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.
