12.3 Faults and alarms
12.3.1 Over
view of faults and alarms
Description
De󹪝nitions
A message includes a letter and a relevant number.
The letters have the following meaning:
• A means "Alarm"
• F means "Fault"
• N means "No message" or "Internal message"
• C means "Safety message"
In the delivery state (p3117 = 0), safety messages correspond to message type "C" and the
safety message bu󹪜er is active. With p3117 = 1, safety messages correspond to the message
types "A" or "F" and are stored in the fault bu󹪜er or the alarm bu󹪜er.
Di󹪜erences between faults and alarms
An alarm reports an operating state which is non-critical at present. A fault means that it is
normally no longer possible to run the motor. The converter therefore responds to alarms
and faults di󹪜erently.
