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 1336 drives encounter a fault, an LED 
is illuminated. Refer to Figure 45. 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.
In addition, A-B 1336 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
NOTE: FOR A-B 1336 ONLY. During normal 
operating conditions (no faults present, drive 
running) the fault contacts at TB2-13 & 14 are 
open, and the contacts at TB2-14 & 15 are closed. 
When a fault occurs, the state of these contacts will 
change. On some machine models, this contact is 
connected to a fault indicator light.
