Troubleshooting
The ACS880+N5350 will annunciate events that are abnormal during operation as a warnings or fault. The codes and names
of active warnings/faults are displayed on the control panel of the drive. Only the codes of warnings/faults are available over
eldbus.
The chapter lists the warning and fault messages including possible causes and corrective actions. The causes of most
warnings and faults can be identied and corrected using the information in this chapter.
13.1 Warnings and Faults
Warnings do not need to be reset; they stop showing when the cause of the warning ceases. Warnings do not latch and the
drive will continue to operate the motor.
Faults do latch inside the drive and cause the drive to trip, and the motor stops. After the cause of a fault has been removed,
the fault can be reset from a selectable 386 Fault tracing source (see parameter 31.11 Fault reset selection) such as the
control panel, Drive composer PC tool, the digital inputs of the drive, or eldbus. After the fault is reset, the drive can be
restarted.
13.1.1 Pure Events
In addition to warnings and faults, there are pure events that are only recorded in the event log of the drive. The codes of
these events are included in the Warning messages table.
13.1.2 Editable Messages
For some warnings and faults, the message text can be edited and instructions and contact information added. To edit these
messages, choose Menu - Settings - Edit texts on the control panel.
13.2 Warning/Fault History
13.2.1 Event Log
All indications are stored in the event log with a time stamp and other information. The event log can be accessed from the
main Menu on the control panel. It can also be accessed (and reset) using the Drive composer PC tool. In Drive composer,
some faults are presented with additional data recorded prior to the fault; refer to Drive composer Start-up and maintenance
PC tool User’s manual (3AUA0000094606.
13.2.2 Auxiliary Codes
Some events generate an auxiliary code that often helps in pinpointing the problem. On the control panel, the auxiliary code
is stored as part of the details of the event; in the Drive composer PC tool, the auxiliary code is shown in the event listing.
13.2.3 Parameters that Contain Warning/Fault Information
The drive is able to store a list of the active faults actually causing the drive to trip at the present time. The faults are
displayed in parameter group 04 Warnings and faults. The parameter group also displays a list of faults and warnings that
have previously occurred.
