7 - TROUBLE-SHOOTING USING ERROR CODES

Troubleshooting using error codes

The drive can display two kinds of error codes, alarm and fault codes, to signal a problem during self-
tuning or drive operation. Fault and alarm codes are shown in tables 7.1 and 7.2. A special type of fault
code, which occurs rarely, is the fatal fault code. If the code you see is not in tables 7.1 or 7.2, refer to
table 7.5.

Alarms

An alarm is signified by a two- to four- letter code flashing on the display. The drive will continue to
operate during the alarm condition. The user should investigate the cause of the alarm to ensure that it
does not lead to a fault condition. The alarm code will remain on the display only as long as the alarm
condition exists. The alarm will automatically be cleared when the condition causing it is removed.

Faults

A fault condition is also signified by a two- or three- letter code flashing on the display. In the case of a
fault, the drive will not continue to operate, but will coast-to-stop. The RUNNING LED will turn off when
this happens. The first fault that occurs will be maintained flashing on the display, regardless of whether
other faults occur after it. The fault code will remain on the display until it is cleared by the operator
using the STOP/RESET key, or the fault reset input from the selected control source in P.000.
Error at Vector Torque Self-Tuning procedure
If a fault occurs when performing the Vector mode self-tuning, a 'SF' (self-tuning fault) will be entered
into the error log and the type of fault will be indicated in the parameter value of U.009 (Results of
Torque Control Self-Tuning). Refer to Table 7.3 to Access and Read the results from Torque Self-
Tuning procedure.

Error at V/Hz Identification procedure

If a fault occurs at V/Hz mode after the 'Identification Request' (H.020) has been activated, either nId
(Procedure ended with no result) or a HId (Ident. procedure fault) will be entered into the error log and
the type of fault will be indicated in parameter value of H.019 (Results of Ident. Procedure). Refer to
Table 7.4 to Access and Read the results from V/Hz Identification procedure.
Error Log
The drive automatically stores all subsequent fault codes that may occur in the system error log, which
is accessible through the keypad, the OIM or the optional Man Machine Interface CS3000 software. The
error log can be accessed in program mode after moving through all the parameter menus and is
displayed as "Err" on the display. There is no visual indication that there are faults in the log. You must
access the error log to view the faults.
The error log holds the 10 most recent faults that have occurred. The faults in the log are numbered
sequentially (0 up to 9). The last fault to occur is the first one to appear on the display when you access
the error log and is identified with the highest number. Once the log is full, older faults are discarded
from the log as new faults occur.
For example, if the last fault was a Low Bus Voltage, and the log has 10 entries, then the error log would
display first '9.LU' when the error log is accessed.
Time Stamp for Error Log
For each entry in the error log, the system can also display the day and time that the fault occurred. The
day data is based on a relative 248-day counter (rolls over after 248.55). The time is based on a 24-hour
clock. The first two digits of the clock data represent hours, the last two digits represent minutes. The
clock can be reset using P.030 (Elapsed Time Meter Reset).
All the entries in the error log and the day and time data are retained if power is lost.
See section 3 for how to clear the error log and access error time stamp.
