Fault Description Corrective Action
03 Power Loss Fault The DC Bus voltage remains below 85% nominal on
power up for longer than 5 seconds. Monitor the incoming AC line for low voltage or line power
interruptions.
04 ➊ UnderVoltage
Fault The DC Bus voltage fell below the minimum rated
voltage. For 200-240VAC input drives, the under-
voltage trip occurs at a bus voltage of 210VDC (equiv-
alent to a 150VAC incoming line voltage). For 380-
460VAC rated drives, the undervoltage trip occurs at
a bus voltage of 390VDC (equivalent to a 275VAC
incoming line voltage). Monitor the incoming AC line for low voltage or line power
interruptions.
05 ➊ OverVoltage Fault The maximum DC Bus voltage has been exceeded.
For 200-240VAC input drives, the overvoltage trip
occurs at a bus voltage of 400VDC (equivalent to a
290VAC incoming line voltage). For 380-460VAC
input drives, the overvoltage trip occurs at a bus
voltage of 800VDC (equivalent to a 575VAC incoming
line voltage). Motor regeneration has caused a bus overvoltage. Monitor
the incoming AC line for excessive voltage. Extend the
decel time or install a dynamic brake module or external
capacitor module (See Appendix A).
06 ➊ Motor Stall Fault The motor has stalled due to an excessive motor load. A longer acceleration time or a reduced load is required.
07 ➊ Motor Overload
Fault An internal electronic overload trip has occurred. An
excessive motor load exists. Reduce the motor load until the drive output current does
not exceed the current set by P42 - [Motor Overload
Current]. Reduce P38 - [Boost Select].
08 ➊ Over Temperature
Fault Excessive heat has been detected. Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for a 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 under power.
12
➊ Overcurrent Fault An overcurrent has been detected in the hardware trip
circuit. Check for a short circuit at the drive output or for excessive
load conditions at the motor.
13
➊ 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
➊ Drive Overload
Fault An internal electronic overload trip has occurred. The
drive is over heating. Clear blocked or dirty heat sink fins. Check ambient
temperature. Check for blocked or non-operating fan.
Reduce motor load current.
32 EEPROM Fault The EEPROM has invalid data. Reset EEPROM using P56 - [Reset Functions] — Set to
1 and cycle power.
33 Max Retries Fault The drive failed to reset within the number of retries
set in P50 - [Restart Tries]. Repair the system fault.
36 Incompatible Fault Incompatible communication module installed. Verify compatibility of communication module.
38 Phase U Fault A phase to ground fault has been detected between
the drive and the motor in phase U. Check the wiring between the drive and the motor. Check
the motor for a grounded phase. Check that ground is not
connected to U.
39 Phase V Fault A phase to ground fault has been detected between
the drive and the motor in phase V. Check the wiring between the drive and the motor. Check
the motor for a grounded phase.
40 Phase W Fault A phase to ground fault has been detected between
the drive and the motor in phase W. Check the wiring between the drive and the motor. Check
the motor for a 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 Reprogram Fault Occurs when the drive parameters are reset to default. Clear the fault.
➊
These faults have an auto reset feature. This feature automatically clears overvoltage, undervotage, and overtemperature faults
1 second after the fault condition is removed. Refer to P51 - [Restart Time].
