Fault Code
Fault
Indication
Description Corrective Action
43 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.
46 Intermittent Phase
Fault
An external short occurred while running diagnostics. Check wiring between the drive and the motor. Check for
more than one shorted output.
48 Reprogramming
Fault
Occurs when reset defaults is performed. Clear fault.
50 No DeviceNet Power 24 volt network power is not detected. Check DeviceNet connector at module. Also, check the
network’s power supply.
51 DeviceNet Module
EEPROM Fault
DeviceNet 160-DN2 module EEPROM has invalid data. Reset to factory defaults P56 - [Reset Functions] .
52 DeviceNet Lost
I/O Connection
Polled I/O connection timed out. Check DeviceNet Master for correct operation (i.e.,
powered up, scanner online, etc.).
53 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.
54 DeviceNet Transmit
Fault
A transmit timeout occurred. Power drive off and then cycle power on.
55 Forced Fault Control Supervisor Object (Class Code 0x29) attribute
17 was set to 1. Clear fault.
56 Drive Incompatibility
Fault
The 160-DN2 module is not compatible with the 160
SSC drive firmware version (e.g., Series C FRN 7.02) Replace the drive.

Fault
Indication
Description Corrective Action
1100 Max Retries Fault Drive failed to reset fault within the maximum 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.
