Occurs when drive parameters are reset to defaults.
Clear fault.
7500
No DeviceNet Power 24 volt network power is not detected.
Check DeviceNet connector at module. Also, check the
network’s power supply.
7501
DeviceNet Lost
I/O Connection
Polled I/O connection timed out.
Check DeviceNet Master for correct operation (i.e.,
powered up, scanner online, etc.).
7502
DeviceNet
Unrecoverable Fault
No communication is occurring. Fault occurs when
duplicate node address exists or wrong baud rate is set.
Check DIP switch settings for proper baud rate and node
address.
7503
DeviceNet Transmit
Fault
A transmit timeout occurred.
Power drive off, and then cycle power on.
7504
DN Forced Fault
DeviceNet module forced a fault.
Clear fault.
