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.
Fault Code Identification
When the A-B 1305 drives encounter a fault, an LED
is illuminated. Refer to Figure 46 and Figure 45,
respectively. These LEDs are viewed with the front
cover removed. To view the specific fault description,
the HIM (parameter unit) must be installed. Refer to
HIM installation and operation.
Once the HIM is installed, the current fault condition
is displayed as shown below with the corresponding
fault code. Cross reference the number in Table 45 for
fault identification and possible corrective action.
In addition, A-B 1305 fault codes are stored in a fault
buffer with the capability to store up to four fault
codes. If more than four faults are identified, the least
recent fault is deleted to make room for the additional
fault. “Fault Buffer 0” is the most recent fault. The
faults are viewed using a HIM as shown below. Refer
to HIM installation and operation
.
The fault parameters are identified as follows:
“Last Fault” Parameter #4 Most Recent
“Fault Buffer 0” Parameter #86 Most Recent
(same as
Parameter #4)
“Fault Buffer 1” Parameter #87 —
“Fault Buffer 2” Parameter #88 —
“Fault Buffer 3” Parameter #89 Least Recent
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.
