Powerflex 525 OEM Manual:  https://literature.rockwellautomation.com/idc/groups/literature/documents/um/520-um001_-en-e.pdf Fault Codes:
Fault Types, Descriptions, and Actions No. Fault Type(1) Description Action
  • F000
  • No Fault 
  • No fault present.
  • F002
  • Auxiliary Input 1 External trip (Auxiliary) input.
  • Check remote wiring.
  • Verify communications programming for intentional fault.
  • F003
  • Power Loss 2 Single-phase operation detected with excessive load.
  • Monitor the incoming AC line for low voltage or line power interruption.
  • Check input fuses.
  • Reduce load.
  • F004
  • UnderVoltage 1
  • DC bus voltage fell below the min value. Monitor the incoming AC line for low voltage or line power interruption.
  • F005
  • OverVoltage 1
  • DC bus voltage exceeded max value. Monitor the AC line for high line voltage or transient conditions. Bus overvoltage can also be caused by motor regeneration. Extend the decel time or install dynamic brake option.
  • F006
  • Motor Stalled 1
  • Drive is unable to accelerate or decelerate motor.
  • Increase P041, A442, A444, A446 [Accel Time x] or reduce load so drive output current does not exceed the current set by parameter A484, A485 [Current Limit x] for too long.
  • Check for overhauling load.
  • F007
  • Motor Overload 1 Internal electronic overload trip.
  • An excessive motor load exists. Reduce load so drive output current does not exceed the current set by parameter P033 [Motor OL Current].
  • Verify A530 [Boost Select] setting.
  • F008
  • Heatsink OvrTmp 1
  • Heatsink/Power Module temperature exceeds a predefined value.
  • Check for blocked or dirty heatsink fins. Verify that ambient temperature has not exceeded the rated ambient temperature.
  • Check fan.
  • F009
  • CC OvrTmp 1
  • Control module temperature exceeds a predefined value.
  • Check product ambient temperature.
  • Check for airflow obstruction.
  • Check for dirt or debris.
  • Check fan.
  • F012
  • HW OverCurrent 2
  • The drive output current has exceeded the hardware current limit. Check programming. Check for excess load, improper A530 [Boost Select] setting, DC brake volts set too high or other causes of excess current.
  • F013
  • Ground Fault 1 (2)
  • A current path to earth ground has been detected at one or more of the drive output terminals. Check the motor and external wiring to the drive output terminals for a grounded condition.
  • F015(3)
  • Load Loss 2
  • The output torque current is below the value that is programmed in A490 [Load Loss Level] for a time period greater than the time programmed in A491 [Load Loss Time].
  • Verify connections between motor and load.
  • Verify level and time requirements.
  • F021
  • Output Ph Loss 1
  • Output Phase Loss (if enabled). Configure with A557 [Out Phas Loss En].
  • Verify motor wiring.
  • Verify motor.
  • F029
  • Analog In Loss 1
  • An analog input is configured to fault on signal loss. A signal loss has occurred. Configure with t094 [Anlg In V Loss] or t097 [Anlg In mA Loss].
  • Check for broken/loose connections at inputs.
  • Check parameters.
  • F033
  • Auto Rstrt Tries 2
  • Drive unsuccessfully attempted to reset a fault and resume running for the programmed number of A541 [Auto Rstrt Tries]. Correct the cause of the fault and manually clear.
  • F038 Phase U to Gnd 2 A phase to ground fault has been detected between the drive and motor in this phase. • Check the wiring between the drive and motor. • Check motor for grounded phase. • Replace drive if fault cannot be cleared. F039 Phase V to Gnd F040 Phase W to Gnd 
  • F041 Phase UV Short 2 Excessive current has been detected between these two output terminals. • Check the motor and drive output terminal wiring for a shorted condition. • Replace drive if fault cannot be cleared.
  • F042 Phase UW Short F043 Phase VW Short
  • F048 Params Defaulted 1 The drive was commanded to write default values to EEPROM. • Clear the fault or cycle power to the drive. • Program the drive parameters as needed.
  • F059(3) Safety Open 1 Both of the safety inputs (Safety 1, Safety 2) are not enabled. Configure with t105 [Safety
