Troubleshooting 8–3
Drive faults can be read via index 0x603F. Refer to Table 8.C Table
8.D for fault number relation.
Drive fault codes can be read by accessing drive parameter P07 - [Last
Fault]. Refer to Table 8.C and Table 8.D for fault descriptions/actions.

Fault Code Fault Indication Description Corrective Action
00 No Fault The drive is currently not faulted. No action required.
03 Power Loss Fault 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.
04 Undervoltage Fault DC Bus voltage fell below the minimum value while
the motor was running.
Monitor incoming AC line for low voltage or line power
interruption.
05 Overvoltage Fault DC Bus maximum voltage exceeded. Bus overvoltage caused by motor regeneration. Extend
the decel time, or install dynamic brake option or external
capacitor module.
06 Motor Stall Fault Motor has stalled. Motor load is excessive. Longer accel time or reduced load required.
07 Motor Overload Fault Internal electronic overload trip. Excessive motor
load exists.
Reduce motor load.
08 Overtemperature Fault Excessive heat detected. Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
11 Operator Fault The keypad has been removed while the drive is
powered.
Clear the fault. Do not remove the keypad underpower.
12 Overcurrent Fault Overcurrent detected in hardware trip circuit. Check short circuit at the drive output or excessive load
conditions at the motor.
13 Software Over
Current Fault
Motor current exceeded value set in parameter 79. A longer acceleration time, reduced load, or removal of
motor shaft blockage is required
20 Drive Overload Fault An internal electronic overload trip has occurred.
The drive is overheating.
Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
22 Drive Reset Stop input not present. Check stop input at TB3 terminal 8.
32 EPROM Fault EPROM has invalid data. Reset EPROM using P56 - [Reset Functions].
33 Max Retries Fault Drive did not reset fault within the specified retries. Repair system fault.
36 Incompatible Fault Incompatible communication module installed. Verify compatibility of communication module.
38 Phase U Fault Phase to ground fault detected between drive and
motor phase U.
Check wiring between drive and motor. Check motor for
grounded phase.
39 Phase V Fault Phase to ground fault detected between drive and
motor phase V.
Check wiring between drive and motor. Check motor for
grounded phase.
40 Phase W Fault Phase to ground fault detected between drive and
motor phase W.
Check wiring between drive and motor. Check motor for
grounded phase.
41 UV Short Fault 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.
42 UW Short Fault 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.
43 VW Short Fault 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.
