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.

20 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].
