4 Alarm and fault messages

4.1.1 Fault types

There are two different types of fault, i.e. plant faults and operational faults. Plant faults are caused by

malfunctioning of an inverter component, while operational faults occur as a result of unexpected external

influences or logical conditions of the control software.

Examples of plant faults:

• F48

• F65

• F97

Examples of operational faults:

• F94

• F96

It is however possible for an operational fault to be caused by a defective component.

Example: Fault 96 can be caused by a defective capacitor or transformer at the AC output.
