PowerFlex 40 and 400 Drive Control Logic

Fault Display and Troubleshooting Information

This section provides information to guide users in understanding drive fault conditions and general troubleshooting procedures for Allen-Bradley drives. Included is a listing and description of the various drive faults with possible solutions, when applicable. For any questions regarding fault conditions, consult with the factory.

Each drive is equipped with a fault indicator light which illuminates when a fault condition exists.

Clearing Faults

When a fault occurs, the cause must be corrected before the fault can be cleared. Resetting a fault will not correct the cause of the fault condition. After corrective action has been taken, simply cycling power to the drive will clear the fault.

When a fault occurs, the fault indicator light on the integral keypad will illuminate. The fault code will immediately be indicated on the display, such as “F005”. The last three fault codes are also stored in the fault memory location as indicated in Table 12. Repetitive faults of the same fault code will only be recorded once.

Refer to Viewing and Editing Parameters section of AC Drive Diagnostics/Parameter Viewing chapter for details on how to access parameter values.

Once a fault code is identified, refer to the AC drive manual for the most up-to-date explanation of codes. Table 20 also contains an abbreviated list of typical fault codes.
