Fault Codes
Fault
No.
Fault Indication and Corrective Action
03
Power Loss Fault
Monitor incoming AC line for low voltage or line power
interruption.
04
➊
UnderVoltage Fault
Monitor incoming AC line for low voltage or line power
interruption.
05
➊
OverVoltage Fault
Bus overvoltage caused by motor regeneration. Monitor
incoming AC line for excessive voltage. Extend the decel
time or install dynamic brake module or external capaci-
tor module.
06
➊
Motor Stall Fault
Longer acceleration time or a reduced load required.
07
➊
Motor Overload Fault
Reduce motor load until drive output current does not
exceed the current set by P42 - [Motor Overload
Current]. Reduce P38 - [Boost Select].
08
➊
Over Temperature Fault
Clear blocked or dirty heat sink fins. Check ambient tem-
perature. Check for blocked or non-operating fan.
11
Operator Error
Clear fault. Do not remove keypad under power.
12
➊
Overcurrent FauIt
Check short circuit at the drive output or excessive load
conditions at the motor.
13
➊
Software Overcurrent Fault
A longer acceleration time, reduced load, or removal of
motor shaft blockage is required.

➊
Drive Overload Fault
Clear blocked or dirty heat sink fins. Check ambient tem-
perature. Check for blocked or non-operating fan.
Reduce motor load current.
32
EEPROM Fault
Reset EEPROM using P56 - [Reset Functions]. Set to 1.
Cycle Power
33
Max Retries Fault
Repair system fault.
36
Incompatible Fault
Check the wiring between the drive and the motor.
Check the motor for a grounded phase.
38
Phase U Fault
Check the wiring between the drive and motor. Check
motor for grounded phase.
39
Phase V Fault
Check the wiring between the drive and motor. Check
motor for grounded phase.
40
Phase W Fault
Check the wiring between the drive and motor. Check
motor for grounded phase.
41
UV Short Fault
Check the motor and external wiring to the drive output
terminals for a shorted condition.
42
UW Short Fault
Check the motor and external wiring to the drive output
terminals for a shorted condition.
43
VW Short Fault
Check the motor and external wiring to the drive output
terminals for a shorted condition.
46
Intermittent Power Output Fault
Check the wiring between the drive and motor. Check
the motor for more than one shorted output.
48
Reprogram Fault
Clear fault.
➊
These faults have an auto reset feature. This feature automatically clears overvolt-
age, undervoltage and overtemperature faults 1 second after the fault condition is
removed. Refer to P51 - [Restart Time].
