What is a fault?
A fault is a message from the drive indicating an error or an other exceptional (unwanted)
status. The cause can be a drive-internal fault or an external fault. The fault, for example, could
have been issued by the winding temperature monitoring of 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 "drive fault" is also sent to a relay output. Once you
have eliminated the cause of the fault, acknowledge the fault message.
The list of faults and alarms indicates the type of response (e.g. OFF1, OFF2) for each fault
message.
Displaying faults
Faults are displayed by the red "FAULT" LED. Any faults that have occurred are automatically
displayed. Up to eight faults occurring at the same time are displayed.
1. Use the <▲> or <▼> function key to select the fault.
2. Press the <Ack.> function key to acknowledge the fault. The operation screen is displayed.
3. Press the <Help> function key to fetch the information for clearing the fault.

What is an alarm?
An alarm is the response to a fault condition identified by the drive that does not result in the
drive being shutdown. Alarms do not need to be acknowledged. Alarms are "self
acknowledging", that is, they are reset automatically when the cause of the alarm has been
eliminated.
