Overview Of Warnings And Faults - Siemens SINAMICS G150 Operating Instructions Manual

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 induction motor. The faults are
displayed and can be reported to a higher-level control system via PROFIdrive. In the
delivery condition, the message "Drive 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.
