3.2.2 Diagnostics and Troubleshooting
When faults happen, try to restart by resetting the key switch after confirmed that faults are not
caused by faulty wiring connection or mechanical failure. If the faults are still on, shut down the
key, check for incorrect connection or corruption of the pin 35 connecter, reconnect after repaired
and cleared, and then restart again.
The controller provides diagnostics information to assist technicians in troubleshooting drive
system problems. The diagnostics information can be obtained in two ways: by reading the
appropriate display on the programmer or by observing the fault codes issued by the status LED.
Led Diagnostics
During normal operation, with no faults present, the status LED is steadily on. If the controller
detects a fault, the status LED flashes a fault identification code continuously until the fault is
corrected. Refer to the troubleshooting chart for suggestions about possible causes of the various
faults. Faults are listed alphabetically.
Note: The status LED can only indicate one fault at a time. If multiple faults are detected, the
highest priority fault code flashes until it is cleared.
Programmer Diagnostics
The programming devices present complete diagnostic information in plain language. Faults are
displayed in the Faults/Diagnostics menu, and the status of the controller inputs/outputs is
displayed in the Monitor menu.
Additionally, the fault history file in the Faults/Diagnostics menu provides a list of the faults that
have occurred since the file was last cleared. Checking (and clearing) the fault history file is
recommended each time the vehicle is brought in for maintenance.
Refer to the troubleshooting chart for suggestions about possible causes of the various faults.
Faults are listed alphabetically.
Fault Handling
When a fault is detected, the controller operates in a manner that is safe in the presence of that
fault. Depending on the severity of the fault, the response can range from reduction of current to
complete shutdown of drive. The status LED uses a 2-digit code. For example, code
“1,4”—undervoltage—appears as:
¤ ¤¤¤¤ ¤ ¤¤¤¤ ¤ ¤¤¤¤
（
1,4
