3. Overriding the control panel display with the display of a
fault code
4. Stopping the motor (if it was on)
5. Sets an appropriate bit in Fault Word parameter (0305 to
0307)
The fau lt code on the control p anel display is temporary. Pressing
the MENU, ENTER, UP or DOWN buttons removes the fault
message. The message reappears after a few seconds if the control
panel is not touched and the fault is still active.
Alarms (Green LED Flashing)
For less severe errors, called alarms, the diagnostic display is
advisory. For these situations, the drive is simply reporting that it
had detected something unusual. In these situations, the drive:
1. Flashes the green LED on the drive (does not apply to
alarms that arise from control panel operation errors)
2. Sets an appropriate bit in an Alarm Word parameter (0308
or 0309)
3. Overrides the control panel display with the display of an
alarm code and/or name
Alarm messages disappear from the control panel display after a
few seconds. The message returns periodically as long as the alarm
condition exists.
Correcting Faults
The recommended corrective action for faults is shown in the Fault
Listing Table 33. The VFD can also be reset to remove the fault. If
an external source for a start command is selected and is active, the
VFD may start immediately after fault reset.
To reset a fault indicated by a flashing red LED, turn off the power
for 5 minutes. T o reset a fault indicated by a red LED (not
flashing), press RESET from the control panel or turn off the
power for 5 minutes. Depending on the value of parameter 1604
(FAULT RESET SELECT), digital input or serial communication
could also be used to reset the drive. When the fault has been
corrected, the motor can be started.
History
For reference, the last three fault codes are stored into parameters
0401, 0412, 0413. For the most recent fault (identified by
parameter 0401), the drive stores additional data (in parameters
0402 through 0411) to aid in troubleshooting a problem. For
example, a parameter 0404 stores the motor speed at the time of the
fault. To clear the fault history (all of Group 04, Fault History
parameters), follow these steps:
1. In the control panel, Parameters mode, select parameter
0401.
2. Press EDIT.
3. Press the UP and DOWN buttons simultaneously.
4. Press SAVE.
If diagnostics troubleshooting has determined that the drive is
defective during the warranty period, contact ABB Automation
Inc., at 1 -- 800--435-- 7365, option 4, option 3. A qualified
technician will review the problem with the caller and make a
determination regarding how to proceed. This may involve
dispatching a designated service station (DSS) representative from
an authorized station, dispatching a replacement unit, or advising
return for repair.
