5.8 Faults and alarms
Indicating faults and alarms
If a fault occurs, the drive displays the fault and/or alarm on the 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.
Alarms are indicated by means of the yellow "ALARM" LED. The system also displays a note
in the status bar providing information on the cause.
What is a fault?
A fault is a message from the drive indicating an error or other exceptional (unwanted) status
that causes the drive to shutdown. This could be caused by a fault within the converter or an
external fault triggered, for example, by the winding temperature monitor for the 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.
Fault and alarm displays
Every fault and alarm is entered in the fault/alarm buffer along with time the error occurred.
The time stamp refers to the system time (r2114).
You can call up an overview screen that displays the current status of faults and/or alarms
for every drive object in the system by choosing MENU – Fault memory / alarm memory.
A context menu featuring the "Back" and "Quit" options appears when you press F4 "Next".
The function required can be selected using F2 and F3 and executed by pressing F5 "OK".
The "Acknowledge" function sends an acknowledgement signal to each drive object.
The red FAULT LED extinguishes once all the faults have been acknowledged.
