10.2.3 Indicating
and
Rectifying Faults
The cabinet unit features a wide range of functions that protect the drive against
damage if a fault occurs (faults and alarms).
Indicating Faults and Alarms
If a fault occurs, the drive indicates the fault and/or alarm on the cabinet operator
panel. Faults are indicated by the red "FAULT" LED and a fault screen is
automatically displayed. You can use the F1 Help function to call up information
about the cause of the fault and how to remedy it. You can use F5 Ack. to
acknowledge a stored fault.
Any alarms are displayed by the yellow flashing "ALARM" LED. The system also
displays a note in the status bar providing information on the cause.
Every fault and alarm is entered in the fault/alarm buffer along with time the error
occurred and the time it was rectified. The time stamp relates to the relative system
time in milliseconds (r0969).
What is a Fault?
A fault is a message from the drive indicating an error or other exceptional
(unwanted) status. This could be caused by a fault within the converter or an
external fault triggered, for example, from the winding temperature monitor for the
asynchronous motor. The faults are displayed and can be reported to a higher-level
control system via PROFIBUS. In the factory default setting, the message
"converter fault" is also sent to a relay output. Once you have rectified the cause of
the fault, you have to acknowledge the fault message.
What is an Alarm?
An alarm is the response to a fault condition identified by the drive. It does not
result in the drive being switched off and does not have to be acknowledged.
Alarms are "self acknowledging", that is, they are reset automatically when the
cause of the alarm has been eliminated.
