PowerFlex 525 Fault Codes Guide

Always confirm the code on the drive display or in Connected Components Workbench or Studio 5000 against Rockwell documentation for the installed model and firmware. Fault numbers and corrective actions should be verified before a reset or parameter change. This table is a first-check reference, not a substitute for the manufacturer’s manual or site safety procedure.

Code	Typical meaning	First checks
F003	Power loss	Incoming power, disconnect, fuses, undervoltage events, and the fault timestamp
F004	Undervoltage	Supply voltage, wiring, shared transformer loading
F005	Overvoltage	Decel too aggressive, regen, high line voltage
F006	Motor stalled	Mechanical bind, boost, current limit, load
F007	Motor overload	Motor FLA vs parameter, duty cycle, cooling
F008	Heatsink overtemp	Fan, ambient, enclosure heat, mounting
F012	HW overcurrent	Shorted motor leads, ground, failed motor
F013	Ground fault	Motor insulation, cable damage, moisture
F081	Comm loss	EtherNet/IP adapter, PLC inhibit, cable, switch, and connection status

How to use a fault code

Record the code before resetting it, including whether it occurred during acceleration, steady operation, or stopping. Check the drive display, fault queue, motor current, process load, and recent changes. A reset may restore production temporarily while removing evidence of the original condition.

Power loss and undervoltage faults require attention to supply and power quality. Overvoltage may relate to deceleration or regeneration. Overload and stall faults require motor data, mechanical load, cooling, and acceleration checks. Ground and overcurrent faults require qualified electrical investigation of motor leads, insulation, and the drive.
