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.
